摘要:
An ultrasonic diagnostic apparatus according to the present invention is an apparatus to which a probe with transducers is connectible. The apparatus includes a controller 100 which performs transmission processing for sending out an ultrasonic wave toward a subject by driving the probe 1 and reception processing for generating a received signal based on the ultrasonic wave that has been reflected from the subject and received at the probe and which performs, if a predetermined condition based on the received signal is satisfied, automatic freeze processing for stopping at least one of the transmission processing and the reception processing. The controller 100 restricts the automatic freeze processing for a predetermined period of time after having accepted a predetermined operating event.

An ultrasonograph of the present invention comprises a probe (1), a controller (3) connected to the probe (1), and a display (4) connected to the controller (3). The controller (4) causes the display (4) to display a detected image of a target object detected by the probe (1) 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.

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.

The present invention provides a method for detecting lumen and adventitia boundaries and measuring an intima-media thickness without depending on the magnitudes of echo intensity variations on the lumen and adventitia sides.The ultrasonic diagnostic apparatus transmits an ultrasonic wave toward a body and obtains biological information based on an echo signal received and includes: an intensity distribution generating section that generates an echo intensity distribution in a depth direction about a vascular wall based on the echo signal; a template generating section that generates a template to detect a boundary based on template data provided in advance to represent a reference pattern of the intensity distribution; a pattern similarity calculating section that changes the depth and intima-media thickness pattern of the template to calculate similarity between the template and the intensity distribution on any change made; and a boundary defining section that defines lumen and adventitia boundaries based on the degree of similarity calculated on any change made.

An ultrasonic diagnostic apparatus transmits an ultrasonic wave toward a body and obtains biological information based on an echo signal received and includes: an intensity distribution generating section that generates an echo intensity distribution in a depth direction about a vascular wall based on the echo signal; a template generating section that generates a template to detect a boundary based on template data provided in advance to represent a reference pattern of the intensity distribution; a pattern similarity calculating section that changes the depth and intima-media thickness pattern of the template to calculate similarity between the template and the intensity distribution on any change made; and a boundary defining section that defines lumen and adventitia boundaries based on the degree of similarity calculated on any change made. The intima-media thickness is thus determined without depending on the magnitudes of echo intensity variations on the lumen and adventitia sides.

An ultrasonic diagnostic apparatus includes a controller, to which a probe and a monitor are connected, the probe having an array of transducers, in which a number of transducers are arranged in a first direction. The controller controls transmission of an ultrasonic beam using the array of transducers and reception of an echo signal reflected from a region of interest, generates image data based on the echo signal, and gets echo signals received from multiple points of the region of interest by either moving or swinging the array of transducers in a second direction that intersects with the first direction at right angles. If the sum of image data ranges of measured value retrievable portions of the region of interest at the multiple points synthesized based on the echo signals, is equal to or greater than a predetermined value, the controller calculates a detected value of the region of interest.
