Rectourethral Fistula following LDR Brachytherapy
Urologia Internationalis, 2009Modern LDR brachytherapy has drastically reduced rectal toxicity and decreased the occurrence of rectourethral fistulas to <0.5% of patients. Therefore, symptoms of late-onset sequelae are often ignored initially. These fistulas cause severe patient morbidity and require interdisciplinary treatment.

LDR to HDR Conversion Based on Histogram Extension
2021 IEEE International Conference on Consumer Electronics-Taiwan (ICCE-TW), 2021We present a method of generating high dynamic range image. Our input is low dynamic range image. We transform an input image into HSI color space, separating the color and intensity information. Then dynamic range of intensity is extended from [0, 255] to [0, 1023] and a Butterworth filter is applied to the histogram which is set as the target ...

A response to LDR 2 LDR: KNEX 2 U
Journal of Leadership Studies, 2009AbstractAn act of leadership is always an act of practical theory. We lead because we hold visions of the world as it ought to be, because of the not yet, because of the potential that we see in ideas and people. Yet, there still exists a perceived binary between leadership theory (in the strong sense) and leadership practice, a binary that divides ...

HDR Versus LDR Gynecological Brachytherapy Revisited
Medical Dosimetry, 1993Despite the obvious breakthrough of high dose-rate (HDR) afterloading systems on the gynecological brachytherapy market, questions still remain regarding the transfer of available expertise gained throughout the last 80 years with low dose-rate (LDR) radium and cesium, especially regarding the conversion of LDR total dose into equivalent HDR dose per ...

A response to LDR 2 LDR: Theory and practice working together
Journal of Leadership Studies, 2009AbstractAn act of leadership is always an act of practical theory.

LDR Lite Benchmark: Description of the Core Model
International Conference on Physics of Reactors (PHYSOR 2024)We alleviate the lack of detailed, design-specific SMR-benchmarks by providing the first specifications of the LDR lite benchmark.This benchmark is based on the public version of the LDR-50 reactor design, developed at VTT since 2020 for low temperature heat production applications.The main characteristics of this 50 MWth integrated pressure water ...

Response of an LDR to Light's Spatial Structure
Frontiers in Optics + Laser Science 2023 (FiO, LS), 2023An LDR's response is known to be dependent on light intensity and wavelength. In this work, we show via simulations and experiment that its behavior is also affected by the spatial structure of incoming light.

In-phantom calibration of Selectron-LDR sources
Radiotherapy and Oncology, 1990Source strength measurements were performed for cesium-137 spherical sources of nine Selectron-LDR remote afterloading systems in The Netherlands. The mean reference air kerma rate of a set of sources was obtained from air kerma rate measurements in a phantom at a distance of about 5.5 cm from a large number (24 to 30) of sources.

Low-dose-rate (LDR) intracavitary brachytherapy for the uterine cervix was a standard treatment modality in the first half of the twentieth century. High-dose-rate (HDR) intracavitary brachytherapy was developed to overcome some drawbacks of LDR brachytherapy (e.g., exposure of the medical staff and long treatment time).
