An ultrasonic diagnostic apparatus comprises an operation unit that arbitrarily specifies a cross-section a specified cross-section tomographic image constructing unit that cuts and constructs a tomographic image of the specified cross-section from tomographic volume data that is stored in the volume data storing unit a specified cross-section elastic image constructing unit that cuts and constructs an elastic image of the specified cross-section from elastic volume data that is stored in the volume data storing unit and a display unit that displays in parallel the tomographic image and the elastic image that are constructed by the specified cross-section tomographic image constructing unit and the specified cross-section elastic image constructing unit.
