Classification: CPC A  G | IPC A  G

Claim 0:
1. A handheld ultrasound and nuclear medicine fusion imaging device, comprising:
a transducer to transmit an ultrasound beam and receive a reflected beam;
a matching layer disposed on a first surface of the transducer to reduce a difference in acoustic resistance between the transducer and an affected part, to support the ultrasound beam to be transmitted into tissues and the reflected beam to be received;
an absorber comprising a first backing material disposed on a second surface of the transducer opposite to the first surface;
wherein the first backing material comprises epoxy and tungsten
a transmission layer disposed on the second surface comprising air or a second backing material having a lower density than the first backing material to transmit the gamma rays; and
a scintillator disposed on the transmission layer to detect gamma rays which are generated in the affected part and transmitted through the transducer and the matching layer,
wherein a lateral surface of the scintillator and the transmission layer are surrounded by the absorber, and
wherein the absorber serves as an acoustic absorber and as a collimator of the handheld ultrasound and nuclear medicine fusion imaging device, thereby absorbing the ultrasound beam transmitted in a direction from the first surface to the second surface and attenuating the gamma rays coming from an unwanted direction.
