Abstract: The disclosure provides a method, a system, an apparatus, and a computer program product for determining IFP, IFV, and fluid flow inside tumors. In one example, a method for estimating tumor parameters is disclosed. This method includes: (1) receiving image data from a tumor, (2) obtaining strain data of the tumor from the image data, and (3) determining a tumor parameter, such as IFP and IFV, employing the strain data and an analytical model. Additional tumor parameters can be determined employing the strain data and other analytical models. The additional tumor parameters include compression-induced fluid pressure, velocity and flow inside the tumor, parameter? employing the fluid pressure, the ratio between vascular permeability and interstitial permeability, and the ratio of peak IFP and effective vascular pressure. Each of these parameters can be employed for analyzing, monitoring, treating, testing, etc., tumors or the effects of drugs on the tumors.

Abstract: The invention is directed toward a new method for estimating and imaging the spatial and temporal mechanical behavior of materials in responses to a mechanical stimulus. This method is designed to work in inherently noisy applications, such as the imaging of the time-dependent mechanical behavior of biological tissues in vivo and using a preferred hand-held configuration of scanning.

Abstract: The disclosure relates to a method of measuring tissue hydration or a bodily fluid such a lymph or interstitial fluid. In the method, at least one elastographic parameter of a tissue or bodily fluid may be measured to obtain an elastographic parameter measurement that correlates with a mechanical, pathological, physiological or functional property of the tissue or bodily fluid. The elastographic parameter measurement may be correlated with a tissue hydration value or bodily fluid value, including quantitative tissue hydration or bodily fluid values. Multiple measurements taken over time may be used to detect changes in tissue hydration, amounts of bodily fluid, bodily fluid movement, or rate of clearance of a bodily fluid. The disclosure also relates to a device containing a ultrasound transducer, circuitry able to perform methods of the disclosure, and a display able to display tissue hydration or bodily fluid information.
