    摘要: An ultrasonic diagnostic apparatus includes a transmission unit that transmits at least one ultrasonic pulse from a surface of a skin of a subject toward a blood vessel (21) thereof, a reception unit (3) that receives an ultrasonic echo reflected by the blood vessel and converts the same into an electric signal to obtain a signal of the ultrasonic echo along a depth direction from the surface of the skin, a movement detection unit (5) that analyzes a phase of the ultrasonic echo signal in a direction traversing the blood vessel so as to calculate a movement amount in each of a plurality of parts included in a blood vessel wall constituting the blood vessel and a vicinity of the blood vessel wall, and a boundary detection unit (7) that detects a boundary position between the blood vessel wall and a blood flow region (22) in a lumen of the blood vessel through which blood flows based on a variation in the calculated movement amount in each part. Instability occurring when a brightness signal in image data is used can be eliminated, so that a state of a blood vessel, such as an IMT value, can be measured correctly using ultrasonic waves.

    摘要: Embodiments of the present invention securely latch an actuator rotated by an external impact. In an embodiment of the present invention, a latch and an actuator have a structure in which the latch can latch the actuator at two different swing angles. The swing angle of the latch is an angle in rotation centered on a rotational shaft (rotation angle). The latch may be engaged with the actuator at a shallow angle, or the latch may be engaged with the actuator at a deeper angle. Since the latch is able to latch the actuator at different swing angles, the actuator can be securely latched.
