Dual energy computed tomography for explosive detection
Single energy computed tomography (CT) scanners use measurements of densities to detect explosives in luggage. It is desirable to apply dual energy techniques to these CT scanners to obtain atomic number measurements to reduce false alarm rates. However, the direct application of existing dual energy techniques has practical problems, such as, approximation errors and lack of boundary constrain...
متن کاملAn Introduction to Dual Energy Computed Tomography
Introduction The idea of computed tomography (CT) was first introduced in the 1960’s with the development of modern computer technology. The first scanners were commercially available in the 1970’s, and grew in popularity through the 1980’s. The innovation of helical-scanning CT produced true volume imaging with sub-millimeter resolution. CT can be used for both anatomical as well as pathologic...
متن کاملClinical applications of virtual, non-contrast head images derived from dual-source, dual-energy cerebrovascular computed tomography angiography
Background: This study set out to evaluate the utility of cerebrovascular virtual non-contrast (VNC) scans. Materials and Methods: Conventional non-contrast (CNC) and dual-energy computed tomography angiography (DE-CTA) head scans were conducted on 100 subjects, of which 46 were normal, 15 had parenchymal hematomas of the brain, 13 had ischemic infarction, 22 had tumors, and 4 had calcified les...
متن کاملDetection of calcium pyrophosphate dihydrate crystals in knee meniscus by dual-energy computed tomography
BACKGROUND Calcium pyrophosphate dihydrate (CPPD) crystals are commonly observed in osteoarthritic joints. The aim of our study was to investigate the efficacy of a dual-energy computed tomography (DECT) for detecting CPPD crystals in knee meniscus. METHODS Twenty-six patients undergoing primary total knee arthroplasty were included in the study. Radiographs of knee joint and synovial fluid s...
