摘要： An ultrasonic transducer element can configured to generate ultrasonic energy directed into tissue of a subject and configured to receive a portion of the ultrasonic energy reflected by a target located within the tissue. The ultrasonic transducer can include a surface configured to provide or receive the ultrasonic energy, the surface including an area of greater than or equal to about 4λ2, or the ultrasonic transducer element can be included in an array having a spacing between at least two adjacent ultrasound elements of less than or equal to about ½λ, and the array comprising an aperture that is at least approximately symmetrical in two axes. A three-dimensional representation of one or more of a location, shape, or orientation of at least a portion of the target can be presented via the display.

摘要： Methods, systems, and computer readable media for monitored application of mechanical force to samples using acoustic energy and mechanical parameter value extraction using mechanical response models can be used for determining mechanical property parameters of a sample. An exemplary method includes applying acoustic energy to a sample to apply a mechanical force to the sample, measuring a response by the sample during the application of the acoustic energy, measuring a recovery response of the sample following cessation of the application of the acoustic energy, and determining a value for at least one additional mechanical property parameter of the sample based on the response measured during application of the acoustic energy and the recovery response measured following cessation of the application of acoustic energy.

摘要： A hand-held apparatus can be used to assist in guiding a probe or locating a particular anatomical target in a subject. The apparatus can include an ultrasonic transducer located on or within a housing and configured to generate ultrasonic energy directed into tissue of a subject and configured to receive a portion of the ultrasonic energy reflected by a target located within the tissue. In an example, the apparatus can include a motion tracking circuit configured to provide information indicative of a motion of the hand-held apparatus to the processor circuit, and a display configured to present information about a location of the target with respect to a portion of the hand-held apparatus, the information about the location determined by the processor circuit using the obtained information indicative of the ultrasonic energy reflected by the target and the information indicative of the motion of the hand-held apparatus.
