Abstract
Certain aspects pertain to systems, apparatus, and methods for one or both of thermoacoustic and ultrasound tomography.
Claims25
An imaging system, comprising:
- one or more dielectric-loaded radio frequency antenna apparatus, each dielectric-loaded radio frequency antenna apparatus comprising a radio frequency antenna for transmitting radio frequency pulses and an internal volume at least partially filled with a dielectric material;
- and
- an ultrasonic sensor array configured to detect acoustic waves.
An ultrasonic sensor array apparatus, comprising:
- a plurality of ultrasonic transducers;
- a plurality of integrated pre-amplifiers in one-to-one correspondence with the ultrasonic transducers;
- and
- an ultrasonic transmitter configured to transmit ultrasound pulses.
1 more element
A dielectric-loaded radio frequency antenna apparatus, comprising:
- an internal volume at least partially filled with a dielectric material;
- and
- a radio frequency antenna;
- a gas-filled spacer between the internal volume and a region external to the dielectric-loaded radio frequency antenna.
1 more element
A thermoacoustic and ultrasound tomography imaging method:
- delayed triggering of radio frequency and ultrasonic pulses to interleave thermoacoustic signals with ultrasonic signals detected by an ultrasonic sensor array;
- reconstructing thermoacoustic image data and ultrasonic image data;
- and
- co-registering the thermoacoustic image data and ultrasonic image data.
