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.

According to an embodiment, a transmitter transmits a reference signal. A position sensor obtains position information in a three-dimensional space by receiving the reference signal. A controlling unit associates three-dimensional image data generated by a medical image diagnosis apparatus with the three-dimensional space, on the basis of a registration between an arbitrary cross-sectional plane in the three-dimensional image data and a cross-sectional plane scanned by an ultrasound probe. A detecting unit detects if the position of the transmitter has changed within the associated three-dimensional space, on the basis of the position information obtained by the position sensor. A correcting unit corrects a misregistration between a cross-sectional plane in the three-dimensional image data and a cross-sectional plane scanned by the ultrasound probe, on the basis of a change amount of the position of the transmitter.

An ultrasound diagnosis apparatus according to an embodiment includes a parameter setting unit, a Fly Thru image generating unit, and a controlling unit. The parameter setting unit sets a value of an image quality adjusting parameter used for generating a PVR image obtained by projecting the inside of a lumen from a predetermined viewpoint, on the basis of information about the lumen rendered in an MPR image generated by using volume data. The Fly Thru image generating unit generates the PVR image by using the value of the image quality adjusting parameter that was set. The controlling unit then causes a monitor to display the PVR image.

In quantitative analysis using blood flow velocity measurement and the like, whether to select the forward direction or reverse direction is determined in accordance with the positional relationship between a baseline for controlling the display scale of a Doppler waveform and a reference line which can be arbitrarily set by an operator. The determination is executed at one of the stages of selecting a tracing direction by an automatic tracing process, selecting an approximate Doppler waveform as an analysis target, and selecting an analysis result as a display target.

An imaging part acquires a plurality of ultrasound image data by sequentially imaging the subject with ultrasound waves. A display controller causes a display to display, side by side, a plurality of ultrasound images based on the plurality of ultrasound image data acquired by the imaging part. Moreover, the display controller causes the display to display measurement markers for obtaining quantitative information of tissues shown in the ultrasound images in a state superimposed in relatively the same positions on the plurality of ultrasound images.

A region-of-interest setting unit sets a region of interest to be included in an ultrasound image. A first movement-amount calculating unit sequentially calculates a movement amount of the set region of interest between reception data along the time sequence as a first movement amount. A transmitting-receiving delay-amount computing unit computes a delay amount for sequentially shifting a scan region of an ultrasonic beam based on the sequentially calculated first movement amount. A computation/control circuit performs control so as to generate a high voltage pulse based on the computed delay amount. A second movement-amount calculating unit sequentially calculates a movement amount of the region of interest between image data along the time sequence as a second movement amount. A display-position correcting unit performs a correction such that the region of interest included in the image data is to be displayed at the same display position, based on the second movement amount.

The display is configured to display the processed first part and the others of the display information.

An event signal is generated in response to a specific event as a trigger. A recording control unit controls the operation of an image recording unit on the basis of the event signal, thereby automatically forming, as a unit, and recording moving image information based on a unified standard. In addition, an event signal is generated in response to a specific event as a trigger. On the basis of ultrasonic image data of a frame corresponding to the event signal generation, a representative image as an index for search is automatically generated and recorded in association with the ultrasonic image data of the corresponding frame. Furthermore, the recorded representative image is read out and set on the screen. The ultrasonic image data is reproduced on the basis of the frame associated with the representative image selected by the operator.

At a measuring time, when at least one desired measurement category is selected from among a plurality of measurement categories associated with an ultrasonic image, at least one measurement item is selected from among a plurality of measurement items under the selected measurement category. Measurements corresponding to the selected measurement items are made sequentially. A title of those selected measurement items is inserted in a report. Since the title of those not-selected measurement items is not inserted in the report, there never occurs a situation in which the actually measured items and measurement results are buried in a vast number of measurement items, making it difficult to find them. That is, it is possible to minimize the number of pages and, by doing so, easily review the full actual measurement items one at a time on one screen or on one page and simply do this while being scrolled fewer times on a display screen or eye-scanning the pages of the report as required.
