FDA PRODUCT CODE · CLASS II
QKB — Radiological Image Processing Software For Radiation Therapy
To provide semi-automatic or fully-automated radiological image processing and analysis tools for radiation therapy. Software implementing artificial intelligence (AI) including nonadaptive machine learning algorithms trained with clinical and/or artificial radiological images. In these devices, the algorithm training images typically impact device performance. AI based radiological image processing software is intended to be used in the workflow of radiation therapy. Adaptive AI algorithms are not within the scope of this product code. Primary radiation dose calculation or plan optimization for treatment planning are not within scope of this product code.
What these counts are not
Clearance and recall counts are SPEQ’s aggregation of FDA’s own published records for the code. A recall count is a measure of history, not of a device’s safety, neither number is an FDA rating, and SPEQ is not affiliated with the FDA.
What this classification requires
Every statement below is FDA’s own classification record for this product code, quoted from the device classification field reference. The SPEQ reading beneath each one is SPEQ’s interpretation of what it means for the work, and is not FDA text.
510(K)
SPEQ READINGA premarket notification under 21 CFR Part 807 Subpart E is the route for this code. The submission argues substantial equivalence to a legally marketed predicate, so the engineering question is which predicate the design can actually be compared against, and the evidence question is what testing supports that comparison.
Class II (moderate to high risk): general controls and special controls
SPEQ READINGSpecial controls are the distinguishing feature: performance standards, guidance documents, patient registries or postmarket surveillance named for the device type. Find the special controls before designing the test plan — they usually name the tests.
Device is not eligible for The Voluntary Malfunction Summary Reporting Program
SPEQ READINGIndividual malfunction reporting under 21 CFR Part 803 applies. The complaint-handling system has to produce a decision per event, not per period.
Not exempt due to Good Manufacturing Practice (GMP)/Quality System
SPEQ READINGThe full Quality Management System Regulation (21 CFR 820, incorporating ISO 13485:2016) applies, and is what an FDA inspection of this device will be conducted against.
Device is not implantable
SPEQ READINGNo implant-specific expectations attach from the classification itself.
Device is not used for life sustaining purposes
SPEQ READINGNo life-sustaining designation attaches to this code.
Device is not a candidate for a third party review program
SPEQ READINGFDA reviews any premarket notification for this code directly.
Other product codes under 21 CFR 892.2050
One regulation usually governs several product codes. These share this code’s regulation, and therefore its classification basis.
21 CFR 892.2050 — Medical image management and processing system
The classification regulation for this product code, as published by the Office of the Federal Register. This is the regulation text itself — no SPEQ interpretation appears in it.
(a) Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.
(b) Classification. Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).
