PURPOSE To evaluate gold marker displacement due to needle insertion during HDR-brachytherapy for therapy of prostate cancer. PATIENTS AND METHODS 18 patients entered into this prospective evaluation. Three gold markers were implanted into the prostate during the first HDR-brachytherapy procedure after the irradiation was administered. Three days after marker implantation all patients had a C...

High dynamic range (HDR) image and video technology has recently attracted a great deal of attention in the multimedia community, as a mean to produce truly realistic video and further improve the Quality of Experience (QoE) of emerging multimedia services. In this context, measuring the quality of compressed HDR content plays a fundamental role. However, full-reference (FR) HDR visual quality ...

We previously proposed the Orthogonal Code Hopping Multiplexing(OCHM) scheme as a new statistical multiplexing scheme in synchronous downlink and applied the OCHM scheme to IS-95 and Wideband CDMA. OCHM enables a large number of users to share the limited number of code channels through statistical multiplexing. In this paper, we compare OCHM with HDR through link-level simulation. OCHM outperf...

The severity of most human birth defects is highly variable. Our ability to diagnose, treat and prevent defects relies on our understanding of this variability. Mutation of the transcription factor GATA3 in humans causes the highly variable hypoparathyroidism, sensorineural deafness and renal dysplasia (HDR) syndrome. Although named for a triad of defects, individuals with HDR can also exhibit ...

The main objective of this paper is to verify test methodologies for the assessment of high dynamic range (HDR) video. To achieve this, a next generation HDR monitor by Dolby Laboratories was used to display professionally produced HDR content. Two complementary approaches for subjective assessment of HDR video were then designed and carried out at the European Broadcast Union and Ecole Polytec...

Medical imaging devices often capture the raw data with high precision, producing high dynamic range (HDR) images. To visualize HDR images on regular displays, there has been an increasing number of tone mapping algorithms developed in recent years that convert HDR to low dynamic range (LDR) images. To visualize HDR medical images, a so-called “windowing” procedure is typically employed by whic...

BRCA1 plays a critical role in homology-directed repair (HDR) of DNA double strand breaks, and the repair defect of BRCA1-mutant cancer cells is being targeted with platinum drugs and poly (ADP-ribose) polymerase (PARP) inhibitors. We have employed relatively simple and sensitive assays to determine the function of BRCA1 variants or mutants in two HDR mechanisms, homologous recombination (HR) a...

High Dynamic Range (HDR) video offers the possibility, for the first time, of capturing, storing, manipulating, and displaying dynamic real-world lighting. This gives a step change in viewing experience, for example the ability to clearly see the football when it is kicked from the shadow of the stadium into sunshine. An HDR video camera now exists which is capable of capturing 20 f-stops at fu...

While tone mapping operation of high dynamic range (HDR) images for realistic display is commonly researched, scientific visualization for analysing scene luminance within HDR image has much less attention from researches. This paper has presented and implemented an approach for the reproduction and visualization of the colour information in HDR images. We attempt several simple colour visualiz...

High dose rate (HDR) endobronchial brachytherapy is a palliative treatment for symptomatic airway obstruction by malignant tumours. We report a novel use of HDR brachytherapy for treating nonmalignant bronchial obstruction. The patient had a metal stent placed in a reconstructed airway after a bronchial tear to ensure patency. Granulation tissue formation in and around the stent caused symptoma...
