Pinnacle Radiation Therapy Planning Software is a computer software package intended to provide support for radiation therapy treatment planning for the treatment of benign or malignant disease processes. Pinnacle Radiation Therapy Planning Software assists the clinician in formulating a treatment plan that maximizes the dose to the treatment volume while minimizing the dose to the surrounding normal tissues. The system is capable of operating in both the forward planning and inverse planning modes. The device is indicated for use in patients deemed to be acceptable candidates for radiation treatment in the judgment of the clinician responsible for patient care. Plans generated using this software are used in the determination of the course of a patient's radiation treatment. They are to be evaluated, modified and implemented by qualified medical personnel.
Device Story
Pinnacle3 RTP is a software-based radiation therapy planning system running on Sun UNIX workstations. It imports patient image data (CT, MR, PET, PET-CT, SPECT) via DICOM. Clinicians use the system to visualize anatomy, perform multi-modality image registration/fusion (Syntegra), and generate radiation treatment plans. The system supports forward and inverse planning modes, including conformal arc, stereotactic radiosurgery, and brachytherapy. It allows configuration of beam variables (energy, geometry, modifiers like MLCs, wedges, bolus). The system computes dose distributions, allowing clinicians to evaluate plans against radiation-sensitive structures. Output includes treatment plans transferred to record-and-verify systems, linear accelerators, or QA systems. Remote review is supported via P3MD. The device assists clinicians in maximizing dose to tumors while sparing normal tissue; final plans are evaluated and implemented by qualified medical personnel.

Device Description: Pinnacle Radiation Therapy Planning Software version 6.6 (hereafter Pinnacle RTP) provides radiation therapy planning for the treatment of benign or malignant diseases. When using Pinnacle3 RTP, qualified medical personnel may generate, review, verify, approve, print and export the radiation therapy plan prior to patient treatment. Pinnacle RTP can provide plans for various radiation therapy modalities including External Beam Treatment, Stereotactic Radiosurgery, and Brachytherapy.
Pinnacle RTP is a software package that runs on a Sun UNIX workstation and consists of a core software module (Pinnacle') and optional software features. These optional software features, commonly referred to as "plug-ins", are typically distributed separate from the core software product (separate CD-ROM). The device has network capability to other Pinnacle' workstations and to both input and output devices via local area network (LAN) or wide area network (WAN).
Image data is imported from CT, MR, PET, PET-CT and SPECT devices using a DICOMcompliant interface. A qualified medical professional uses the Pinnacle RTP for functions such as viewing and analyzing the patient's anatomy, and generating a radiation therapy plan. The following are examples of tasks that may be performed by clinicians when using the Pinnacles RTP system:
- Evaluate the treatment plan based on radiation-sensitive structures and the tumor.
- Combine both geometric and dosimetric planning on the same platform, including CT ● simulation data and plans. The CT simulation part of the system is called SmartSim.
- . Configure beam variables such as energy, geometry, and beam modifiers such as blocks, wedges, multi-leaf collimators, bolus and compensators.
- Visualize the beam on a display, initiate the dose computation, and set the weight of each beam.
{1}------------------------------------------------
- Obtain dose measurements from any Points of Interest (POI). ●
- Perform photon and electron physics modeling, dose algorithm and machine . commissioning. This functionality is supported by the Physics Utility Module.
- Evaluate images away from the workstation via a laptop or physician group workstation. . The feature that provides remote review is referred to as P'MD.
- Create data for use in conjunction with treatment QA systems. .
- Configure, backup, archive, restore, and scripting. .
- Evaluate Digitally Reconstructed Radiographs (DRRs) on Pinnacle RTP or remote system ● using DICOM Secondary Capture (SC) Export.
Once complete. Pinnacle has the ability to transfer the finished plan to other devices used in the therapy process such as Record and Verify, Linear Accelerator (Linac) Workstations and/or 3rd Party QA systems.
The following Pinnacle software features are also available to assist the clinician with the radiation therapy planning process. These features are distributed on standalone CD-ROM media, and installed onto the Pinnacle3 RTP workstation. Corresponding instructions for use such as User Guides or Release Notes are also provided to the clinician for each optional feature.
#### PIMRT (Intensity Modulated Radiation Therapy):
P IMRT combines both forward and inverse planning functionality. The system determines a plan that satisfies the user's treatment goals through an optimization process. The user's treatment goals are specified as objectives and constraints based on dose distribution characteristics.
#### Syntegra (also referred to as AutoFusion):
Syntegra automates multi-modality image registration and fusion by overlaying images from CT, MR, PET, PET-CT and SPECT devices using a DICOM-compliant interface. This feature provides clinicians with the ability to relate, interpret and contour an image's anatomic and functional information.
In addition to the above, the following software options are available to facilitate image and/or data import and export between radiation therapy devices such as the imaging camera, Pinnacle RTP, and Record & Verify system. DICOM is the acronym for Digital Imaging and Communications in Medicine and is an internationally recognized standard for transferring biomedical information such as images and data between devices or over a network.
{2}------------------------------------------------
## DICOM RT:
DICOM RT software is used to support both Structure Set and Radiation Therapy Plan import and export functions. Structure Sets describe regions and points of interest to other systems. Plan information includes beam geometry and delivery information.
#### DICOM Image:
DICOM Image software is used to support image import and export to and from the Pinnacle2 RTP workstation according to the NEMA DICOM standard, version 3.0. This functionality allows diagnostic imaging devices supporting the DICOM 3.0 standard to interface with the Pinnacle system.
### Mitsubishi DME:
A proprietary interface has been created within the Pinnacle3 Treatment Planning software to support plan export to Mitsubishi Record and Verify systems. This interface is called the "Mitsubishi DME" system. This is implemented as a simple file based interface according to a format specified by Mitsubishi.
# P MD:
P MD allows for treatment plan review and minor alternations by a physician from a PC-based workstation that is connected to the same network as the primary Pinnacle Treatment Planning workstation.
#### Indications for Use:
Pinnacle3 Radiation Therapy Planning Software is a computer software package intended to provide support for radiation therapy treatment planning for the treatment of benign or malignant disease processes.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
