Abstract: Systems and methods for receiving touch-based input from an operator of an imaging device are disclosed herein. In one embodiment, an ultrasound imaging device is configured to receive tactile input from an operator. The imaging device presents an ultrasound image to the operator and the operator can perform one or more touch inputs on the image. Based on the received input, the imaging device can update the display of the image.

Abstract: Adjustment of operation of an ultrasound imaging system may be based at least in part on one or more characteristics represented in ultrasound return signals from two or more sample volumes. Adjustment may include adjusting a principal sample volume location or selecting a new principal sample volume. For example, a location of a principal sample volume may be adjusted or new principal sample volume selected so as to remain focused on an identified region of interest or to maintain the principal sample volume relative to some structure or reference. The principal sample volume may be maintained in the center or along a centerline of an artery or other structure, as the transducer array is moved along the artery or structure.
