An ultrasound diagnostic apparatus includes the following. A deflection controller generates delay time information to make phases of reception signals input to channels uniform according to a deflection angle. A channel selector selects a channel in which the reception signal is turned on or off so that the phases of the reception signals input to channels are different and which generates channel selection information. A reception delay interrupter provides the delay amount to the reception signal and which turns on or off the reception signal. An adder adds the plurality of reception signals which are provided with the delay amount and turned on.

Ultrasound diagnostic apparatus with electromagnetic noise suppression

An ultrasonograph that can automatically optimize the sweep rate of Doppler images and M-mode images according to the heart rate of a test subject. The ultrasonograph includes means for sending an ultrasonic beam into body tissue, a means for receiving an ultrasonic signal reflected off the body tissue and a blood flow, a means for constructing a cross-sectional image of the body tissue from the received signal, a means for performing phase detection on an ultrasonic Doppler blood flow signal, a means for calculating a frequency component of the Doppler blood flow signal, and a means for performing a sweeping display of the calculated frequency component as Doppler images in a time series. The ultrasonograph has a heart rate measuring means, an optimum sweep rate calculating means and an optimum sweep rate setting means.

Ultrasonograph

An ultrasonic diagnostic apparatus according to the present invention includes: an ultrasonic signal processing section, which performs transmission processing for transmitting an ultrasonic wave toward a subject's blood vessel by driving a probe and reception processing for generating a received signal based on the ultrasonic wave reflected from the subject's blood vessel and received at the probe; a tomographic image processing section, which generates a tomographic image based on the received signal; a boundary detecting section, which detects the lumen-intima and media-adventitia boundaries of the blood vessel based on the received signal or the tomographic image; a vascular wall thickness calculating section, which calculates, as a vascular wall thickness value, the interval between the lumen-intima and media-adventitia boundaries detected by the boundary detecting section; a reliability determining section, which determines the reliability of the vascular wall thickness value by a signal feature of the received signal or an image information feature of the tomographic image at a location on the lumen-intima and/or media-adventitia boundaries detected; and a control section, which decides, in accordance with the decision made by the reliability determining section, that the vascular wall thickness value be defined as an intima-media thickness.

Ultrasonic diagnostic device, and method for measuring initma-media complex thickness

An ultrasonograph of the present invention comprises a probe (), a controller () connected to the probe (), and a display () connected to the controller (). The controller () causes the display () to display a detected image of a target object detected by the probe () and an angular position relationship image showing a relative angular position of the probe to the detected image of the target object. This enables even a non-expert to take accurate measurements.

Ultrasonograph and method of diagnosis using same

An ultrasonic diagnostic apparatus is provided in which overlap of a displayed ultrasonic image and displayed diagnostic data can be avoided without imposing the burden of complicated operations on the operator. An ultrasonic diagnostic apparatus includes: an ultrasonic probe for transmitting an ultrasonic beam to a tissue of a biological body and receiving a reflection wave of the ultrasonic beam reflected from the tissue; an image construction section for constructing an image frame of a first image representing a tomographic image of the tissue based on the reflection wave; an image analysis section for distinguishing a region of no interest based on an image feature quantity of the image frame, the region of no interest constituting part of the image frame which is exclusive of a region of interest that includes the tomographic image of the tissue; a data generation section for generating a second image that is for display of diagnostic data; an image synthesis section for generating a synthesized image by determining a display position of the second image based on a result of the distinguishment by the image analysis section and superimposing the second image on the image frame of the first image; and a display section for displaying the synthesized image.
