Image Reconstruction in Ultrasound Reflection Tomography using Quick High-Resolution Method

High resolution image reconstruction in ultrasound computer tomography using deconvolution

Ultrasound computer tomography is an imaging method capable of producing volume images with high spatial resolution. The imaged object is enclosed by a cylindrical array of transducers. While one transducer emits a spherical wavefront (pulse), all other transducers are recording the radiofrequency (RF) a–scans simultaneously. Then another transducer acts as the emitter and so on. In this paper ...

Reconstruction of High-Resolution Computed Tomography Image in Sinogram Space

An important part of any computed tomography (CT) system is the reconstruction method, which transforms the measured data into images. Reconstruction methods for CT can be either analytical or iterative. The analytical methods can be exact, by exact projector inversion, or non-exact based on Back projection (BP). The BP methods are attractive because of thier simplicity and low computational co...

Ultrasound Tomography in Circular Measurement Configuration using Nonlinear Reconstruction Method

Abstract— Ultrasound tomography offers the potential for detecting of very small tumors whose sizes are smaller than the wavelength of the incident pressure wave without ionizing radiation. Based on inverse scattering technique, this imaging modality uses some material properties such as sound contrast and attenuation in order to detect small objects. One of the most commonly used methods in ul...
