Patent ID: 7871379

Claim:
An ultrasonic diagnostic apparatus, comprising: an ultrasonic probe having ultrasonic transducers configured to transmit and receive ultrasound in a direction of an object to be examined; a transmission/reception unit configured to drive the ultrasonic transducers to transmit the ultrasound and receive reflected signals from the object; a data generation unit configured to generate ultrasonic data by processing the received reflected signals obtained by the transmission/reception unit; an image/time-series data generation unit configured to generate image data and time-series data by processing the ultrasonic data obtained by the data generation unit; a display mode switching unit configured to input a display mode switching signal for switching a dynamic image display mode and a freeze image display mode; a display format selection unit configured to allow an operator to select a first display format for the dynamic image display mode and a second display format for the freeze image display mode; a memory circuit to store the first display format for displaying the image data and the time-series data and the second display format for displaying the image data and the time series data; a display format setting unit configured to set the first or the second display format by reading stored data of the first or the second display formats from the memory circuit; a display data generation unit configured to generate display data based on the first display format when the dynamic image display mode is selected corresponding to the display mode switching signal, and to generate display data based on the second display format when the freeze image display mode is selected corresponding to the display mode switching signal; and a display unit configured to display the display data, wherein the first and the second display formats stored in the memory circuit are automatically selected to display the display data in the set format using the display data generation unit according to the display mode switching signal provided from the display mode switching unit.
