"I was lucky to trial PhysisTM early on when working with one of its developers. Right from the start, I've found it simple to use, quick and surprisingly accurate when I compare it with my usual calculation, having read bone age x-rays for 20+ years."

PhysisTM is a convenient and reliable method to rapidly assess a patient’s bone age at the point of care.  I used to flick back and forth through the Gruelich and Pyle atlas until I found an image that matched the patients X-ray, but now I can get an answer I know is accurate within a few seconds.
