Claim Text:
1. An optical tomography imaging system for detecting peripheral artery disease, comprising: an external body part stimulator; a controller controlling the external body part stimulator, the external body part stimulator applying a mechanical stimulus to a target body part to be inspected; and an interlacing module arranged to image a peripheral body part of the body part using a plurality of light sources and a plurality of light detectors, wherein the controller: controls each of the plurality of light sources to emit light sequentially such that light is transmitted through the body part and transmitted light is detected by the plurality of light detectors, applies a first mechanical stimulus while acquiring a first series of time separated data from the light detected by the light detectors and later applies a second mechanical stimulus while acquiring a second series of time separated data from the light detected by the light detectors, generates a first three-dimensional cross sectional tomographic image of the body part responsive to the first series of time separated data, and generates a second three-dimensional cross sectional tomographic image of the body part responsive to the second series of time separated data, and generates and displays visual representations derived from the first three-dimensional cross sectional tomographic image and the second three-dimensional cross sectional tomographic image, thereby displaying a representation of a differential response of the body part to the first and second mechanical stimuli, wherein the interfacing module includes a member shaped to enclose a portion of the body part, the interfacing module being adjustable in axial and radial dimensions, wherein the plurality of light sources and the plurality of light detectors are positioned on the member in a plurality of rows, each row encircling the portion of the body part, and each row being independently movable along vertical and radial directions, and wherein the plurality of light sources and the plurality of light detectors are detachably attached to the member so as to be positioned around the portion of the body part, the interfacing module further including connecting members connecting the rows to each other so as to allow the rows to be moved relative to each other by changing the mutual spacing of the rows and thereby to permit the interfacing module to inspect different portions of the body part and to permit different sized body parts to be accommodated thereby.
