VOLUMETRIC IMAGING AND RELATED APPARATUS AND METHODS
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.

317 . A method, comprising:
accessing at least one volumetric image of a subject calculated using a plurality of measurements of the subject, the plurality of measurements resulting at least in part from the detection of radiation by an imaging device;
identifying a point of view within the subject, wherein identifying the point of view comprises identifying a location within the subject; and
displaying the at least one volumetric image to a viewer from the identified point of view.
318 . The method of claim 317 , wherein the imaging device is an ultrasound imaging device.
319 . The method of claim 318 , wherein the plurality of measurements resulted at least in part from the detection of ultrasound radiation by the ultrasound imaging device operating in a transmissive modality.
320 . The method of claim 317 , wherein said displaying comprises displaying three-dimensionally, via a three-dimensional display, the at least one volumetric image to the viewer from the identified point of view.
321 . The method of claim 317 , wherein said identifying comprises identifying a plurality of points of view within the subject, including the point of view, and wherein said displaying comprises displaying the at least one volumetric image to the viewer from at least two of the identified points of view.
322 . The method of claim 321 , wherein locations corresponding to the plurality of points of view lie along a path through the subject, and wherein said displaying comprises displaying the at least one volumetric image to the viewer in a sequence corresponding to an ordering of the locations along the path.
323 . The method of claim 322 , wherein said displaying comprises displaying, via a three-dimensional display, the at least one volumetric image from the at least two of the identified points of view.
324 . The method of claim 317 , wherein said identifying further comprises identifying an angle within the subject.
325 . The method of claim 317 , wherein said identifying comprises identifying the point of view based at least in part on input received from the viewer, wherein the input specifies the point of view.
326 . The method of claim 317 , wherein said identifying comprises automatically identifying the point of view at least in part by applying an image analysis technique to the at least one volumetric image.
