Technology for guiding a user to collect clinically usable ultrasound images is described. In some embodiments, an ultrasound device may automatically change the elevational steering angle of its ultrasound beam (e.g., using beamforming) in order to collect ultrasound data from different imaging planes within the subject. A processing device in operative communication with the ultrasound device may select one of the collected ultrasound images based on its quality (e.g., select the ultrasound image having the highest quality), and then continue to collect ultrasound images using the elevational steering angle at which the selected ultrasound image was collected.

A system is provided for augmenting a three-dimensional (3D) model of a heart to indicate the tissue state. The system accesses a 3D model of a heart, accesses two-dimensional (2D) images of tissue state slices of the heart, and accesses source location information of an arrhythmia. The system augments the 3D model with an indication of a source location based on the source location information. For each of a plurality of the tissue state slices of the heart, the system augments a 3D model slice of the 3D model that corresponds to that tissue state slice with an indication of the tissue state of the heart represented by the tissue state information of that tissue state slice. The system then displays a representation of the 3D model that indicates the source location of the arrhythmia and the tissue state of the heart.

Certain embodiments describe a system, method, and apparatus for ultrasound imaging. For example, the system can include a probe comprising a transducer configured to transmit or receive ultrasound waves. The system can also include a display communicatively coupled to the probe and one or more processors. The one or more processors cause the ultrasound system to detect, using the probe, one or more markings of a membrane located on a skin of a patient. The ultrasound system is also caused to determine position of the probe based on the one or more markings. In addition, the ultrasound system is caused to render on the display an indication of the position of the probe.

This method, for determining the local intensity (I.sub.0) of an acoustic field propagating in a target region of a soft solid, at a position located within said target region, includes at least the following steps: determining (102) a value of an ultrasound attenuation coefficient (α) of the soft body in the target region; determining (104) a value of the shear modulus (μ) of the soft body in the target region; determining (106) a value of the speed of sound (c) in the target region of the soft body; and building (110), with the values determined in steps a), b) and c), a viscoelastic model (M) of a steady-state displacement induced by an acoustic field having a time invariant shape or a viscoelastic model of a difference between two steady-state displacements induced by an acoustic field having a time invariant shape. Moreover, this method also includes the following steps: applying (112) to the target region the acoustic field emitted by an ultrasound source, for a duration such that the acoustic field induces a steady-state localized deformation (Formula (I)) of the soft body in the target region; measuring (114) at least one steady state displacement induced by the acoustic field at a given position in the target region; and computing (116) the amplitude of the intensity of the acoustic field at said given position by inverting the viscoelastic model (M) at said given position, for the displacement(s) measured at step f).
