Claim Text:
1. An ultrasound diagnostic apparatus comprising: a processor configured to: generate first physical quantity data for a first plurality of frames by calculating a physical quantity related to elasticity of parts in a living tissue based on an echo signal obtained by transmission and reception of an ultrasound wave to and from the living tissue, where the first plurality of frames is within a first predetermined time period having a length including a plurality of heartbeats; cumulatively add the first physical quantity data for the first plurality of frames, wherein the cumulative addition is an operation completed within the first predetermined time period, where the cumulative addition results in the generation of a first cumulative addition value, and wherein the first physical quantity data as an object of the cumulative addition is data satisfying a first predetermined reference that is set based on a value of the first physical quantity data measured during one of the plurality of predetermined time periods; and generate first elasticity image data based on the first cumulative addition value, wherein the elasticity image data includes information indicative of a display form corresponding to the physical quantity; generate second physical quantity data for a second plurality of frames by calculating the physical quantity related to elasticity of parts in a living tissue based on an echo signal obtained by transmission and reception of an ultrasound wave to and from the living tissue, where the second plurality of frames is within a second predetermined time period having a length that is the same as the first predetermined time period; cumulatively add the second physical quantity data for the second plurality of frames, wherein the cumulative addition is an operation completed within the second predetermined time period, where the cumulative addition of the second physical quantity data results in the generation of a second cumulative addition value, and where the second cumulative addition value does not include any of the first physical quantity data, and wherein the second physical quantity data as an object of the cumulative addition of the second physical quantity data is data satisfying a second predetermined reference that is set based on a value of either the first physical quantity data or the second physical quantity data; generate second elasticity image data based on the second cumulative addition value for the second plurality of frames, wherein the elasticity image data includes information indicative of a display form corresponding to the physical quantity; a monitor to display the first elasticity image and the second elasticity image.
