| Abstract: | The ocular normal blood circulation is the basis for maintaining the ocular tissue natural physiological function.This paper presents a kind of ocular Doppler ultrasound rheometer which can inspect the instantaneous relative change of the ocular blood velocity and the ocular blood circulation status without trauma.The ultrasound Doppler rheometer consists of ultrasonic generator,ultrasonic transducer,amplifier,single mixer,analog to digit(A/D) converter and personal computer and so on.Relative changes of the ocular blood velocity and volume can be measured in vivo and without trauma.The rheometer has the advantages of simple structure and easy operation. |
