Abstract: A systems and methods for tissue characterization using ultrasound are disclosed. One embodiment is for a system with a novel YB-scan transducer. The YB transducer is comprised of a plurality of separate and independent piezo-elements. The system is configured to scan a tissue or organ using two different frequencies to produce 2D images and two-frequency attenuation data to characterize tissue types. Other embodiments are presented permitting conventional B-scan imaging combined with A-mode scanning for two-frequency tissue characterization.

Abstract: An apparatus for improving the quality of the existing ultrasound diagnostic examination by non-invasively determining a type of tissue matter within a living entity consisting of application of two different ultrasound diagnostic methods simultaneously, in a sequence or alternate through the same transducer is disclosed. The apparatus uses a B-scan tissue image visualization as a guiding image to apply a tissue characterization method to determine an attenuation data for tissue matter and includes the steps of applying arbitrary waveform generator to produce a B-scan image of the tissue matter to be analyzed, selecting a region of interest on said image, detecting reflected signals from said region of interest, analyzing the reflected signals to determine attenuation data for the tissue matter.

Abstract: An apparatus for non-invasively determining a type of tissue matter and its state within a living entity consisting of application of two different diagnostic images simultaniously through the same B-scan transducer is disclosed. The apparatus uses a B-scan image visualization as a guiding image information for two-frequency attenuation method to determine an attenuation data for any chosen spot of interest and includes the steps of applying arbitrary waveform generator to produce a B-scan image of the tissue matter to be analyzed, selecting a region of interest on the image, positioning the indicator of the direction of the receiving reflected signals to the spot of interest, detecting reflected signals from said spot of interest, analyzing the reflected signals to determine attenuation data for the tissue matter.

Abstract: A method and apparatus for non-invasively determining a type of tissue and its state within a living entity are disclosed. The method includes the steps of using an imaging technique to generate an image of the tissue matter to be analyzed, selecting a region of interest on the image; positioning a device for transmitting ultrasonic signals at desired frequencies in a desired location relative to the tissue matter; transmitting ultrasonic signals at at least two different frequencies through the region of interest; detecting echo signals reflected by the tissue matter; and analyzing the echo signals to determine attenuation data for the tissue matter. The apparatus includes an imaging device for generating an image of the tissue matter to be analyzed, a device for selecting the region of interest, a device for transmitting ultrasonic signals, a receiver for detecting the echo signals, a display device for displaying the echo signals, and a computer for analyzing and calculating the attenuation data.
