The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the description of the device and its function does not suggest the use of AI/ML for dose calculation or analysis. The software is described as a "simple software tool" for calculation, reporting, and data management.
No
The device is used for measuring radiation dose for quality control and secondary verification in medical dosimetry, not for directly treating a condition or disease.
No
The device is described as a medical dosimetry system for measuring radiation dose, providing secondary verification of radiation dose (for quality control), and not for adjusting patient dose. This falls under measurement and verification, not diagnosis.
No
The device description explicitly lists hardware components like a "Dosimeter (nanoDot)", a "Reading device (microSTARii Reader)", and a "2D barcode scanner" in addition to the software application.
Based on the provided information, the LANDAUER® microSTAR®ii Medical Dosimetry System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- microSTAR®ii Function: The microSTAR®ii system measures radiation dose on-phantom or on-patient. It does not analyze biological specimens from the body. Its purpose is to verify radiation dose delivered during medical procedures, not to diagnose or monitor a patient's health status through analysis of bodily fluids or tissues.
- Intended Use: The intended use explicitly states it's for "measuring dose on-phantom or on-patient in medical dosimetry applications" and provides "secondary verification of radiation dose as a means of Quality Control." This aligns with a device used in radiation therapy or diagnostic imaging procedures, not for analyzing biological samples.
Therefore, the microSTAR®ii system falls under the category of a medical device used in the delivery and verification of radiation, not an IVD.
N/A
Intended Use / Indications for Use
The LANDAUER® microSTAR®ii Medical Dosimetry System provides an accurate, reliable and easy-to-use dosimeter and reader intended for use in measuring dose on-phantom or on-patient in medical dosimetry applications, such as radiotherapy and diagnostic radiology. When used to measure patient dose, the system is used to provide a secondary verification of radiation dose as a means of Quality Control for the primary dose calculation method. The output of the microSTAR®ii system is not used to adjust the dose to the patient.

Dear Mr. Ennis:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

| Comparison to Predicate: | Though the indications for use are slightly different from the predicate, the intended use remains the same between the proposed device and predicate device (capturing and displaying radiation dose) and the proposed differences in indications are for clarity and do not have impact on safety or effectiveness. The microSTARii system utilizes OSL (optically-stimulated luminescence) dosimeters whereas the predicate utilizes MOSFET (Si-based metal-oxide-semiconductor field-effect transistor) dosimeters.
The proposed device employs the same fundamental scientific technology and these technological differences do not raise different questions of safety or effectiveness. |
