Indications for Use

The intended purpose of the Diamond Edition of Setup 2000 Version 3.0 software is to provide an accurate and convenient method of independently checking, on a point dose basis, the treatment planning calculations of the primary radiation treatment-planning (RTP) computer. The primary RTP computer is capable of importing CT images of the patient, identifying target volumes, superimposing the treatment beams and optimizing the weighting and modulation of the beam to produce an acceptable radiation distribution within the patient. The Diamond Edition of Setup 2000 Version 3.0 calculates point doses under specified conditions communicated to the software through operator interaction (keyboard and mouse) or through file import.

Device Story

Diamond Edition of Setup 2000 Version 3.0 is a software tool for medical physicists to perform independent verification of radiation therapy treatment plans. Input data includes treatment parameters entered via keyboard/mouse or imported via standardized files (e.g., RTP Connectivity Protocol) from primary treatment planning (RTP) computers or record-and-verify systems. The software uses published literature models and a user-validated database of machine physical parameters to calculate monitor units (MU) or point doses. It features an Error Avoidance System (EAS) and collimator scatter modeling (points-eye-view of flattening filter, jaws, and MLC). Output consists of documented reports for patient charts. Used in clinical environments on PCs or networked workstations; does not control radiation delivery. Benefits include reduced operator error, standardized calculation methods, and improved quality assurance for complex treatments like IMRT. It supports management of active/inactive patient data and provides security features for machine file integrity.

Clinical Evidence

No clinical trials were performed. Evidence consists of bench testing, system validation, and alpha testing in complex clinical environments (e.g., MD Anderson Cancer Center). The software has a history of use since 1984 (DOS version) and 2001 (Windows version) with no reported calculation errors. Risk and hazard analysis demonstrate mitigation of potential data integrity and calculation hazards through internal validation checks and pre-calculation validation.

K032881 P1A3

#### Introduction

This software is designed specifically for the purpose of providing the medical physicist and other qualified health professionals a powerful and effective quality assurance tool for the analysis and verification of radiation therapy treatment plans generate by modern treatment planning computer systems. While this document describes the efforts to make this software safe and effective for it's intended use, it should be understood that the proper use of this device promotes better patient care by bridging the ever increasing gap between the sophisticated calculation capability of the modern treatment planning computers and the otherwise limited calculational resources normally available to the individuals responsible for independent verification. The use of this software also reduces operator errors through the use of active internal validation of user inputs and other machine limitations prior to performing a calculation.

#### Description

The Diamond Edition of Setup 2000 Version 3.0 software program is designed to operate in a Microsoft Windows environment either on a sinqle PC or on a workstation with the treatment machine and patient data shared on a server. This software does not control any device that delivers radiation to the patient. This software does not communicate directly with the treatment machine, the primary treatment planning (RTP) computer or the record and verify system. This software does have the ability to transfer treatment data files in a standardized format (e.g. RTP Connectivity Protocol by IMPAC) from the primary treatment planning computer or R&V system to facilitate the entry of the data to the software and the transfer of data to the R&V system for electronic charting. The software calculates the treatment machine monitor units (MU or time as appropriate) or dose to validate the values calculated by the RTP computer or to provide the settings for simple treatments not requiring the RTP plan prescribed by the physician. The software provides these calculations using methods and models published in the professional literature, the specific treatment information provided by the user and the values in a treatment machine database of measured physical parameters entered and validated by the medical physicist. The results of calculations are documented in printed or electronic reports to be placed in the patient's chart.

Intended use and Substantial Equivalence

The intended use of Diamond Edition of Setup 2000 Version 3.0 is the same as the named predicated devices. The Diamond Edition of Setup 2000 Version 3.0 and the predicated devices are equivalent in the following ways:

- 1. Allow the calculation of MU or dose under user specified parameters.
- 2. Use similar calculation methods based in the literature.
- 3. Use a treatment machine database for look up, interpolation and calculation of results.

### Summary of Safety and Effectiveness

K& S has a long history with dose calculation software beginning in 1978 with a first release to the public in 1984. This history is based on fulfilling the needs of a medical physics consulting organization by designing software to not only perform the required task but also to assist in the ongoing need to reduce errors in calculations and to help standardize the calculation methods of all members of the radiation oncology team including the medical physicist, the dosimetrist, the therapist and the radiation oncology physician. Quality patient care is achieve only when all members of the medical team participate in and are part of a coordinated quality system. The Diamond Edition of Setup 2000 Version 3.0 helps achieve this goal through a simple, reliable design that is easy to understand and easy for the operator to use. Significant effort has been expended to design, specify, code, test and produce a software product that is as safe and effective as reasonably possible under the usual conditions of cost versus benefit. This document describes this effort. After the software version has been alpha tested (System Tests and Validation Tests) at the K&S facility, a network of selected knowledgeable and qualified users. others under the supervision of K&S and QED consultants and institutions such as the MD Anderson Cancer Center test the software in a complex clinical environment to identify any needed changes. A confidential copy of their report on an earlier version of Setup 2000 is included. It is important to understand that K&S is both the customer and the developer and our professional medical physics practice depends on a reliable software product. K&S has a software quality program that includes audits of tests and records and a staff accustomed to satisfying quality issues as evidenced by three accreditations for the calibration services provided for nearly 20 years. We require this software to be accurate, reliable, dependable and efficient to serve our consulting needs and these requirements ensure that the software is thoroughly tested before release. The DOS Setup program has been in use by hundreds of highly qualified professionals across the US since 1984 without a single reported incidence of calculation error. The Windows software has been in clinical use since 2001 and has been in continuous refinement and development. It has been a slow process because we have required each incremental change to be thoroughly mastered before the next change.

In summary, we consider the Diamond Edition of Setup 2000 Version 3.0 Dose Calculation Management software to be safe and effective for its intended use.

# Indications for Use

K 032886 510(k) Number (if known):_____________________________________________________________________________________________________________________________________________________

Device Name: Diamond Edition of Setup 2000 Version 3.0

Indications For Use:

The current standard of care (AAPM, ACMP, ACR, etc.) in radiation oncology requires that the calculation results of each computer generated treatment plan be checked by some independent method. In the case of IMRT there is an additional requirement to perform measurements with ion chambers, TLD, film or other appropriate devices to ensure the accurate setup and delivery of the prescribed dose to the target organ and the limitation of dose to nearby sensitive organs. The medical physicist has the primary responsibility for these quality assurance checks and independent calculations. The intended purpose of the Diamond Edition of Setup 2000 Version 3.0 software is to provide an accurate and convenient method of independently checking, on a point dose basis, the treatment planning calculations of the primary radiation treatment-planning (RTP) computer. The primary RTP computer is capable of importing CT images of the patient, identifying target volumes, superimposing the treatment beams and optimizing the weighting and modulation of the beam to produce an acceptable radiation distribution within the patient. The Diamond Edition of Setup 2000 Version 3.0 calculates point doses under specified conditions communicated to the software through operator interaction (keyboard and mouse) or through file import.
