Blood Vessel Visualization using a Micromotor Type IVUS

Md. Salimuzzaman (9551124)

The objective of the present study is to develop a new intravascular ultrasound (IVUS) endoscope using a micromotor, in which ultrasound beam is scanned radially by a micromotor instead of a rotation transmitting wire. In this micromotor type IVUS endoscope, a micromotor attached with an ultrasound reflecting mirror and an ultrasound transducer are inserted in a catheter. The rotation of the micromotor is performed and controlled by an external magnetic field. This micromotor type IVUS endoscope was applied to observe the inside of blood vessels through in vitro experiments. The preliminary results suggested that a micromotor type IVUS has sufficient ability to define the blood vessel morphology precisely and can solve the problems of conventional IVUS endoscopes.
