Abstract: An ultrasound imaging system, a method for ultrasound imaging and a non-transitory computer readable medium that stores instructions executable by one or more processors to perform the method for ultrasound imaging are presented. The method includes convolving one or more base ultrasound pulses corresponding to a particular frequency with a desired code to generate an extended excitation wave. Further, the extended excitation wave is transmitted to a broadband ultrasound transducer to be transmitted towards the target. Subsequently, echo signals reflected back from the target in response to the extended excitation wave are received and de-convolved. One or more ultrasound images of the target corresponding to multiple frequencies are generated based on the de-convolved echo signals.

Abstract: Improvement of the dynamic range of a radiation detector is described. In one embodiment, one or more non-destructive readout operations are performed during a radiation exposure event to acquire data used to improve the dynamic range of the detector. In one implementation, one or more non-destructive readouts of pixels are performed prior to saturation of the pixels during an X-ray exposure so as to obtain non-saturated measurements at the pixels. In an additional implementation, non-destructive readouts of pixels are performed between exposure events so as to obtain an estimate of electronic noise during a multi-exposure examination.

Abstract: A method for X-ray imaging includes determining one or more pre-shot parameters corresponding to a region of interest in a subject based on an optical image of the region of interest obtained from an optical sensor. The method further includes controlling an X-ray device to generate a pre-shot X-ray image using a first X-ray dosage, based on the one or more-pre-shot parameters. The method also includes determining at least one main-shot parameter based on the pre-shot X-ray image. The method includes controlling the X-ray device to generate a main-shot X-ray image using a second X-ray dosage greater than the first X-ray dosage, based on the at least one main-shot parameter.

Abstract: A silicon photomultiplier (SiPM) based detection system includes a plurality of scintillators, SiPMs, a front end circuit, adjustment circuits, and an energy and position processing unit. The SiPMs have a non-linear response to energy deposition corresponding to radiation detection. The adjustment circuit is configured to receive an analog signal from SiPMs, and to provide an adjusted analog signal, which is configured to simulate a signal corresponding to a linear response. The energy and position processing unit utilizes the adjusted signal to provide energy and position information of detected events in the detector block.

Abstract: Embodiments for aggregating multiple data sources on a single display device are provided. In one example, a computing device comprises at least one input configured to receive data from one or more data sources, a user interface to receive user input, and instructions to identify an event of a procedure based on one or more of data received from the one or more data sources and user input received via the user interface, and arrange one or more display information elements on a display device based on the identified event and a workflow protocol.

Abstract: The present approach relates to the use of a spatially registered detector docking compartment to determine source and detector alignment in a patient imaging context. In certain implementations, sensors and/or cameras provide visual data that may be analyzed to determine a spatial relation between an X-ray source and landmarks provided on a patient support surface, where the landmarks have a known spatial relationship to a detector positioned beneath the patient support surface.
