Intended Use

AccuSoft is intended to be used for the computation, display, evaluation, and output documentation of radiation dose estimations including those for Intensity Modulated Radiation Treatment (IMRT), to be submitted for independent clinical review and judgment by a physicist or physician prior to use. The application provides output data in the form of displays or hardcopy printouts to guide a physician in selecting the optimum patient treatment plan. It is intended to provide a report to be used by a qualified professional such as a radiation oncologist, medical physicist, radiation therapist or dosimetrist.

Device Story

AccuSoft is a radiation treatment planning system (RTPS) software package; used by radiation oncologists, medical physicists, and dosimetrists in clinical settings. Input includes patient imaging data and delineation of anatomical structures/lesions. Device utilizes algorithmic approaches to calculate radiation dose distributions; enables beam planning techniques for irregularly shaped lesions. Output consists of displays and hardcopy printouts documenting dose estimations. Healthcare providers use these outputs to select optimal patient treatment plans, maximizing dose to lesions while minimizing dose to surrounding normal tissue and critical structures. System requires independent clinical review and verification by a physicist or physician prior to use.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on bench testing, software validation, and performance testing results.

Technological Characteristics

Radiation treatment planning software. Complies with IEC 60601-1-4 (Programmable electrical medical systems), IEEE 829 (Software Test Documentation), IEEE 830 (Software Requirements Specifications), and ISO 14971 (Risk Management). Features include image processing, anatomical delineation, and beam planning algorithms for dose calculation.

Indications for Use

Indicated for radiation dose computation, display, and evaluation for patients undergoing radiation therapy, including Intensity Modulated Radiation Treatment (IMRT). Intended for use by qualified professionals (radiation oncologists, medical physicists, radiation therapists, dosimetrists) to guide treatment planning.

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.
