Abstract
Magnetic resonance imaging (MRI) with a continuously moving table (CMT) represents a novel method allowing for the seamless acquisition of an extended field-of-view in the z-direction. One option to realize CMT MRI from a technical point of view is based on very fast sequences like echo planar imagi...

Abstract
A growing body of evidence as to the benefits of intensity-modulated radiotherapy (IMRT) has led to the recommendation for its adoption as a treatment option for cancer patients within the UK. Routine clinical implementation of this technology has been slow. One of the causal factors was identified...

Abstract
We investigated the radiation dose to the operator performing interventional procedures in 43 patients with the aid of a monoplane flat detector-based angiography system.
During the procedures we recorded the number of radiographic frames and the radiographic conditions. After treatment we recorded...

Abstract
While applying identical exposure values the NIP system for all features revealed superior ratings to those of the PIP system (AUC (VGC) values ranged from 0.81 for "cardiac silhouette" to 0.92 for "trachea"). Even when reducing mAs by 50 % in the NIP images all features were rated better compared w...

Abstract
Understanding the effects of ionizing radiations are key to determining their optimal use in therapy and assessing risks from exposure. The development of microbeams where radiations can be delivered in a highly temporal and spatially constrained manner has been a major advance. Several different ty...

Abstract
Microbeam radiation therapy (MRT) uses highly collimated, quasi-parallel arrays of X-ray microbeams of 50-600keV, produced by third generation synchrotron sources, such as the European Synchrotron Radiation Facility (ESRF), in France. The main advantages of highly brilliant synchrotron sources are a...

Abstract
To examine the common learning styles of radiography students during clinical practice.
Descriptive research methodology, using a single self-report questionnaire, helped to identify common learning styles of radiography students during clinical practice.
The results indicated that 3 learning styles...

Abstract
In spite of the sharp increase in both private and government R&D fund, the number of newly approved medicines for market had decreased since the 1990s. This is attributed to a large extent to the bottleneck in the critical path arising from the great disparity between animal model in pre-clinical t...

Abstract
We interviewed 3 technologists who were highly skilled in mammography, and 14 factors were retrieved by using brainstorming and the KJ method. We then applied Interpretive Structural Modeling (ISM) to the factors and developed a hierarchical concept structure. The result showed a six-layer hierarchy...

Abstract
No significant difference (two-tailed P = 0.962, Welch's t-test) was observed between averaged AUC values from radiographers (0.76, range 0.85-0.62) and radiologists (0.75, range 0.86-0.62). CONCLUSION: Film-reading ability of radiographers in detecting gastric cancer during screening X-ray examinat...

Abstract
Limiting unnecessary occupational radiation exposure is a critical issue in radiology. There was a statistically and clinically significant association between radiation safety education and the decreased number of adult fingers seen on PICU chest radiographs. This study provides preliminary evidenc...

Abstract
We evaluated methods of calculation of collimator scatter factors (S(c)) in a linear accelerator equipped with MLC instead of lower collimators. Routinely,S(c) is calculated from rectangular fields shaped by upper and lower jaws in the linear accelerator. However, this calculation method should not...

This paper focuses on the legal implications in terms of duties and responsibilities for radiologists and radiologic technologists of independent pre-reading of mammograms by radiologic technologists, so patients could be discharged without being seen by a radiologist. Pre-reading could be effectuat...

Abstract
Differences in dose distributions were small between segmented and wedge techniques based on 3D studies. Because of small motion amplitude of the chest in the 4D CT studies (1.8 mm +/- 0.9 mm), target coverage was reduced by < 5% due to breathing motion. Differences between 3D and 4D dose calculatio...

Abstract
The reports of the CT scans showed significantly less variation. The consent of all 3 raters was achieved in 79.4 vs. 65.1 % of cases. The Kappa values were 0.56 and 0.29, respectively. Poor results were obtained especially for the medial pedicle wall (consent 70.0 vs. 50.0 %). The influence of the...

We measured operator exposure dose during IVR using a thermoluminescence dosimeter. The results revealed the dose equivalent to the operator's hands and fingers to be higher than that of other parts, although the effective dose for the operator was low. Moreover, we looked into the factors that affe...
