ABSTRACT:
A diagnostic ultrasound apparatus includes an ultrasound probe for transmitting and receiving ultrasound beams to and from an object to be observed; a frame memory for storing B-mode ultrasound image data of the object obtained from the ultrasound beams received by the ultrasound probe; a monitor for displaying at least a B-mode ultrasound image of the object formed on the basis of the B-mode ultrasound image data stored in the frame memory; a sampling line setting circuit for freely setting a desired course and range of at least one data sampling line for the B-mode image displayed on the monitor; and a read-out circuit for selectively reading out, from the ultrasound image data stored in the frame memory, ultrasound image data corresponding to the data sampling line. The ultrasound image data which has been read out by the read-out circuit is displayed on the monitor as an M-mode image. According to the diagnostic ultrasound apparatus, the data sampling line is established for any desired course and range unrelated to the forward direction of the ultrasound beams which form the B-mode image displayed on the monitor, and the ultrasound image data which corresponds to the data sampling line is selectively read out from the ultrasound image data of the B-mode image stored in the frame memory. The thus-obtained ultrasound image data of the data sampling line of the desired course, that is the M-mode image is displayed on the monitor. Therefore, observation and diagnosis of the state of motion of any specific part of the patient can be carried out freely in any direction irrespective of the forward direction of the ultrasound beams from the probe.
