Intended Use Statements
Intended use (according to CE) IB Lab LAMA is a radiological fully-automated image processing software device of either computed (CR) or directly digital (DX) images intended to aid medical professionals in the measurement of lower limbgeometry, assessment of leg alignment and leg length difference. 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.
