Breast cancer is the most common occurring in women worldwide. To guide current breast screening program, level of knowledge about should be evaluated. This study aims to ascertain including risk factors, signs and symptoms, early detection methods, especially mammography screening.The was conducted among 1353 Jordanian from public using a self-administered questionnaire. Responses test were summed for an overall score. Comparisons between socio-demographics knowledge, attitude practice also...
Abstract The purpose of this work is to present a body size and tube voltage dependent correction scheme for the Hounsfield Unit, HU, in medical X-ray Computed Tomography imaging. Boltzmann photon transport equation was employed study interaction with bulk water CT Experimentally measured output phantoms attenuation cross sections were derivation beam intensity A Somatom Emotion scanner from Siemens electron density CIRS acquire images different sizes tissue materials located at depths...
Abstract Introduction Patient positioning is an essential consideration for the optimisation of radiation dose during CT examinations. The study objectives seek to explore effects vertical off‐centring, localiser direction (0° and 180°), phantom (supine prone) on dose, using three different tube voltages in multidetector computed tomography (MDCT) imaging. Methods trunk a PBU‐60 anthropomorphic was imaged Discovery CT750 HD – 128 slice (GE Healthcare). Images employing 0° 180° localisers...
Background: This study investigates the effects of vertical off-centring, localiser direction, tube voltage, and phantom positioning (supine prone) on computed tomography (CT) numbers radiation dose. Methods: An anthropomorphic was scanned using a Discovery CT750 HD—128 slice (GE Healthcare) scanner at different voltages (80, 120, 140 kVp). Images employing 0° 180° localisers were acquired in supine prone positions for each off-centring (±100, ±60, ±30 mm from iso-centre). CT displayed...

Patient positioning is known to impact CT number and patient dose. The aim of this study was report current practice the accuracy knowledge radiographers in Australia regarding inappropriate centring during CT.
Abstract Objectives: This pilot experimental study explores the effect of vertical off-centring on CT numbers in combination with various tube voltages and phantom sizes. Methods: A CIRS Model 062 Electron Density Combined Head Body underwent imaging using a Siemens Emotion 16-slice GEMINI GXL scanners. Uniformity was evaluated as function (20, 40, 60, 80 mm above gantry iso-centre) different sizes voltage for ROI positions across X Y axis each phantom. number change assessed by comparing...
