Intended Use

The ACQPLAN is an integrated 3-D RTP and simulation system embedded in a volumetric image processing computer environment. AcQPlan is intended to be used to plan radiation therapy treatments on linear accelerators and other similar teletherapy devices with x-ray beams of energies from 4 to 50 MV, cobalt-60, and electron beams with energies from 4 to 50 MeV of the entire human anatomy. It allows the treatment planner to employ such techniques as asymmetrically collimated fields, irregular fields, multi-leaf collimators, non-coplanar fields, bolus, fixed wedges, and Varian's enhanced dynamic wedges. It allows the treatment planner to take heterogeneities into account for photon beams using two versions of the Batho method or the Equivalent TAR (ETAR) method, and it uses a generalized Gaussian pencil beam model for electron beams. Using AcQPlan, the treatment planner can simultaneously visualize target and normal tissues and the computed 3-D dose distributions in great detail, on a real-time basis. The treatment planner develops treatment plans in a coordinate system accurately fixed to set-up marks on the patient, using CT and multi-modality information made possible by volumetric 3-D image processing. Tools for managing competing and complementary plans are provided. Tools, based on DVH plots, are provided for comparing competing plans. High quality DRRs and DCRs (digitally composited radiographs), with BEV and beam graphics superimposed, are generated to replace conventional simulator films. This device may include signal analysis and display equipment, patient and equipment supports, components and accessories. This device may include signal analysis and display equipment, patient and equipment supports, components and accessories.

Device Story

ACQPLAN is an integrated 3-D radiation therapy planning (RTP) and simulation system. It ingests CT and multi-modality volumetric image data to facilitate treatment planning. The system enables planners to define treatment fields—including asymmetric, irregular, multi-leaf collimator, and non-coplanar fields—and apply bolus or wedges. It calculates dose distributions using Batho or ETAR methods for photons and a generalized Gaussian pencil beam model for electrons. The system generates high-quality digitally reconstructed radiographs (DRRs) and digitally composited radiographs (DCRs) with beam's-eye-view (BEV) graphics, replacing conventional simulator films. Operated by trained healthcare professionals in a clinical environment, the system allows real-time visualization of targets, normal tissues, and 3-D dose distributions. Planners use dose-volume histogram (DVH) tools to compare competing plans. The device assists in precise treatment delivery by fixing plans to patient set-up marks, ultimately aiming to optimize radiation therapy accuracy and patient outcomes.

Clinical Evidence

Bench testing only. Effectiveness established through internal evaluation throughout development phases, confirming performance in accordance with specifications.

Technological Characteristics

Integrated 3-D RTP system; volumetric image processing computer environment. Supports photon (4-50 MV) and electron (4-50 MeV) beam modeling. Implements Batho/ETAR methods for photon heterogeneity and Gaussian pencil beam model for electrons. Conforms to IEC 601-1 and UL 187 safety standards. Includes signal analysis, display equipment, and patient support accessories.

Indications for Use

Indicated for radiation therapy treatment planning for patients requiring teletherapy (linear accelerators, cobalt-60) with photon (4-50 MV) or electron (4-50 MeV) beams across the entire human anatomy.

Regulatory Classification

Identification

A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.

### Picker 510(k) Notice

### ACQPLAN Summary of Safety and Effectiveness

This is a summary of the information submitted by Picker International, Inc. to the Office of Device Evaluation (ODE), specifically DRAERD of the FDA as required by the Federal Food, Drug, and Cosmetic Act as amended on November 18, 1990 in section 513(f)(3).

The ACQPLAN is an integrated 3-D RTP and simulation system embedded in a volumetric image processing computer environment. AcQPlan is intended to be used to plan radiation therapy treatments on linear accelerators and other similar teletherapy devices with x-ray beams of energies from 4 to 50 MV, cobalt-60, and electron beams with energies from 4 to 50 MeV of the entire human anatomy.

High quality DRRs and DCRs (digitally composited radiographs), with BEV and beam graphics superimposed, are generated to replace conventional simulator films. This device may include signal analysis and display equipment, patient and equipment supports, components and accessories.

Preliminary functional specifications and operator's instructions are included in the Attachments "B" and "C" respectively. Final documentation will be provided with production units.

The ACQPLAN is substantially equivalent to legally marketed devices and is under control of health care professionals who are trained and responsible for computed tomography examinations. Labeling (Product Specification and Operator's Manual) will be provided to the user of the equipment.

Picker adheres to FDA 21 CFR 820 and voluntary standards for safety and effectiveness (UL 187) all of which mandate that components are tested to minimize hazards (electrical, mechanical, and radiation). In addition, the system is designed to conform to IEC 601-1.

Effectiveness is established by Picker's evaluation throughout all phases of the ACQPLAN development. The product will perform in accordance with the development specifications. The ACQPLAN represents the current state-of- the-art technology, therefore, is equivalent to legally marketed devices.

Picker has reviewed all known information and performed an investigation as to the causes of safety and effectiveness concerning the ACQPLAN. In addition, all information contained in this 510(k) Notice is accurate and complete.

Dear Mr. Turocy:

SEP

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register.
