I The segmentation of knee cartilage; II The superficial and deep layers of patella cartilage.
Note: PC = patella cartilage, TC = trochlea cartilage, LFC = lateral femoral cartilage, LTC = lateral tibial cartilage.
Fig 2.
The T1 rho pseudo color maps after 30 minutes rest(I), walking(II), running(III) and stair activity(IV) presented the color of cartilage in a range from green to yellow for the superficial layer and from yellow to red in the deep layer.
