Indications for Use

CDMS is a Microsoft Windows based software application designed to record and manage physics data acquired during acceptance testing, commissioning and calibration of radiation therapy treatment devices. In addition, CDMS uses the same physics data to allow users to perform MU calculations based on treatment field parameters that are either imported from the treatment planning system or entered manually. CDMS is also used to manage linac calibration using standard protocols.

Device Story

CDMS is a Windows-based software for radiation therapy quality assurance; manages physics data from commissioning, acceptance testing, and calibration of linear accelerators. Inputs include technical specifications, measured physics data from water phantoms, and treatment field parameters imported via DICOM RT or manual entry. Operates by comparing measured data against peer-reviewed/manufacturer values; performs MU calculations using Khan (classical) algorithm. Used by medical physicists in clinical settings to verify treatment plan quality and manage linac calibration per AAPM TG-51/TG-40 protocols. Outputs include calculated dose/MU values and calibration reports in Word, Excel, or PDF formats. Facilitates regulatory compliance and audit readiness through structured data storage.

Clinical Evidence

No clinical data; bench testing only. Validation included importing measured physics data, performing monitor unit/dose calculations, and executing linear accelerator calibration per TG-51, with side-by-side comparisons to predicate performance.

Technological Characteristics

Windows-based software; minimum Pentium II processor. Uses Khan (classical) dose calculation algorithm. Supports DICOM RT data import. Exports to Word, Excel, or PDF. Three-level password-protected user security. Manages data for linear accelerators with multi-modality energies, photon/electron particles, field blocking, linear wedges, and MLCs (52, 80, 120 leaf).

Indications for Use

Indicated for use by medical physicists to record/manage radiation therapy device physics data, perform monitor unit (MU) calculations for treatment plans, and manage linear accelerator (linac) calibration using standard protocols.

Regulatory Classification

#### (4) Device Description:

CDMS is a software program designed to record radiation beam data acquired during the commissioning, acceptance testing and calibration of a radiation therapy treatment device.

IMSure.

K031975

A CDMS session would look like this:

- 1. A new treatment machine is installed. The commissioning physicist enters its technical specification in CDMS.
- 2. A third party FDA approved water phantom is used to measure the physics characteristics of each beam generated by the machine.

{1}------------------------------------------------

- 3. Measured physics data is imported to CDMS.
- 4. Measured data in CDMS is compared to peer reviewed/published or manufacturer provided measured values.
- Treatment plans generated by a radiation therapy treatment 5. planning system imported to CDMS via DICOM RT.
- 6. Imported treatment fields parameters are used in conjunction with CDMS stored measured physics data to calculate dose and/or monitor units.
- 7. The difference between planned and CDMS calculations is used as a measure of the quality of the treatment plan (QA).

The above workflow is only given as an example to illustrate how the application is used. Other steps may be added to the workflow or may be left out, for example performing a query of the measured physics data based on beam type, energy and field geometry and saving calibration parameters for use on a monthly QA basis.

#### Intended Use: (5)

CDMS is a Microsoft Windows based software application designed to record and manage physics data acquired during acceptance testing, commissioning and calibration of radiation therapy treatment devices. In addition, CDMS uses the same physics data to allow users to perform MU calculations based on treatment field parameters that are either imported from the treatment planning system or entered manually. CDMS is also used to manage linac calibration using standard protocols.

#### (6) Technological Comparison:

The intended use of CDMS is the same as the predicate devices with a few additions that do not affect the safety and effectiveness of the device.

CDMS differs from the predicate devices by allowing for the management linear accelerators calibration according to American Association of Physicists in Medicine (AAPM) Task Group 51. This feature is equivalent to using an excel sheet to perform the required calibration and save the necessary parameters for future use on monthly basis following AAPM Task Group 40 recommendations. It is therefore not seen to be a threat to patient safety and effectiveness. In fact, it is seen as an enhancement because it will allow for proper storage of calibration parameters as well as better management of calibration reports in format that is easily accessible to external auditors, state and federal regulators.

### (7) Non-Clinical tests:

The non-clinical tests involved using CDMS to import measured physics data, to perform numerous monitor unit/dose calculations and to calibrate a linear accelerator according to TG-51. Side by side comparison tables are shown in the supporting Validation & Verification documentation

#### Clinical tests: (8)

Due to the fact that the system is a software application that is not directly involved with patient treatment delivery, no clinical tests were performed.

#### Conclusion: (9)

According to the intended use, technological characteristics and non-clinical testing, CDMS is substantially equivalent to IMSure and RadCalc, Model V4.0 (the predicate devices). The documentation presented in this submission supports the claim of substantial equivalence.

Dear Dr. Adnani:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). 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 II (Special Controls) or class III (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
