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.
