A novel dual energy CT-based attenuation correction method in PET/CT systems: A phantom study
In present PET/CT scanners, PET attenuation correction is performed by relying on the information given by CT scan. In the CT-based attenuation correction methods, dual-energy technique (DECT) is the most accurate approach, which has been limited due to the increasing patient dose. In this feasibility study, we have introduced a new method that can implement dual-en...

متن کاملA New Computer-Aided Detection System for Pulmonary Nodule in CT Scan Images of Cancerous Patients
Introduction: In the lung cancers, a computer-aided detection system that is capable of detecting very small glands in high volume of CT images is very useful.This study provided a novelsystem for detection of pulmonary nodules in CT image. Methods: In a case-control study, CT scans of the chest of 20 patients referred to Yazd Social Security Hospital were examined. In the two-dimensional and ...
متن کاملDual-Energy CT in Neuroimaging
Image contrast in CT is mostly dependent on elements with high atomic weight, such as calcium, iron, and iodine The concentrations of these elements can be calculated from dual-energy x-ray data based on their characteristic attenuation patterns Dual-energy CT may can be helpful in neuroimaging to: Differentiate between hemorrhage and iodinated contrast agents in brain parenchyma Improve CT ang...
متن کاملNonuniqueness in dual-energy CT.
PURPOSE The goal is to determine whether dual-energy computed tomography (CT) leads to a unique reconstruction using two basis materials. METHODS The beam-hardening equation is simplified to the single-voxel case. The simplified equation is rewritten to show that the solution can be considered to be linear operations in a vector space followed by a measurement model which is the sum of the ex...
