Medical image diagnostic apparatus and volume calculating method

摘要

A medical image diagnostic apparatus provided with an image acquisition unit configured to acquire in-vivo information about an object to be examined as a medical image, a display unit configured to display the medical image, a setting unit configured to set a target region of volume measurement in the medial image displayed on the display unit, a calculation unit configured to perform calculation to split the target region into a plurality of volume elements, calculate the moving distance of the vertices of the volume elements when the target region of the acquired medical image moves, calculate the volumes of the volume elements after the movement using the calculated moving distance of the vertices, totalizing the calculated volumes of the volume elements after the movement and using the total volume as the volume of the target region, and a control unit configured to display the volume of the target region on the display unit.

1. A medical image diagnostic apparatus comprising:
an image acquisition unit configured to acquire in-vivo information of an object to be examined as a medical image; a display unit configured to display the medical image; a setting unit configured to set a target region for volume measurement in the medical image displayed on the display unit; a calculation unit configured to perform a calculation to split the target region into a plurality of volume elements, calculate a moving distance of the vertices of the plurality of volume elements caused by the movement of the target region in the acquired medical image, calculate a volume of the plurality of volume elements after the movement using the calculated moving distance of the vertices, sum the calculated volumes of the plurality of volume elements after the movement, and set the summed volumes as the volume of the target region; and a control unit configured to cause the display unit to display the volume of the target region, wherein the plurality of volume elements split by the calculation unit comprises a first volume element, which is disposed on the outer side of a cardiac chamber of a heart, and a second volume element, which is disposed on the inner side of the cardiac chamber of the heart, wherein the image acquisition unit acquires in-vivo information of the object as a medical image in time series, and wherein the calculation unit calculates the moving distance of the vertices of the plurality of volume elements in time series, calculates volume of the plurality of volume elements in time series based on the moving distance of the vertices, and sums the calculated volumes of the plurality of volume elements in time series.
