Abstract: A transmission and reception control unit controls transmission of an ultrasonic wave toward a blood vessel and reception of a reflected wave. A setting unit sets a signal range including a signal part for tracking movement of blood vessel walls of the blood vessel due to pulsation, and a signal waveform template in the signal range, among received signals of the reflected waves obtained at a first timing. Then, a detection unit detects a second timing when a signal waveform of the signal part corresponding to the signal range among the received signals and the signal waveform template satisfy predetermined equivalent conditions. A tracking unit starts tracking at the second timing.

Abstract: In an ultrasonic measuring apparatus, an addition/averaging-period setting unit determines a blood vessel diameter stable period in which a blood vessel diameter is in a stable state in one heartbeat period and sets the blood vessel diameter stable period as an addition and averaging period. An adding and averaging unit adds up and averages reflected wave measurement data measured in the addition and averaging period set by the addition/averaging-period setting unit. A blood-vessel-diameter calculating unit calculates a blood vessel inner diameter of a blood vessel using combined data obtained by the addition and averaging of the adding and averaging unit.

Abstract: In an ultrasonic blood pressure meter 1, changes in blood pressure in a peripheral artery measured by a blood pressure meter 2 are input from an input unit 40.
