Ultrasound imaging offers a safe, non-invasive, non-ionizing tool for clinical diagnosis. Ultrasound tomography would allow ultrasound imaging to reach its full potential, compared to X-ray, MRI, etc. It is based on inverse scattering and has the capability to resolve structures which are smaller than the wavelength of the incident wave, as opposed to conventional ultrasound imaging using echo method...
Sweep imaging Fourier transform (SWIFT) is an efficient (fast and quiet) specialized magnetic resonance imaging (MRI) method for imaging tissues or organs that give only short-lived signals due to fast spin-spin relaxation rates. Based on the idea of compressed sensing, this paper proposes a novel method for further enhancing SWIFT using chaotic compressed sensing (CCS-SWIFT). With reduced number...
Ultrasonic tomography technique has a great potential value in many applications such as medicine, underwater acoustics, non-destructive testing, etc. However, one of the most disadvantages of this technique is time consumption in reconstruction process. The distorted Born iterative method (DBIM) has been utilized to reconstruct the ultrasound tomography. It can take several iterations depend on the...
