Systems and methods for creating and using intravascular ultrasound system with a photoacoustic imaging function

摘要

The catheter assembly of intravascular ultrasound system includes a (306) imaging core disposed within the catheter (102) and catheter. (310), one light source, and an imaging core comprises a (312) at least one transducer at least a rotatable drive shaft. At least one light source is disposed at the distal end of the rotatable drive shaft at least. One light source so as to rotate with the drive shaft, and is constructed and arranged addition and, to irradiate the object in the vicinity of the catheter by converting electricity into light signals which are applied at least. It is disposed at the distal end of the rotatable drive shaft is also at least one transducer. One transducer is constructed and arranged to rotate with the drive shaft at least. One transducer is constructed and arranged to receive an acoustic signal generated by the target in response to the irradiation of a subject with the light emitted from the at least one light source, at least.
