High frequency synthetic ultrasound array incorporating an actuator |
摘要 |
The present invention discloses a method and apparatus for ultrasound imaging with improved spatial sampling. The device includes a plurality of ultrasound imaging elements each having a pitch defined by the center to center spacing of the ultrasound imaging elements; and a motion mechanism operatively connected to the plurality of ultrasound imaging elements and adapted to move the plurality of ultrasound imaging elements over a distance to increase the spatial sampling of the plurality of ultrasound imaging elements. The method of the present invention includes transducing a signal from one or multiple ultrasound imaging elements within an array of ultrasound imaging elements; moving the array of ultrasound imaging elements a distance less than the pitch; and transducing at least one additional signal from the ultrasound imaging element.
