PROBLEM TO BE SOLVED: To alleviate the burden of resetting a FOV imposed on an operator. SOLUTION: When the position and size of an ROI is changed, when a CFM image is displayed on the ROI set on a B-mode image is displayed, the depth of the FOV is automatically adjusted to ensure that a depth obtained by adding a prescribed space to the lowermost portion of the ROI after change is the FOV of the B-mode image B. The burden imposed on an operator can be reduced. Deterioration of the real-time property due to scanning with FOV kept unnecessarily deep is prevented. The position of the ROI can be moved to below the deepest part of the current FOV and the size of the ROI can be expanded. |
