The invention relates to an industrial testing device communicating with a data center located in a remote computer network, such as the cloud. Disclosed is a method of registering the device to the cloud and specifying the geographical location of the data center. The method includes selecting a data center from a list of available data centers based on regulations specific to a device type of the industrial testing device. Features are configured for communication between the device and the selected data center.

A tissue positioning system for contouring a patient tissue volume includes an axially displaceable interface having a surface configured to engage a breast or other tissue volume. A low pressure source applies a partial low pressure to the surface of the displaceable interface to secure the tissue volume to the surface, and the axially displaceable interface is biased to pull and contour the tissue volume when the tissue volume is secured to the surface. The axially displaceable interface is typically mounted on a telescoping support and the biasing is provided by the same low pressure used to secure the tissue volume.

A method and ultrasound imaging system includes transmitting first ultrasound energy with a first transmit pattern, receiving first ultrasound data based on the first ultrasound energy, and generating a first image based on the first ultrasound data. The method and system includes entering a shadow reduction mode and performing the following steps in the shadow reduction mode: transmitting second ultrasound energy with a second transmit pattern configured to have greater penetration than the first transmit pattern, receiving second ultrasound data based on the second ultrasound energy, generating a mask identifying a shadow region and generating an enhanced image including an enhanced shadow region, wherein the second ultrasound data is used to generate the enhanced shadow region, and displaying the enhanced image.

Various methods and systems are provided for dynamically adjusting user guidance based on a user's proficiency by tracking the same. In one example, a proficiency score for a user may be tracked over time and practice based on a pre-defined rubric for a given anatomical region and a given anatomical target within the anatomical region. During medical imaging, based on the proficiency score of the user, an amount of user guidance that is provided to the user may be adjusted. For example, user guidance may be automatically activated to guide the user during the imaging procedure when the proficiency score of the user is less than a threshold score.

Disclosed herein are dynamically adjusting ultrasound-imaging systems and methods thereof. For example, an ultrasound-imaging system can include an ultrasound probe, a console, and a display screen. The ultrasound probe includes an array of ultrasonic transducers that, when activated, emit generated ultrasound signals into a patient, receive reflected ultrasound signals from the patient, and convert the reflected ultrasound signals into corresponding electrical signals for processing into ultrasound images. The console is configured to execute instructions for dynamically adjusting a distance of activated ultrasonic transducers from a predefined target or area, an orientation of the activated ultrasonic transducers to the predefined target or area, or both the distance and the orientation of the activated ultrasonic transducers with respect to the predefined target or area. The display screen is configured to display a graphical user interface including the ultrasound images processed by the console from the corresponding electrical signals of the ultrasound signals.
