Device Classification

Product Code QKB Radiological Image Processing Software For Radiation Therapy
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 892.2050
Definition 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 this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Radiology devices follow this clearance model.
