Abstract
Disclosed is a probe for an ultrasonic diagnostic apparatus with an improved heat-radiation structure using graphene. The probe includes a case to form an exterior appearance, a piezoelectric layer provided in the case to generate ultrasonic waves, a backing layer provided at the rear of the piezoelectric layer to prevent the ultrasonic waves from being transmitted backward from the piezoelectric layer, and a heat-radiation unit to radiate heat transmitted from the piezoelectric layer to the outside the case. The heat-radiation unit includes graphene. By attaching graphene having a high thermal conductivity to a heat source of the probe, a surface temperature of the heat source is reduced.
