摘要： Ultrasound diagnostic equipment comprises a tissue power unit for calculating tissue scattering power of tissues of an object of measurement in an organ, a blood power unit for calculating scattering power of blood in the organ and estimating blood scattering power at a portion of the tissues of the object of measurement by using the calculated scattering power of the blood, an integrated backscatter unit for normalizing the tissue scattering power by using the estimated blood scattering power and calculating an integrated backscatter by the normalized tissue scattering power, and a display unit for displaying the integrated backscatter. Therefore, the integrated backscatter of the tissues can be quantitatively estimated without being influenced by attenuation. Furthermore, this estimated quantitative integrated backscatter of the tissues is displayed on the display unit accompanied with a B-mode image, an electrocardiogram, and the like, so that diagnostic accuracy can be increased.

摘要： The present invention relates to a signal processing apparatus for quantitatively measuring ultrasonic characteristics of a medium, such as a human body and realizes the high speed quantitative measurement by processing all signals in the time domain. In the processing for eliminating an error, produced by a degree of convergence of the ultrasonic beam, a correcting function that is a function of the depth and frequency is employed. The correcting function is measured in a no-attenuation medium and converted into a form suited to the time domain processing. The function is stored and such frequency characteristics of the function are sequentially read during an actual medium measurement to control the characteristic of a variable characteristic filter to correct the received signal.

摘要： A diagnosis apparatus for discriminating a property of the tissue to be observed from the reflected ultrasonic wave uses the nature of the fine structure of the tissue, and more practically uses the interval of small reflecting bodies dispersely distributed in the tissue as the parameters. The intervals flucatuate. Therefore, an average value and/or a degree of fluctuation is calculated and is displayed. For obtaining the average interval, a method of using the cepstrum of the received signal or a method of using the self-correlation of the received signal can be used.

摘要： An ROI (region of interest) is drawn according to common and shape variables. The common variables are common to ROIs irrespectively of the shape thereof. Expressions defining relations between the common and shape variables are determined and stored for each ROI in advance. When an instruction is issued to replace a first ROI with a second ROI having a different shape, shape variables for the second ROI are calculated from the common variables of the first ROI according to the expressions, and the second ROI defined by the calculated shape variables is displayed.
