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.
Claims14
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.
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.
