Untrasound diagnostic equipment for calculating and displaying integrated backscatter or scattering coefficients by using scattering power or scattering power spectrum of blood

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.
