Abstract: An ultrasound diagnostic apparatus performs transmission and reception of ultrasonic waves for forming focal points used to set sound velocities at predetermined timing such that sound velocities having been set for all of respective segment regions established by diving a subject are all reset every predetermined number of frames. Owing to this configuration, it becomes possible for the ultrasound diagnostic apparatus to suitably reset sound velocities of ultrasonic waves in the subject and also reduce the amount of calculation for resetting sound velocities.

Abstract: First to fourth narrow band light N1 to N4 is sequentially applied to an observation object by rotating a rotary filter for special observation set in an optical path of a broad band light source. A blood vessel enhanced image in which a superficial blood vessel and a middle to deep-layer blood vessel are enhanced is produced based on reflection images of the first and fourth narrow band light N1 and N4. An oxygen saturation image, which images an oxygen saturation level of hemoglobin in blood, is produced based on reflection images of the second to fourth narrow band light N2 to N4. The produced blood vessel enhanced image and the oxygen saturation image are displayed side by side on a monitor.
