MODEL 580-006 RADIATION THERAPY IONIZATION CHAMBER
This instrument is intended for the purpose of calibrating and measuring the ionizing radiation outputs from medical therapy machines.
The Model 580-006 Radiation Therapy Ionization Chamber is modeled after the traditional 0.6cm Farmer-type chamber used for absolute dosimetry measurements of medical linear accelerators and 900 machines. Each chamber includes an energy response chart, a PMMA 600 buildup cap, a convenient low noise one meter cable with triaxial BNC connector and a custom carrying case.
The provided document is a 510(k) Premarket Notification Summary for a medical device, the Model 580-006 Radiation Therapy Ionization Chamber. This type of document is for demonstrating substantial equivalence to a predicate device, not for a study proving device performance against acceptance criteria in the way a clinical trial or AI algorithm validation would.
Therefore, many of the requested categories (such as sample size for test/training sets, data provenance, expert ground truth, adjudication methods, multi-reader multi-case studies, standalone performance for AI, and ground truth establishment for training) are not applicable to this type of regulatory submission for a physical medical device like an ionization chamber. The "study" here is essentially the comparison of specifications and characteristics to a predicate device.
Here's an attempt to answer the questions based only on the provided text, indicating where information is not present or not applicable to this type of device submission:
Acceptance Criteria and Device Performance Study Summary
1. A table of acceptance criteria and the reported device performance
The document provides a "Specification Comparison Table" where the new device (Model 580-006) specifications are presented alongside the predicate device (Model 500-6) specifications. In the context of a 510(k) submission, the "acceptance criteria" are generally that the new device's specifications and performance fall within an acceptable range, demonstrating substantial equivalence to the predicate device, or that any differences do not raise new questions of safety or effectiveness. The table below presents the new device's specifications as its "reported performance" and the predicate device's specifications as the "benchmark" for substantial equivalence.
Feature | Predicate Device (Model 500-6) (Acceptance/Benchmark) | New Device (Model 580-006) (Reported Performance) |
---|---|---|
Volume | 0.6 cm³ | 0.61 cm³ |
Sensitivity | 2 x 10⁻¹⁰ A/R/s | 2.0 x 10⁻⁸ cGy⁻¹ |
