No
The summary describes a software program for independent verification of IMRT plans and monitor unit calculations based on physics data. There is no mention of AI, ML, or related concepts, and the description of its function aligns with deterministic calculation methods rather than learning algorithms.
No.
This device is a quality assurance tool used to verify IMRT treatment plans and calculate monitor units; it does not directly treat or diagnose patients.
No
The device is described as a "quality assurance tool" and a "second, independent verification of IMRT plans," which explicitly states its function as a QA tool, not for directly diagnosing a medical condition in a patient.
Yes
The device description explicitly states "IMSure is a software program" and describes its function as a calculation and comparison tool for radiation therapy plans, without mentioning any associated hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- IMSure's Function: IMSure is described as a software program used for quality assurance of radiation therapy treatment plans. It verifies calculations and compares results from existing treatment plans.
- No Specimen Analysis: There is no mention of IMSure analyzing any biological specimens from a patient. Its input is radiation therapy plan data, not patient samples.
Therefore, IMSure falls under the category of a medical device used in the planning and quality control of medical treatments, but it does not meet the definition of an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
IMSure is intended for use as a quality assurance tool to verify IMRT treatment plans developed on any radiation therapy treatment planning system with the appropriate transfer format. IMSure will also perform primary monitor unit calculations from measured physics for plans of known geometry.

Device Description
IMSure is a software program designed to provide a second, independent verification of IMRT plans created on primary radiation therapy treatment planning systems. After independently calculating the imported plan and fluence maps, IMSure compares results with the imported plan and maps, and calculates the differences. This second check provides an effective QA tool for verification of the original IMRT treatment plan.
IMSure also may be used to compute primary monitor unit calculations for single and multiple beams with open, blocked, and wedged fields.

§ 892.5050 Medical charged-particle radiation therapy system.
(a)
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.(b)
Classification. Class II. When intended for use as a quality control system, the film dosimetry system (film scanning system) included as an accessory to the device described in paragraph (a) of this section, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Dear Mr. Welte:
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 enactnient 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 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at one of the following numbers, based on the regulation number at the top of the letter:
| 8xx.1xxx | (301) 594-4591 |
