The potential risks of radiation exposure associated with computed tomography (CT) imaging are reason for ongoing concern for both medical staff and patients. Radiation dose reduction is, according to the as low as reasonably achievable principle, an

The purpose of this 12 month randomized exercise intervention was to determine the effect of a block-periodized multipurpose exercise program on bone mineral density (BMD) and parameters of the metabolic syndrome (MetS) in early post-menopausal women

A phantom consisting of water- and bone-equivalent solid materials was devised to test peripheral bone densitometry systems. A circular cross section with a diameter of 60 mm was chosen, with the sides flattened by 1 cm to model the forearm. Three in

We examined whether the effect of multipurpose exercise can be enhanced by whole-body vibration (WBV). One hundred and fifty-one post-menopausal women (68.5 ± 3.1 years) were randomly assigned to three groups: (1) a training group (TG); (2) training

Flat detectors (FDs) have been developed for use in radiography and fluoroscopy to replace standard X-ray film, film-screen combinations and image intensifiers (II). In comparison to X-ray film and II, FD technology offers higher dynamic range, dose

Whole body vibration (WBV) training is a new approach which is currently discussed in the context of reducing the risk of osteoporotic fractures. The study was undertaken to determine the effect of one-year WBV exercise on bone mineral density (BMD)

Various approaches to reduce dose to the female breast in thoracic CT have been investigated. We evaluated the potential for reduction of dose to the breast by optimal choice of the X-ray spectra. The effect of X-ray energy variation on dose to the f

The objective of this study was an integrated cross-sectional investigation for answering the question whether differences in bone mineral density in elderly postmenopausal women are associated with differences in habitual physical activity and unspe

The aim was to provide an assessment of temporal resolution based on the temporal modulation transfer function (t-MTF). The t-MTF was generated by an edge spread function in the temporal direction (t-ESF). Therefore, a rod was moved on a linear path
