Psoriasis Area and Severity Index (PASI) 75 response is currently considered the gold standard for assessing treatment efficacy in moderate-to-severe psoriatic patients. PASI 90 response denotes better clinical improvement compared to PASI 75. Very few studies have assessed if a greater PASI clinical response is associated with greater improvements in(More)
The use of a linear detector array (LDA) in X-ray computed tomography (CT) imaging is well established. Generally the CT system using an LDA operates in a fan-beam configuration. In a non-medical tomography set-up, the X-ray source and detectors are stationary and the object is rotated for scanning. Equi-spaced angular projections over a complete 360 object(More)
Adaptation of a general-purpose digital radiographic scintillator-based linear detector array (LDA) in a continuous-rotate third generation X-ray industrial tomographic imaging system and the resulting artifacts are discussed. Sources of error in the projection data are identified and a mixed approach, involving neighborhood averaging and row-wise(More)
