Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Background:

Pulse compression in ultrasound imaging enhances penetration depth and axial resolution using long coded pulses and matched filtering.
Tissue attenuation and computational load have limited real-time implementation of these methods.
Existing methods often suffer from receiver filter mismatch due to frequency-dependent tissue attenuation.

Purpose of the Study:

To develop a real-time, low-computational-cost coded-imaging system for ultrasound.
To investigate the effects of tissue attenuation on pulse compression performance.
To improve signal-to-noise ratio (SNR) and penetration depth in ultrasound imaging.

Main Methods:

Implemented a real-time coded-imaging system on the ULA-OP research platform, extending firmware and software.
Utilized a single digital signal processor for pulse compression on beamformed and demodulated data.
Tested linear frequency modulated (FM) chirps and developed an attenuation compensation scheme by shifting demodulation frequency.

Main Results:

Achieved image line production in under 20 μs, enabling high frame rates (e.g., 200 fps for 192-line frames).
Demonstrated significant SNR gains (e.g., 13 dB with a chirp signal having Time-Bandwidth product (BT) of 19) in attenuating media.
Reported a 2.7 dB SNR increase using a novel attenuation compensation scheme, further enhancing penetration depth in phantom and in vivo tests.

Conclusions:

The developed system offers a practical, low-computational-cost solution for real-time ultrasound coded-imaging.
The study provides insights into optimizing receive compression filters for tissue attenuation.
The novel attenuation compensation scheme is simple, effective, and easily implementable, enhancing ultrasound imaging performance.
