Device and method of imaging a limb, such as an arm or leg, by scanning using both an optical camera and an ultrasound sensor, where the devices are electronically or mechanically linked such they both scan a portion of the limb, and the images displayed from the two sensors are visually aligned. Scanning may be in one or both of the longitudinal plane and the axis of the limb, such that most of the surface of the limb may be imaged. Stitched images from the sensors are visually aligned relative to the anatomical features of the limb. The limb is placed in a receptacle, typically with an open top, containing a transparent fluid through which both sensors operate. Either the sensors move (scan) relative to the fixed receptacle or the receptacle rotates, such as on a turntable.
