    Abstract: A method and system optimize a thermoacoustic transducer functionality that is utilized in a thermoacoustic imaging system. The method and system select a pre-determined transducer geometry for the thermoacoustic imaging system, utilize the thermoacoustic imaging system with the pre-determined transducer geometry to generate at least one impulse in a field of view, acquire data from the impulse, reconstructing the data to generate N-dimensional impulse responses based upon respective channel responses, respective view responses, and a function of the acquired data, utilize the N-dimensional transforms for each image to generate a value for the pre-determined transducer functionality, and utilize the value for the pre-determined transducer functionality to determine an optimum thermoacoustic transducer functionality.

    Abstract: A system (10) is for performing ECG measurements and comprises a probe (12) with an integrated one or more ECG electrodes (22) and an ultrasound sensing means (18), such as a transducer arrangement. The probe thus provides a mobile ECG electrode which can be sequentially moved between a set of different locations on the body for acquiring ECG measurements from different angles relative to the heart (i.e. different 'leads'). Positioning of the probe in each required location is guided by a position guidance function which uses ultrasound data acquired by the ultrasound sensing means to locate the probe (with reference to an ultrasound body atlas (28) or map), and uses a stored set of reference body locations to guide a user with guidance information as to how to move the probe to arrive at a next target electrode location. In examples, the user may be guided through a sequence of electrode locations, with ECG data acquired at each one, thereby sequentially building up a set of standard ECG lead measurements.

    Abstract: Systems and methods for improved visualization of non-de struct ve testing (NDT) measurements are provided. A probe can be employed to acquire NDT measurements of a target. Images of the target can also be captured during testing. The captured images can be analyzed to identify selected objects therein (e.g., the target, the probe, etc.) Graphical user interfaces (GUIs) including the NDT measurements can be further generated for viewing in combination with the target. In one aspect, the GUI can be viewed as a hologram within a display of an augmented reality device when viewing the target. In another aspect, the GUI can be projected upon the target. The GUI can be configured to overlay the NDT measurements at the location where the NDT measurements are acquired. This display of the NDT measurements can help an inspector more easily relate the NDT measurements to the target and improve reporting of the NDT measurements.
