Ultrasound devices methods and systems

摘要

Ultrasound methods, devices, and systems are described which support a useful compromise in terms of spatial resolution and temporal resolution for capturing motion in tissue structures. Tissue engineering articles, methods, systems, and devices which employ ultrasound to deliver biological agents to selected regions of a tissue scaffold, deliver mechanical stimulation to cells growing in a tissue scaffold, and enhance the perfusion of fluids through tissue scaffolds.

1. A method for estimating properties of motion of a body structure using ultrasound, comprising:
using a controller of an ultrasound machine;
receiving a first input signal from a user interface representing data indicating a sampling rate and storing sampling rate data responsive thereto;receiving a second input signal from a user interface data indicating a motion estimation frequency and storing motion estimation frequency data responsive thereto;responsively to the sampling rate and motion estimation frequency data; scanning the body structure using ultrasound to generate a series of image frames at the sampling rate, each image representing the configuration of the body structure at a point in time and spanning a field of view of an ultrasound scanner;the scanning the body structure including capturing displacements of portions of the body structure within a fraction of the field of view at the motion estimation frequency;estimating a time-dependent configuration of the body structure within the entirety of the field of view and combining with the motion estimation to outputting an image sequence showing representations of the image frames as a video sequence with the motion data responsive to the displacements superposed thereon.
