Abstract
This invention realizes high diagnosis efficiency in ultrasonic diagnosis. A start frame selecting unit selects a start frame corresponding to the time a display unit starts displaying slice images in chronological order, in slice images in a plurality of frames generated in chronological order by an image generating unit. The start frame selecting unit selects the start frame in accordance with time point when an injection time counting unit starts counting the time of injecting a contrast medium into the subject. The display unit sequentially displays the slice image of the start frame selected by the start frame selecting unit and the subsequent slice images of the frames generated in chronological order by the image generating unit.
Claims15
An ultrasonic diagnostic apparatus comprising:
- a scanning device for obtaining echo signals by performing a scan of transmitting ultrasonic waves to a subject into which a contrast medium is injected and receiving the ultrasonic waves reflected from the subject to which the ultrasonic waves were transmitted;
- an image generating device for generating slice images of the subject in a plurality of frames in chronological order on the basis of the echo signals obtained by the scanning device;
- a storing device for storing the slice images in the plurality of frames generated by the image generating device;
- and
- a display device for sequentially displaying the slice images in the plurality of frames stored in the storing device so as to correspond to the chronological order in which the image generating device has generated the plurality of frames,
- wherein the apparatus comprises:
- a start frame selecting device for selecting a start frame at the time the display device starts displaying the slice images in the chronological order from the slice images in the plurality of frames generated in the chronological order by the image generating device;
- and
- an injection time counting device for counting time in which the contrast medium is injected into the subject,
- the start frame selecting device selects, as the start frame, a frame generated by the image generating device when the injection time counting device starts counting the time in which the contrast medium is injected into the subject, and
- the display device sequentially displays the slice image of the start frame selected by the start frame selecting device and the subsequent slice images in the frames generated in the chronological order by the image generating device.
