A high dynamic range (HDR) image uses a large bit depth up to 32-bit per pixel per color channel. Due to hardware limitation, it can neither be captured by conventional camera in a single photo, nor be displayed on a conventional monitor. In this thesis, a software solution of HDR imaging is introduced from the synthesis to the display of high quality HDR images. Contrary to conventional imagin...

A survey of doctors working in two large NHS hospitals identified over 120 laboratory tests, imaging investigations and investigational procedures that they considered not to be overused. A common suggestion in this survey was that more training was required. And, this prompted the development of a list of core principles for high-quality, high-value testing. The list can be used as a framework...

background and purpose: women with low (high) pre-pregnancy body mass index (bmi) recently delivered infants with approximately normal or close to normal birth weights under the high quality of prenatal care. this study estimated the effect of pre-pregnancy bmi when concerns about the effects of different quality levels of prenatal care and the health status of mothers and their infants existed...

Introduction: Quality assurance is essential for obtaining the best achievable tumor control, avoiding unnecessary side effects, accuracy and safety during performing High Dose Rate (HDR) Brachytherapy (BT). Quality assurance is extremely important because HDR BT procedures are performed quickly, with high doses given in a short time period, with little opportunity for correcti...

Background: Foods have been many changes from production to tables and continuous control is necessary to maintain food safety and supply foods with good quality. The aim of this study was to evaluate the quality of some foods with high consumption in Zanjan city during the 5 years from 2009 to 2013. Methods: In a case-control descriptive study with an annually control program during 5 years f...

The emerging network-enabled medical devices impose new challenges for the safety assurance of medical cyber-physical systems (MCPS). In this paper, we present a case study of building a high-level safety argument for a patient-controlled analgesia (PCA) closed-loop system, with the purpose of exploring potential methodologies for assuring the safety of MCPS. 1998 ACM Subject Classification D.2...
