The device description focuses on the physical properties and manufacturing process of the compensator, with no mention of AI or ML. The performance studies describe physical measurements of radiation attenuation.
No.
The device is used to modulate the intensity of a radiation beam during therapy, not to directly treat a medical condition or disease.
No
The device is a compensator used to modulate beam intensity during radiation therapy, which is a treatment modality, not a diagnostic one.
No
The device description clearly states it is a physical compensator made of brass/aluminum with tungsten fillings, which is a hardware component used in radiation therapy.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "modulation of beam intensity during radiation therapy." This is a therapeutic application, not a diagnostic one.
- Device Description: The device is a physical object (compensator) used to shape the radiation beam. It does not interact with biological samples (blood, tissue, etc.) to provide diagnostic information.
- Performance Studies: The performance studies focus on measuring the attenuation of the radiation beam, which is relevant to the device's function in radiation therapy, not in vitro diagnostics.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Intended Use / Indications for Use
The Oncology Tech Mod1T Radiation Beam Therapy Compensator is designed specifically for application in external beam radiation therapy in cancer treatment. The device could be used in this application for all types of cancer treatable by external beam radiation therapy, with a universal application to this patient population.
The Oncology Tech precision milled brass/aluminum compensators with tungsten fillings in the compensator walls are used for modulation of beam intensity during radiation therapy.

Device Description
The Oncology Tech Mod1T Compensators for Radiation Beam Therapy are used for modulation of beam intensity during radiation therapy. Typically, a brass or aluminum round is used as a basis for the compensator. It is placed into the milling machine and worked into precise X, Y and Z dimensions. The new design of Oncology Tech Mod1T compensators mills out the compensator brass or aluminum walls and adds a high density material. The higher density of the fill material in the compensator walls provides for more attenuation and less radiation transmission at the field edges.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The attenuation was measured with a Sun Nuclear profiler in the transverse or cross table plane. Each compensator was locked in place in the tray holder accessory for the linear accelerator. The gantry of the linear accelerator was set at 0 degrees so that it was pointing directly towards the floor. A collimator rotation was also at 0 degrees. The test device was placed on the table used to treat patients and carefully aligned with the collimator crosshairs. The table was raised to the distance that was normally used for standard QA measurements according to the manufacturer instructions. Each compensator was irradiated with 100 monitor units of radiation. The transverse plane attenuation for each compensator was then recorded and compared to the brass compensator baseline: These test results are shown in Appendix A, located within the step 20 clinical testing section of this submission. The measurement results show an improvement of the attenuation under the compensator walls for both the 6X and 18X beams. The addition of the high density fill to the compensator walls at the field edge provides greater attenuation of the photon beam at the field edge and less dose outside the field.

Summary
Trade Name: Mod1T Compensators for Radiation Beam Therapy
Common Name: Compensator
Classification Name: block, beam shaping, radiation therapy
Predicate Device: The predicate device is "Mod1 Compensators for Radiation Beam Therapy", by Symtium Corporation, FDA number: K062781.

The device could be used in this application for all types of cancer treatable by external beam radiation therapy, with a universal application to this patient population.
Technological Characteristics of the Device:
The predicate device for comparison purposes is the "Mod1 Compensators for Radiation Beam Therapy", by Symtium Corporation, FDA number: K062781. The Oncology Tech Mod1T Radiation Beam Therapy Compensator has the same intended use and similar characteristics to the predicate device.

Determination of Substantial Equivalence:
The attenuation was measured with a Sun Nuclear profiler in the transverse or cross table plane. Each compensator was locked in place in the tray holder accessory for the linear accelerator. The gantry of the linear accelerator was set at 0° so that it was pointing directly towards the floor. A collimator rotation was also at 0°.
