Embodiment Construction

[0022] figure 1 An embodiment of the device according to the invention is shown schematically. In this illustration, a human body 6 is shown schematically as a body, and the hand forms the body part to be examined. It should be noted, however, that the present invention is not limited to human bodies, and, for example, animal bodies may be subjected to examination. Furthermore, the body part is not limited to a hand, but may also be formed by another body part (such as an arm, a leg, a foot, etc.) comprising at least one joint.

[0023] In the illustrated embodiment, the device for optical detection of joint conditions comprises a thermal imaging measurement unit 3 , optical measurement units 4 , 5 , a blood flow obstruction unit 8 and a control unit 9 . A control unit 9 is provided for controlling the operation of the device and data acquisition. Optical measurement units 4, 5 are provided for illuminating the parts of the examined body part with light and measuring the l...

Abstract

The invention relates to a device, system and method for optical detection of the condition of a joint. The invention involves: an optical measurement unit (4, 5) for irradiating a subject's 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).

Description

technical field [0001] The invention relates to an optical detection method and to a device for optical detection of joint conditions. Background technique [0002] In the context of the present application, the term light is understood to mean non-ionizing electromagnetic radiation, in particular whose wavelength range is between 400 nm and 1400 nm. The term body part means a part of a human or animal body. The term blocking covers completely blocking and largely blocking. [0003] The present invention relates generally to the optical detection of joint conditions, and in particular to the optical detection of joint diseases such as rheumatoid arthritis (RA). Treatment for this joint disorder is staged. Usually, patients receive pain medication first. These are often followed by nonsteroidal anti-inflammatory drugs (NSAIDs) and disease-modifying antirheumatic drugs (DMARDs). In many cases, the final stage of medical treatment is the use of biologic therapy. In partic...
