Peripheral dose measurement with a MOSFET detector.
The accuracy of a MOSFET dosimetry system with respect to peripheral therapeutic doses from high-energy X-rays has been evaluated. The results have been compared with ionisation chamber measurements in the same peripheral regions of the beam. For 6 MV and 18 MV X-ray beams, the MOSFET system in the high-sensitivity mode produces reproducibility of dose measurement with relative standard deviati...
متن کاملSmall field electron beam dosimetry using MOSFET detector
The dosimetry of very small electron fields can be challenging due to relative shifts in percent depth-dose curves, including the location of dmax, and lack of lateral electronic equilibrium in an ion chamber when placed in the beam. Conventionally a small parallel plate chamber or film is utilized to perform small field electron beam dosimetry. Since modern radiotherapy departments are becomin...
متن کاملExtended ratio edge detector for despeckled SAR image evaluation
Synthetic aperture radar (SAR) images due to the usage of coherent imaging systems are affected by speckle. So lots of despeckling filters have been introduced up to now to suppress the speckle. Hence, objective and subjective evaluation of the denoised SAR images becomes a necessity. Thereby lots of objective evaluating estimators are introduced to evaluate the performance of despeckling filte...
متن کاملInconsistencies in Edge Detector Evaluation
In recent years, increasing e ort has gone into evaluating computer vision algorithms in general, and edge detection algorithms in particular. Most of the evaluation techniques use only a few test images, leaving open the question of how broadly their results can be interpreted. Our research tests the consistency of the receiver operating characteristic (ROC) curve, and demonstrates why consist...
متن کاملA Distance Detector with a Strip Magnetic MOSFET and Readout Circuit
This paper presents a distance detector composed of two separated metal-oxide semiconductor field-effect transistors (MOSFETs), a differential polysilicon cross-shaped Hall plate (CSHP), and a readout circuit. The distance detector was fabricated using 0.18 μm 1P6M Complementary Metal-Oxide Semiconductor (CMOS) technology to sense the magnetic induction perpendicular to the chip surface. The di...
