Ring artifacts removal in X-ray-induced acoustic computed tomography

Journal of Innovative Optical Health Sciences, 2022
X-ray-induced acoustic computed tomography (XACT) is a hybrid imaging modality for detecting X-ray absorption distribution via ultrasound emission. It facilitates imaging from a single projection X-ray illumination, thus reducing the radiation exposure ...

Muscle x-ray attenuation is not decreased during experimental bed rest.

, 2013
Muscle X-ray attenuation (MXA) in Hounsfield units (HU) is decreased in dystrophy, aging, and immobilization. We hypothesized a decrease also during bed rest (BR).

Adaptive zooming in X-ray computed tomography [PDF]

Journal of X-Ray Science and Technology: Clinical Applications of Diagnosis and Therapeutics, 2014
BACKGROUND: In computed tomography (CT), the source-detector system commonly rotates around the object in a circular trajectory. Such a trajectory does not allow to exploit a detector fully when scanning elongated objects. OBJECTIVE: Increase the spatial resolution of the reconstructed image by optimal zooming during scanning.

The effectiveness and cost-effectiveness of computed tomography screening for coronary artery disease : systematic review [PDF]

, 2006
Coronary heart disease (CHD) is one of the main causes of mortality and morbidity in the UK and other Western countries. The disease can be asymptomatic until the first event, which may be a fatal myocardial infarction (heart attack).
