An ultrasonic diagnostic apparatus according to the present embodiment includes an ultrasonic probe, image generation circuitry, acquisition circuitry, calculation circuitry, guide image generation circuitry, and control circuitry. The ultrasonic probe transmits ultrasonic waves, and receives reflected waves. The image generation circuitry generates cross-section image data based on the reflected waves. The acquisition circuitry acquires, from volume data corresponding to three-dimensional region containing a blood vessel inside the subject, cross-section position information corresponding to the cross-section image data. The calculation circuitry calculates collection position information in the volume data based on a running direction of a blood vessel contained in the volume data, the collection position information corresponding to a position from which blood flow velocity information is collected. The guide image generation circuitry generates guide image data based on the cross-section position information and the collection position information. The control circuitry causes the guide image data to be displayed.

Ultrasonic diagnostic apparatus

An ultrasonic diagnosis apparatus according to an embodiment includes a transmission unit, a reception unit, a generator, and a display controller. The transmission unit causes an ultrasonic probe to transmit a displacement-producing ultrasonic wave and causes the probe to transmit a displacement-observing ultrasonic wave. The reception unit generates reflected-wave data based on a reflected wave received by the probe. The generator calculates displacement at each of a plurality of positions in the scan area over a plurality of time phases, based on the reflected-wave data, determines a time phase when the calculated displacement is substantially maximum, for each of the positions, and generates image data representing positions where the determined time phases are substantially the same as each other, among the positions. The display controller superimposes an image based on the image data on a medical image corresponding to an area including the scan area.

A medical image diagnostic apparatus according to the embodiment includes a scanner, image generating circuitry, marker generating circuitry, and control circuitry. The scanner performs scanning to generate an image of the inside of a subject. The image generating circuitry generates an image based on the result of scanning performed by the scanner. The marker generating circuitry generates a marker provided with information at a position serving as a reference for comparison with a certain structure. The control circuitry displays the image and the marker on the same screen of a display.

Medical image diagnostic apparatus and medical image processing apparatus

According to one embodiment, an ultrasound image diagnosis apparatus includes a display and a control circuit. The display is configured to display an ultrasound image generated based on an echo signal of ultrasound waves transmitted to a site to be diagnosed. The control circuit is configured to measure a measurement target on the ultrasound image of the site to be diagnosed displayed on the display. The control circuit performs a definition function to define the distance between a caliper used to measure the measurement target and a guide used to arrange the caliper at the position of the measurement target, a display control function to control the display of the caliper and the guide arranged to be separated by the distance defined such that the caliper and the guide are integrally movable on the ultrasound image, and a measurement function to measure the measurement target using the caliper.

Ultrasound image diagnosis apparatus, medical image processing apparatus, and computer program product

According to one embodiment, an ultrasound diagnosis apparatus includes an acquisition unit, a selection unit, and a display control unit. The acquisition unit acquires a medical image accompanied by supplementary information indicating a site. The selection unit selects one of a plurality of instruction instruments each corresponding to a site. The display control unit displays the medical image, the instruction instrument, and an ultrasound image together on a display. Upon receipt of a change instruction to change either the instruction instrument or the medical image, the selection unit newly selects the medical image or the instruction instrument corresponding to the instruction instrument or the medical image after the change. The display control unit displays the instruction instrument or the medical image after the change, the medical image or the instruction instrument newly selected, and the ultrasound image together.

Ultrasound diagnosis apparatus, medical image processing apparatus, and medical image processing method

According to one embodiment, a position detection unit detects position information of an ultrasonic probe including ultrasonic transducers, with reference to a reference position. A transmission/reception unit supplies a driving signal to each transducer and generates a reception signal based on a reception echo signal generated by the transducer. Based on the reception signal, a three-dimensional data generation unit generates first three-dimensional data, in which a region corresponding to a living body tissue is specified by a specifying unit. A setting unit sets a first viewpoint based on the position information and specified region. An image generation unit generates a rendering image by rendering processing using the first viewpoint and first three-dimensional data.

A transmission and reception unit repeatedly scans a three-dimensional scanning area including a specific part of a patient with an ultrasonic beam via an ultrasonic probe. A volume data set generation unit generates a plurality of volume data sets whose scanning times different from one another in accordance with the output from the transmission and reception unit. A section image generation unit respectively generates the data of a plurality of the section images concerning the predetermined section of the specific part based on the plurality of the volume data sets. An image display unit displays the plurality of section images by changing at least one of the position and the size of each of the plurality of section images against the display area in accordance with variation of at least one of the position and the shape of the specific part on the plurality of section images.

A workflow representing an operation procedure is displayed on a monitor as a status window to notify a user of the operation procedure. The workflow is defined by a workflow protocol in which activities of an ultrasonic diagnostic apparatus for realizing operations associated with diagnosis are arranged in accordance with the operation procedure. Since each function of the ultrasonic diagnostic apparatus is controlled in accordance with the workflow protocol, the ultrasonic diagnostic apparatus can perform a diagnostic operation according to the workflow using the functions according to the workflow protocol.
