No
The description focuses on precise electrical measurements and software control for quality assurance and dose measurement, with no mention of AI or ML techniques.
No
The device is used to perform quality assurance checks and measurements on therapeutic devices, and to measure radioactive sources for therapeutic or diagnostic treatment; it does not directly provide therapy.
No
The device is used to measure the output of therapeutic X-ray machines and radioactive sources, which are instruments used for treatment, not for diagnosing medical conditions in patients. It performs quality assurance checks on medical equipment.
No
The device description explicitly states it is a "low impedance electrometer" and mentions "adjustable + bias voltage," which are hardware components. While it is "software controlled," it is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is used to perform quality assurance checks and measurements on the output from therapeutic X-ray machines or teletherapy units, and to measure radioactive sources used for therapeutic or diagnostic treatment. These are measurements related to radiation therapy and nuclear medicine procedures, not tests performed in vitro on biological samples.
- Device Description: The description of the device as an electrometer used for dose or dose rate measurement further supports its use in radiation measurement, not in vitro diagnostics.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information based on the analysis of such samples.
Therefore, the device falls outside the scope of In Vitro Diagnostic devices.

Description of the test set, sample size, data source, and annotation protocol
The same NIST calibrated ionization chamber was used with both the 192 and 292 electrometers, and measurements were made under a variety of accelerator and orthovoltage machine settings.
After the addition of a CRC dose calibrator chamber to the 292, the same NIST radioactive sources were measured on the 292 and a CRC 15R dose calibrator.
Capintec has released several 292 units to selected radiation oncology facilitates for clinical testing and evaluation and provided testing procedures to each site.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Test results from both electrometers show excellent agreement to the limits of the reproducibility of the individual x-ray machines. In addition, the software algorithms were verified against manual calculations and agreement was 100%.
Results agreed to within 1%.
Acceptance criteria is 100% success in function and intended use.

§ 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.

510(k) SUMMARY
Submission Date: January 30, 1998
Pursuant to the requirements of Section 510(k) of the Food, Drug, and Cosmetic Act, notification is made of the intention of Capintec, Inc. to manufacture and market an electrometer used for output measurements of therapeutic x-ray machines, teletherapy units, or radioactive sources.
Capintec is divided into two physical locations as follows:

Classification Name: Electrometer IYE (892.5050) (accessory item to linear accelerator) Classification Number: Common or Usual Name: Electrometer Capintec Model 292 Electrometer Proprietary Name: Establishment Registration Number: 2518843 Regulatory Class: II
Description: The 292 is a precise and accurate software controlled low impedance electrometer with four measurement ranges, adjustable + bias voltage which can act as a dose or dose rate meter.

Substantial equivalence: The model 292 is a microprocessor based upgrade of the model 192 electrometer. Both units perform exactly the same function, measure current with high precision over a select range of interest, and convert the measured current to radiological units with appropriate conversion factors. Both units were developed for use with the same ionization chambers, and same application. The model 192 uses analog circuitry for measurement and calibration, while the 292 has replaced the analog circuitry with microprocessor based technology to provide enhanced performance specifications and better data manipulation. The 192 is a preamendment device which was first manufactured and distributed in 1973, and is still sold today.
Intended Use: The Capintec 292 electrometer is intended to be used by trained medical physicists or qualified radiation therapy technologists to perform quality assurance checks and measurements on the output from therapeutic linear accelerators or teletherapy units. With the addition of a Capintec CRC dose calibrator chamber, the 292 may also be used by trained medical physicists or qualified technologists to measure radioactive sources used for therapeutic or diagnostic treatment.
Test Results: The same NIST calibrated ionization chamber was used with both the 192 and 292 electrometers, and measurements were made under a variety of accelerator and orthovoltage machine settings. Test results from both electrometers show excellent agreement to the limits of the reproducibility of the individual x-ray machines. In addition, the software algorithms were verified against manual calculations and agreement was 100%.
After the addition of a CRC dose calibrator chamber to the 292, the same NIST radioactive sources were measured on the 292 and a CRC 15R dose calibrator. Results agreed to within 1%.
Capintec has released several 292 units to selected radiation oncology facilitates for clinical testing and evaluation and provided testing procedures to each site. Acceptance criteria is 100% success in function and intended use. Suggestions received for improvement in the software or hardware from these "beta test sites" will be evaluated, tested, and incorporated when appropriate. Any problems discovered during this process will be corrected prior to release to production for commercial shipment.
Conclusion: The 292 functions as intended and is substantially equivalent in performance and intended use to the 192 electrometer for measurement of output from therapy x-ray machines and equivalent to the CRC15R dose calibrator in performance and intended use for the measurement of radioactive sources used in therapy or diagnostic applications. The 292 provides significantly improved performance specifications and better data manipulation compared to its predicate devices.
