Abstract: An object sizing system sizes an object positioned within a patient. The object sizing system identifies a presence of the object. The object sizing system navigates an elongate body of an instrument to a position proximal to the object within the patient. An imaging sensor coupled to the elongate body captures one or more sequential images of the object. The instrument may be further moved around within the patient to capture additional images at different positions/orientations relative to the object. The object sizing system also acquires robot data and/or EM data associated with the positions and orientations of the elongate body. The object sizing system analyzes the captured images based on the acquired robot data to estimate a size of the object.

The processing circuitry is configured to output the projection image.

Abstract: A C-arm, or a mobile intensifier device, is one example of a medical imaging device that is based on X-ray technology. Because a C-arm device can display high-resolution X-ray images in real time, a physician can monitor progress at any time during an operation, and thus can take appropriate actions based on the displayed images. Monitoring the images, however, is often challenging during certain procedures, for instance during procedures in which attention must be paid to the patient's anatomy as well as a medical imaging device display. In an example, a surgical instrument assembly includes a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument.

Abstract: Method for scanning for second object on or within first object starts by receiving information on first object and second object. Task lists are generated that include at least one task action based on information on first object and second object. Based on task lists, beamer is then signaled to generate and send first signal to first probe unit to perform first beam firing.

Upon determination that first object is identified, based on task list, beamer is signaled to generate and send second signal to second probe unit to perform second beam firing. Receiver processes second data signal from second probe unit that is then analyzed to determine if second object is identified using processed second data signal. Other embodiments are described.

Abstract: The present embodiments relate generally to systems, methods, and apparatus for determining a heart rate of an imaged heart in an ultrasound image feed. A plurality of ultrasound images can first be acquired. For each ultrasound image of the plurality of ultrasound images, the image can be divided into a plurality of regions; where each region is positioned so that the region corresponds to a substantially similar region location present across the plurality of ultrasound images. For each region location on each of the plurality of ultrasound images, a statistical calculation on image data of the region location can be performed. For each region location, a frequency of change in the statistical calculation over the plurality of ultrasound images can then be determined. The region location having a dominant determined frequency of change in the statistical calculation (over the plurality of ultrasound images) can be identified as a region of interest (ROI).
