ImageBiopsy Lab
Knee Osteoarthritis Labeling Assistant. Osteoarthritis is a paralyzing joint disease that can lead to joint replacement. Early detection as well as therapy can prevent unnecessary surgeries. Image Biopsy's lab module KOALA detects signs of knee osteoarthritis based on standard joint parameters and OARSI criteria of standing radiographs of the knee.

Intended Use Statements
Intended use (according to CE) IB Lab KOALA uses deep learning technology for detecting radiographic signs of knee osteoarthritis and augments the reporting workflow. The system is to be used by trained medical professionals including, but not limited to, orthopedists and radiologists. It should not be used in-lieu of full patient evaluation or solely relied upon to make or confirm a diagnosis.
