Abstract: An ultrasonographic device is equipped with selecting means for selecting a site for detecting the position of a boundary of an organ of the examinee on the ultrasonic image displayed on the display means, boundary extracting filter setting means for setting a boundary extracting filter comprising two areas which are spaced from each other at a predetermined interval on the ultrasonic image, and boundary position detecting means for analyzing pixel data within the boundary extracting filter set by the boundary extracting filter setting means in the neighborhood of the site selected by the selecting means to detect the position of the boundary, the boundary position detected by the boundary position detecting means being displayed on the display means under the control of the control means.

Abstract: A medical diagnostic imaging apparatus is provided that is capable of accurately tracking motions of a moving organ that moves periodically over a plurality of periods. The medical diagnostic imaging apparatus includes a matching computation unit for performing a matching computation between a template extracted containing a tracking point on one image and another image, and a template extracting unit for extracting, from the other image, a region correlated with the template as a template of the other image by the matching computation, whereby a movement of the tracking point is tracked based on the extracted template. The template extracting unit extracts, as a key template, a region containing one or more tracking points set on an image at least one time phase within a motion cycle of the moving organ. The matching computation unit performs the matching computation using the key template in the vicinity of the time phase at which the key template is extracted.

Abstract: [Objective] Providing a medical image diagnostic apparatus which can mitigate an operational burden at the time when measurement processing is performed by use of a medical image. [Means for Solution] An ultrasonic diagnostic apparatus 100 acquires input image information, which is image data of a subject, and holds it in a storage section 3. An image selection section 8 performs image recognition calculation for comparison between the input image information and past image information pieces of an image measurement database 7. When the image recognition has succeeded, a measurement-position setting section 9 refers to a record of image measurement information including a past image information piece most similar to the input image information, retrieves measurement position information of the record, and sets it. A measurement-position setting processing section 6 displays the measurement position on a display section 12 such that it is superimposed on the input image information 21.
