Device Story

3Dicom MD is a software application for 2D/3D visualization and analysis of medical images (CT, MRI, PET). It ingests DICOM data from onsite PACS, local storage, or external media (USB/CD/DVD). The software provides tools for multi-planar reconstruction (MPR), 3D volumetric rendering, measurements (length, angle, area), and annotations. It supports real-time remote collaboration, including screen-sharing, voice, and text chat. Used by radiologists and clinicians on Windows or Mac workstations, the device enables interactive review of patient scans. Healthcare providers use the visual output to assist in clinical decision-making and diagnostic assessment. The software facilitates secure, collaborative review of diagnostic-quality images, potentially improving clinical workflow and communication between medical professionals.

Clinical Evidence

No clinical testing was performed. Safety and effectiveness were demonstrated through non-clinical bench testing, including software verification and validation. Measurement accuracy for length, area, and angle was validated using 81 Digital Reference Objects, achieving 98.8% to 99.52% accuracy. Usability testing was conducted with trained healthcare professionals.

Technological Characteristics

Software-based medical image management and processing system. Supports DICOM standard. Features include 2D multi-planar reconstruction (MPR), 3D volumetric rendering, and measurement tools. Operates on local Windows or Mac computers. Implements cybersecurity controls per FDA guidance. Classified as moderate level of concern software.

Indications for Use

Indicated for use by qualified medical personnel in hospitals, imaging centers, and reading practices as a diagnostic and analysis tool for CT, MRI, and PET diagnostic images. Not for diagnostic use with mammography images or on mobile devices.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

#### Performance data

Software verification and validation activities for 3Dicom MD were performed in accordance with FDA quidance Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices (May 2005), including measurement accuracy and usability tests.

3Dicom MD is considered a "moderate" level of concern.

Singular Health has implemented security features for the device and data protection. Cybersecurity requirements, risk analysis, and mitigation was addressed in accordance with FDA guidance Content of Premarket Submission for Management of Cybersecurity in Medical Devices (Oct 2014).

No clinical testing was required to demonstrate safety or effectiveness for the subject device as the device's non-clinical (bench) testing was sufficient to support the intended use of the device.

The measurement accuracy for the length, angle, and area features was validated using Digital Reference Objects compared against the known values or the reference device. The Digital Reference Objects (n=81 test cases) created were representative of the clinical range typically encountered in radiology practice (1-180 mm). Inter-operator error (reproducibility), and intra-operator error (repeatability) were assessed.

| Measurement accuracy | |
|----------------------|--------|
| Length (>10 mm) | 99.3% |
| Length (1-10 mm)^ | 98.8% |
| Area | 99.52% |
| Angle | 99.46 |

^The tested accuracy for the lowest clinical range (1-10mm) was found to be slightly inferior (98.8%), due to the resolution of the input scan (Row Count and Column Count) and resolution of the screen.

## Evaluation of similarities and differences

3Dicom MD and the predicate have the same intended use, main images functionalities, and collaborative/sharing functions. In term of use and functions, both systems access, upload, and display DICOM images and metadata, and provide tools and resources to trained healthcare professionals for study review and analysis.

{7}------------------------------------------------

The main differences between both systems consist of the system access (local installation for 3Dicom MD versus web-based for the predicate). There are also minor differences in layout and some image functionalities. These differences do not present different questions of safety or effectiveness than the predicate device because safety and cybersecurity requirements have been defined and implemented, then tested and verified by a cybersecurity assessment, and the clinical functionalities have been tested by usability testing involving trained healthcare professionals.

## Conclusions

3Dicom MD and the predicate have the same intended use and indications, technological characteristics, and principles of operation. There are no differences between the devices that affect the usage, safety and effectiveness. The non-clinical performance data and software verification and validation demonstrate that 3Dicom MD performs comparably to and is as safe and effective as, the predicate device. In accordance with the 21 CFR Part 807 and based on the information provided in this premarket notification, 3Dicom MD is substantially equivalent to the predicate.
