摘要： A subject-side apparatus 10A is provided with a cine memory 15 for sequentially storing an ultrasonic signal that is received by an ultrasonic wave transmission/reception portion 12 per each frame. Every time after freezing when moving a pointer for designating a frame to be reproduced in a hospital-side apparatus 20A, a communication line interface 14 of the subject-side apparatus reproduces a frame that is required to be retransmitted by a console 24 of the hospital-side apparatus from the cine memory, and retransmits it to a communication line interface 21 of the hospital-side apparatus via a communication line 30. Then, an ultrasonic image of the retransmitted frame is displayed on a monitor 23. When an examiner performs a diagnosis with respect to a subject in a remote location via the communication line, an ultrasonic image can be displayed with sufficiently suppressed degradation of an image quality compared with an image quality of an original image, even at a low data rate of the communication line.

摘要： There is provided an excellent biological signal monitor device that allows a living tissue moving in accordance with a body motion or a vibration to be observed as if it were standing still. A reverse correction processing unit (114) subjects a B-mode image to reverse correction based on a movement amount of the living tissue detected by a movement amount detection unit (113), and outputs the B-mode image corresponding to the living tissue moving in accordance with a body motion as quasi-still image information. An arithmetic processing unit (115) subjects the quasi-still image information from the reverse correction processing unit (114) to arithmetic processing such as averaging and filter processing, so as to remove a random noise component. As a result, it is possible to display, for example, a contour portion of a blood vessel wall as the living tissue clearly.

摘要： An ultrasonic Doppler blood flowmeter has a Doppler scanning mode of operation to obtain information about blood speed and a B mode of operation to obtain information for a tomogram. In order to produce supplementary Doppler shift data for use during a B-mode scanning period, Doppler shift data from a phase detector is treated as complex data, and the difference in argument between two consecutive, complex Doppler shift data is detected. The supplementary Doppler shift data can then be calculated by an arithmetic circuit on the basis of the difference in argument between the consecutive complex Doppler shift data.
