The description details a physical ionization chamber for collecting radiation beam data. There is no mention of software, algorithms, or data processing that would suggest the use of AI or ML.
No
The device is described as an ionization chamber used for collecting beam data from radiation therapy treatment machines, indicating it is a measurement and quality assurance tool, not a device directly used for therapy.
No
The device collects beam data from radiation therapy treatment machines to document beam characteristics and for quality assurance, not to diagnose a patient's medical condition.
No
The device description clearly describes physical ionization chambers with specific dimensions, materials, and cable connections, indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for collecting beam data from radiation therapy treatment machines in phantoms (water, air, solid state material). This data is used for documenting beam characteristics and quality assurance of the treatment machine itself.
- Device Description: The device is an ionization chamber, which measures radiation dose.
- Lack of Biological Sample Analysis: IVD devices are designed to perform tests on biological samples (blood, urine, tissue, etc.) to diagnose, monitor, or screen for diseases or conditions. This device does not interact with or analyze any biological samples.
The device is used in the context of medical treatment (radiation therapy), but its function is to measure the physical properties of the radiation beam, not to diagnose or analyze a patient's biological state.

Device Description
The PTW T31006 and T31007 are classical waterproof ionization chambers that differ only in the lengths of their respective active volumes. The T31006 is a 0.015 cc ionization chamber with a 5 mm active length and the T31007 is a 0.005 cc ionization chamber with a 2 mm active length. Both chamber volumes are open to the atmosphere, they are waterproof, and they are vented via their connectors. These chambers are constructed of precisely the same materials, are available with a 1 m or 10 m cable for connection to an electrometer, and may be terminated in a variety of standard electrometer connectors (BNT, TNC, PTW M, or BNC banana.
The Pinpoint type ionization chamber, when connected to an appropriate electrometer like the PTW-UNIDOS, K951764, are used to collect beam data from radiation therapy treatment machines.

Dear Mr. Szeglin:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). You may, therefore, 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 misbranion.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under Radiation Control provisions, or other Federal laws or regulations.

Premarket Notification Indication For Use Statement
510(k) Number (if known): Not assigned as of June 9, 1997
0.015 cc Pinpoint type ionization chamber, Device Name: 0.005 cc Pinpoint type ionization chamber.
Indications For Use:
High quality ionization chambers, like the PTW T31006 and T31007 Pinpoint type ionization chambers make it possible to routinely measure, record, and document therapeutic amounts of ionizing radiation with an exceptionally high degree of accuracy and precision.
This type of lonization chamber is intended to be used for the collection of radiation beam data from radiation therapy treatment machines in water, air, or other suitable solid state phantoms. Since the T31006 and T31007 Pinpoint chambers are waterproof, they are ideally suited for measurements of high energy photons and electrons in a water phantom.
The data acquired with this type of chamber can be used to completely document the beam characteristics of treatment machines, compile radiation beam data over time as part of a quality assurance program, and to establish an initial baseline for the radiation therapy beams generated by the treatment unit.
High quality ionization chambers, like the PTW Pinpoint type chambers, are essential if accurate data from treatment machines that produce therapeutic amounts of ionizing radiation are to be properly monitored.
