Abstract
Provided is an ultrasonograph and the like capable of easily specifying defective parts of an ultrasound probe and appropriately treating the defective parts. A test method of an operation of an ultrasound probe that transmits and receives a signal of ultrasound for creating a diagnostic image in an ultrasonograph includes: bringing a test material into contact with the ultrasound probe and transmitting a first ultrasound from the ultrasound probe to the test material by a first transmitting circuit connected to the ultrasound probe; receiving, by a first receiving circuit connected to the ultrasound probe, a received signal of a reflected wave of the first ultrasound received by the test material and receiving, by a second receiving circuit connected to the test material, a received signal of the first ultrasound received by the test material; and comparing the received signals with each normal received signal stored in a memory and determining whether the operation of the ultrasound probe is normal or defective based on the comparison result.
