The CNMC Model 206 is a medical dosimeter, or medical electrometer that is capable of performing measurements of diagnostic and therapeutic amounts of ionizing radiation when an appropriate ionization chamber or diode dosimeter is connected. These instruments are used exclusively by qualified personnel, typically medical physicists, for the calibration and quality control of medical equipment that produces ionizing radiation.

The CNMC Model 206 is a dosimetry electrometer intended for measuring the output charge of an Ionization chamber or dosimetry diode that is used in a radiotherapy beam.

Here's an analysis of the provided text regarding the acceptance criteria and study for the CNMC Model 206 Electrometer/Dosimeter:

General Note: The provided document is a 510(k) Premarket Notification Summary from the FDA. This document primarily focuses on establishing "substantial equivalence" to a predicate device, rather than providing a detailed report of a new clinical study with specific acceptance criteria and performance data for a novel device. Therefore, many of the requested items (e.g., sample sizes, ground truth establishment, expert qualifications, MRMC studies) are not typically found in this type of regulatory submission because the device is not a complex AI/ML system requiring extensive clinical validation. Instead, the focus is on demonstrating that the new device performs comparably to an already approved device.

Description of Acceptance Criteria and Study to Prove Device Meets Acceptance Criteria

Summary: The CNMC Model 206 Electrometer/Dosimeter is primarily evaluated for "substantial equivalence" to a predicate device (Sun Nuclear Model 1010/206 – K002444). The acceptance criteria are implicitly defined by the specifications of the predicate device and the new device's ability to meet those specifications. The "study" demonstrating this involves comparing the technical specifications and intended use of the CNMC Model 206 to the predicate device.

1. A table of acceptance criteria and the reported device performance

Since this is a substantial equivalence submission, the "acceptance criteria" are the performance specifications of the predicate device, and the "reported device performance" is how the CNMC Model 206 matches or is equivalent to those specifications.
