First Claim
Patent Images
1. An optical tomography device for imaging at least one finger of a patient, the device comprising:
- a detection portion with a support configured to permit the hand of a person to rest thereon, the support being attached to a frame for an illuminating device configured to illuminate joint portions of the hand at a plurality of locations thereof;
an imaging portion configured to image light emanating from the hand of the person which results from the illumination at the plurality of the points and to generate image data representative of the light emanating from the hand, the points being surface locations and being at different positions on the surface of the hand;
a processor programmed to receive the image signals and combine the image data representing light emanating from the hand in response to each of the plurality of points;
the processor being further programmed to estimate a distribution of an optical property within the hand by combining the image data corresponding to at least two of the plurality of points.

Abstract
Joint imaging devices methods and systems provide multiple sources and detectors around small accessible joints, such as fingers, to permit optical tomographic image acquisition and diagnosis of medical conditions such as rheumatoid arthritis. In embodiments, transducers permit convenient arrangement of sources and detectors and the rapid acquisition of anatomical surface geometry.
