摘要： A flexure display is a display graph in which positions of a plurality of surface points and amounts of displacement are correlated. A slider provides a user interface for setting time. A time which is set through the slider is reflected on the flexure display or the like. The flexure display provides a graph showing an amount of displacement of each surface point at the time which is set through the slider. A load display shows a temporal change of an amount of load applied to the bone. A strain display shows a temporal change of an amount of strain of the bone. Time markers showing a predetermined time are displayed on the load display and strain display. The time markers are displayed according to the time which is set through the slider.

摘要： An ultrasonic diagnostic device for measuring the velocity of blood flow within a living body comprises a receiver for amplifying a received wave in accordance with a logarithmic amplification characteristic and at least one inverse logarithmic converter which produces an output having an inverse logarithmic characteristic with respect to the input thereto. As a result, the device can carry out high-precision measurement of blood flow even when the component of the received wave corresponding to the blood flow is much smaller than a component of the received wave corresponding to the wall of the blood vessel or heart through which the blood is flowing.

摘要： To accurately measure wave intensity as an evaluation value using an ultrasonic diagnostic apparatus, a measurement line is set in a tomogram and anterior and posterior walls of a blood vessel are tracked on the measurement line, so that a change waveform concerning a blood vessel diameter is prepared. A tracking gate S is set on the measurement line, so that a blood velocity change waveform is prepared based on echo data concerning a part within the tracking gate S, the change waveform indicating averaged blood velocity. Wave intensity is calculated based on the blood vessel diameter change waveform and the blood velocity change waveform. Prior to the calculation of wave intensity, the blood vessel diameter change waveform is calibrated based on the maximum and minimum blood pressure values into a blood pressure waveform. A beam for Doppler measurement may be set intersecting with the displacement measurement beam.
