Abstract: The present disclosure relates to extraction of probe motion estimates from acquired ultrasound image frames. Such image-extracted probe motion data can be used alone or in combination with sensed motion data, such as acquired using an inertial measurement unit (IMU). In certain implementations, the image-extracted probe motion can be used to provide or maintain anatomic context in a sequence of images or to provide guidance to a user.

Abstract: A cleaning system and method use an ultrasound probe, a coupling mechanism, and a controller to clean equipment of a vehicle system. The ultrasound probe enters into an engine. The ultrasound probe emits ultrasound pulses and the coupling mechanism provides an ultrasound coupling medium between the ultrasound probe and one or more components of the engine. The controller drives the ultrasound probe to deliver the ultrasound pulse through the coupling medium to a surface of the one or more components of the engine. The ultrasound probe delivers the ultrasound pulse to remove deposits from the one or more components of the engine.

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: The present approach generally relates to systems and methods for implementing energy modulated tomographic imaging of nanoparticles. In certain embodiments, a first energy is used to activate probe particles labeling an anatomy or tissue of interest. The probe particles, once activated, emit photons at a different rate and/or spectrum in response to an underlying physiological event, such as action potentials propagating in the labeled anatomy or tissue. The emitted photons may then be detected and used to map or image the occurrence of the physiological event.

Abstract: A cleaning system and method use an ultrasound probe, a coupling mechanism, and a controller to clean equipment of a vehicle system. The ultrasound probe enters into an engine. The ultrasound probe emits ultrasound pulses and the coupling mechanism provides an ultrasound coupling medium between the ultrasound probe and one or more components of the engine. The controller drives the ultrasound probe to deliver the ultrasound pulse through the coupling medium to a surface of the one or more components of the engine. The ultrasound probe delivers the ultrasound pulse to remove deposits from the one or more components of the engine.

Abstract: Systems and methods for navigation are presented. First and second response signals received from at least one magnetic sensor operatively coupled to a target device in response to a magnetic field are measured at reference and reversed sensitivity while an alignment of magnetic domains corresponding to the magnetic sensor remains unchanged. A useful portion of the first response signal is determined by eliminating common-mode noise from the first response signal based on a difference between the first and second response signals. Alternatively, a bias signal having a desired bias frequency is applied to shift a signal frequency of a response signal of a magnetoresistance sensor that includes common-mode noise. A useful portion of the response signal is determined by measuring the response signal at a shifted frequency that is a sum of the signal and bias frequencies. A position of the subject is then determined based on the useful portion.
