PROBE CONTROL APPARATUS, NON-TRANSITORY COMPUTER READABLE MEDIUM, AND ULTRASOUND DIAGNOSTIC APPARATUS
According to one embodiment, a probe control apparatus includes processing circuitry. With respect to a scanning line in which a change has been made to a depth of field, the processing circuitry makes a change to a pulse repetition frequency in accordance with the depth of field after the change. The processing circuitry sets a new transmission voltage based on the pulse repetition frequency after the change.
1 . A probe control apparatus comprising processing circuitry configured to:
with respect to a scanning line in which a change has been made to a depth of field, make a change to a pulse repetition frequency in accordance with the depth of field after the change; and
set a new transmission voltage based on the pulse repetition frequency after the change.
2 . The probe control apparatus according to claim 1 , wherein the processing circuitry sets, as the new transmission voltage, a value obtained by multiplying a transmission voltage with the pulse repetition frequency before the change by a square root of a ratio of the pulse repetition frequency before the change to the pulse repetition frequency after the change.
3 . The probe control apparatus according to claim 1 , wherein the processing circuitry sets the new transmission voltage in such a manner that heat generation caused by transmission of an ultrasound beam becomes equal to or less than an allowable value.
4 . A non-transitory computer readable medium including computer executable instructions, wherein the instructions, when executed by a processor, cause the processor to perform a method comprising:
with respect to a scanning line in which a change has been made to a depth of field, making a change to a pulse repetition frequency in accordance with the depth of field after the change; and
