Patent ID: 7778683

Claim:
A blood rheology measurement device comprising: detecting means having a sensor unit including an ultrasonic wave sensor section which transmits and receives an ultrasonic wave between the surface of a living body and an artery blood flow in the living body, and an image pickup section which picks up an image of the living body from the living body surface; image processing means having an image processing section which processes the image obtained by the image pickup section; an image database which stores the image processed by the image processing means; and blood rheology measuring means for processing a signal output from the ultrasonic wave sensor section to measure a fluidity of the artery blood flow in association with the image processed by the image processing means, wherein the detecting means further comprises a driving mechanism which moves a position of the sensor unit, the image processing means comprises a database collating section which collates the processed image output from the image processing section with the image stored in the image database and corresponding to the processed image; and a sensor unit moving circuit which controls the driving mechanism to move the position of the sensor unit so that the processed image and the stored image collated by the database collating section overlap with each other.
