3D-Image Reconstruction in Highly Collimated 3D Tomography
نویسندگان
چکیده
The paper introduces a novel method for image reconstruction in 3D tomography, called Searchlight Computed Tomography, which reduces the overall radiation exposure when primarily the reconstruction of a specified region of interest is required. To achieve this goal, the Searchlight CT approach restricts the acquisition essentially to X-rays passing through the region of interest of a 3D object, yet the algorithm provides a stable and robust reconstruction of the region of interest. The Searchlight CT algorithm is based on an iterative procedure for which generic conditions for the convergence are provided. Its performance is validated on experimental data.

Full 3d Roi Image Reconstruction from Highly Collimated Computed Tomography
We introduce a novel method for full 3D Region Of Interest (ROI) reconstruction in computed tomography (CT), called Searchlight CT, which reduces the overall radiation exposure when primarily the reconstruction of a specified ROI is required. To achieve this goal, the Searchlight CT approach restricts the acquisition essentially to X-rays passing through the ROI, yet the algorithm provides a st...
متن کاملUltra-Fast Image Reconstruction of Tomosynthesis Mammography Using GPU
Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...
متن کاملFast System Matrix Calculation in CT Iterative Reconstruction
Introduction: Iterative reconstruction techniques provide better image quality and have the potential for reconstructions with lower imaging dose than classical methods in computed tomography (CT). However, the computational speed is major concern for these iterative techniques. The system matrix calculation during the forward- and back projection is one of the most time- cons...

Introduction: Radiation imaging is one of the applicable methods in diagnostic medicine and nondestructive testing for industrial applications. In nondestructive 3D imaging, in addition to the radiation source, there is a requirement for a suitable detection system, data acquisition system, mechanical sections for moving objects, reconstruction algorithm and finally a computer for processing an...
متن کامل3-D computed tomography reconstruction: another tool to teach anatomy in the veterinary colleges
This letter underpins the use of three-dimensional computed tomography (3D-CT) reconstruction as an aid to teach veterinary anatomy. Cases were presented to students in order to observe normal and clinically abnormal patients. The images provided excellent details of relevant structures and could serve as a tool for teaching anatomy. Many sources describe different options to enhance anatomical...
