Ultrasonic diagnosis apparatus and image display method

An image display method for displaying a cross-section region image and an elasticity image, the method comprising:

• analyzing temporal variation at respective measurement points from elasticity information indicating hardness;
• constituting a temporal variation image based on the temporal variation;
• constituting the temporal variation image for a measurement point at which the temporal variation is greater than a threshold and does not constitute the temporal variation image for a measurement point at which the temporal variation is smaller than the threshold;
• and
• displaying the temporal variation image.

An ultrasonic diagnosis apparatus comprising:

• a cross-section region image constituting unit, executed by a processor, to constitute a cross-section region image of a diagnosis portion of a diagnosing object through an ultrasound probe;
• an elasticity information calculator that calculates elasticity information indicating hardness;
• an elasticity image constituting unit, executed by a processor, to constitute an elasticity image based on the elasticity information calculated at the elasticity information calculator;
• an image display that displays the cross-section region image and the elasticity image;
• a temporal variation analyzing unit, executed by a processor, to analyze temporal variation at respective measurement points from the elasticity information calculated at the elasticity information calculator;
• a temporal variation image constituting unit, executed by a processor, to constitute a temporal variation image based on the temporal variation analyzed at the temporal variation constituting unit,
• wherein a first region of interest and a second region of interest are set in advance, and, when the temporal variation image constituted by the temporal variation image constituting unit is superimposed on the first region of interest and the second region of interest, the elasticity information calculator does not calculate an index value of the elasticity information in the first region of interest and the second region of interest, and
• wherein the image display displays the temporal variation image.
