METHOD AND SYSTEM FOR OBLIQUE BACKSCATTERING ULTRASOUND IMAGING
First Claim
Patent Images
1. An oblique backscatter acoustic imaging system comprising:
- a transmitting transducer configured to produce focused acoustic waves propagating into a target;
two or more receiving transducers positioned on opposite sides of the transmitting transducer and configured to detect diffuse backscatter of the acoustic waves passing through the target; and
a signal processor configured to receive a signal from at least one of the receiving transducers representative of the detected backscatter of the acoustic waves.

Abstract
An Oblique Backscatter Ultrasound imaging system includes a transceiver that has an US source and a plurality of US detectors configured in receive signals off axis from the US source. While the system is arranged in a reflective configuration, the device produces transmissive contrast signals to yield improved images. The transceiver can be mounted to a movable stage or robotic arm to enable it to scan the surface of a target. Alternatively, scanning can be performed by 1D or 2D phased-array transmission or detection.

11. An oblique backscatter acoustic imaging system comprising:
-
two or more transmitting transducers, each configured to produce acoustic waves propagating into a target; a receiving transducer positioned between the transmitting transducers and adapted to detect diffuse backscatter of the acoustic waves passing through the target; and a detector signal processor adapted to receive a signal from the receiving transducer representative of the detected backscatter of the acoustic waves. - View Dependent Claims (12, 13, 14)
