DEVICE, SYSTEM, AND METHOD FOR COMBINED OPTICAL AND THERMOGRAPHIC DETECTION OF THE CONDITION OFJOINTS
First Claim
1. Device for optical detection of the condition of a joint, the device comprising:
- an optical measurement unit (4, 5) for irradiating a subject'"'"'s body part, the body part comprising at least one joint, with light and locally detecting attenuation of the light at the at least one joint and at least one other portion of the body part;
a thermographic measurement unit (3) for thermographically imaging the subject'"'"'s body part comprising the at least one joint;
a control unit (9) for controlling the device such that data obtained by one of the optical measurement unit (4, 5) and the thermographic measurement unit (3) is used to calibrate data obtained by the other of the optical measurement unit (4, 5) and the thermographic measurement unit (3).

6. Detection method comprising the following steps:
-
optically imaging (40) a subject'"'"'s body part comprising at least one joint, the optical imaging comprising the steps of; irradiating the subject'"'"'s body part comprising the at least one joint with light; detecting local attenuation of the light by the body part at the position of the at least one joint and at the position of at least one other portion of the body part; thermographically imaging (45) the body part; calibrating data (50) obtained in one of the steps of optically imaging a subject'"'"'s body part and thermographically imaging the body part using data obtained in the other of the steps of optically imaging a subject'"'"'s body part and thermographically imaging the body part. - View Dependent Claims (7, 8, 9, 10, 11)
