Background: This paper presents a method to reduce radiation exposure during mammography by analysing the doses to ipsilateral and contralateral breasts and to adjacent organs by evaluating material-dependent shielding performance.  Materials and Methods: Six target-filter combinations (Mo-Mo, Mo-Rh, Rh-Rh, Rh-Mo, W-Mo, W-Rh) were tested by measuring the doses delivered to the breasts and adjac...

BACKGROUND Fluoroscopic guidance may be utilized in some bronchoscopic procedures, including ultrasound-guided bronchoscopy for investigation of peripheral pulmonary lesions. Some authors have suggested this procedure may be performed without fluoroscopy, to minimize risks due to radiation exposure. However, the radiation dose has never been quantified, so the risk remains unknown. OBJECTIVE ...

X-Ray Detection and Shielding In article number 2206782, Jian-Qiang Wang, Jian Lin, co-workers demonstrate a bifunctional platform for X-ray detection shielding, which is realized by stepwise crystallization of millimeter-scale thorium cluster single crystals. The judicious synergy between high-Z cations 3-(pyridin-4-yl)benzoate ligands gives rise to radiochromic nanocluster, whose attenuation ...

Contact person: [email protected] INTRODUCTION There has been much recent research interest in microclimate cooling for individuals working in hot climates whilst wearing protective clothing (Bomalaski et al. 1995; Chen et al. 1997; Cheuvront et al. 2003; Chinevere et al. 2008). Attempts have been made to develop cooling garments that augment convective (air cooled garments), conductive...

It has recently been suggested that lycra garments are helpful for children with cerebral palsy (CP). Twelve children, with athetosis, ataxia, and spasticity, were fitted with lycra garments (Kendall-Camp UK Ltd). Scores on the Paediatric Evaluation of Disability Inventory (PEDI) scales were determined before and after wearing the garment for at least 6 hours a day for 6 weeks. Five children wi...

The shielding of positron emission tomography (PET) and PET/CT (computed tomography) facilities presents special challenges. The 0.511 MeV annihilation photons associated with positron decay are much higher energy than other diagnostic radiations. As a result, barrier shielding may be required in floors and ceilings as well as adjacent walls. Since the patient becomes the radioactive source aft...

BACKGROUND Symptoms of Parkinson's disease (PD) include bradykinesia, gait abnormalities, balance deficits, restless leg syndrome, and muscular fatigue. Compression garments (CG) have been shown to improve performance in athletes by increasing venous return and reduce lactic acid. OBJECTIVE Assess the effect of compression garments on the performance of 3 standardized functional tests in pers...
