摘要: This application presents a system and related methods that analyze a volume of tissue using ultrasound waveform tomography imaging. By using frequency-domain waveform tomography techniques and a gradient descent algorithm, the system can reconstruct the sound speed distributions of a volume of tissue, such as breast tissue, of varying densities with different types of lesions. By allowing sound speed to have an imaginary component that characterizes sound attenuation, the system can classify the different types of lesions with a fine granularity.

摘要: A method of characterizing the pathological response of tissue to a treatment plan, including: obtaining a set of sequential morphology renderings of the tissue, wherein each rendering corresponds to a particular point in time during the treatment plan; generating a set of representative values of a biomechanical property of the tissue for the set of renderings, wherein each representative value is based on a corresponding rendering; determining a trend of the biomechanical property based on the set of representative values; and predicting response of the tissue to the treatment plan based on the trend of the biomechanical property.

摘要: A method for characterizing tissue of a patient, including receiving acoustic data derived from the interaction between the tissue and the acoustic waves irradiating the tissue; generating a morphology rendering of the tissue from the acoustic data, in which the rendering represents at least one biomechanical property of the tissue; determining a prognostic parameter for a region of interest in the rendering, in which the prognostic parameter incorporates the biomechanical property; and analyzing the prognostic parameter to characterize the region of interest. In some embodiment, the method further includes introducing a contrast agent into the tissue; generating a set of enhanced morphology renderings of the tissue after introducing the contrast agent; determining an enhanced prognostic parameter from the enhanced morphology renderings; and analyzing the enhanced prognostic parameter.
