Abstract
Apparatus and methods are described that include ultrasound imaging devices, which may operate in a transmissive ultrasound imaging modality, and which may be used to detect properties of interest of a subject such as index of refraction, density and/or speed of sound. Devices suitable for performing high intensity focused ultrasound (HIFU), as well as HIFU and ultrasound imaging, are also described.

344. A method, comprising:
-
accessing a plurality of measurements of a subject, the plurality of measurements resulting at least in part from the detection of ultrasound radiation by an ultrasound imaging device, the ultrasound imaging device comprising a plurality of ultrasound sources including a first ultrasound source and a plurality of ultrasound sensors including a first ultrasound sensor; calculating, using at least one processor, a first image of the subject from the plurality of measurements by using first path length information for a path between the first ultrasound source and the first ultrasound sensor; calculating, using the at least one processor, second path length information at least in part by computing refractive paths using the first image; and calculating, using the at least one processor, a second image of the subject from the plurality of measurements by using the second path length information. - View Dependent Claims (345, 346, 347, 348, 349, 350, 351, 352, 353)
