Translational Computed Tomography: A New Data Acquisition Scheme
نویسندگان
چکیده
Today, most computed tomography (CT) systems acquire projection data from several hundred to thousands of directions by employing multi-row (2-D) or flat-panel detectors (cone-beam for 3-D imaging). It is important to notice the following fact: modern CT systems all rely on a rotational movement. The most widely utilized reconstruction algorithms, as for instance the well-known Feldkamp method, are based on filtered back projection (FBP). These algorithms afford a series of projection images covering an angular range of at least 180°.

A new scheme for view-dependent data differentiation in fan-beam and cone-beam computed tomography.
In computed tomography, analytical fan-beam (FB) and cone-beam (CB) image reconstruction often involves a view-dependent data differentiation. The implementation of this differentiation step is critical in terms of resolution and image quality. In this work, we present a new differentiation scheme that is robust to changes in the data acquisition geometry and to coarse view sampling. Our scheme...
متن کاملFPGA based data acquistion and digital pulse processing for PET and SPECT
The most important aspects of nuclear medicine imaging systems such as Positron Emission Tomography (PET) or Single Photon Emission Computed Tomography (SPECT) are the spatial resolution and the sensitivity (detector efficiency in combination with the geometric efficiency). Considerable efforts have been spent during the last two decades in improving the resolution and efficiency by developing ...

متن کاملTop-level design and pilot analysis of low-end CT scanners based on linear scanning for developing countries.
The goal is to develop new architectures for computed tomography (CT) which are at an ultra-low-cost for developing countries, especially in rural areas. The proposed general scheme is inspired by the recently developed compressive sensing and interior tomography techniques, where the data acquisition system targets a region of interest (ROI) to acquire limited and truncated data. Similar to li...
متن کاملDictionary-Learning-Based Reconstruction Method for Electron Tomography
Electron tomography usually suffers from so-called “missing wedge” artifacts caused by limited tilt angle range. An equally sloped tomography (EST) acquisition scheme (which should be called the linogram sampling scheme) was recently applied to achieve 2.4-angstrom resolution. On the other hand, a compressive sensing inspired reconstruction algorithm, known as adaptive dictionary based statisti...
