Assignee: KONICA MINOLTA, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 2:
3. The ultrasonic diagnostic apparatus according to claim 1, wherein
the digital arithmetic circuit includes:
an encoder counter that receives the detection signal as an input and performs count processing for each rise or fall of the pulse of the detection signal;
a microstep counter that receives the drive signal as an input and performs count processing for each rise or fall of the microstep of the drive signal to output the number of microsteps of the drive signal;
a position data converter that converts an encoder count value output from the encoder counter into a count value with a target resolution of the high-resolution position data as a reference by referring to a predetermined conversion table; and
a position data interpolation processor that generates the high-resolution position data on a basis of the encoder count value after conversion and the number of microsteps of the drive signal output from the microstep counter.
