Measurement of stereotactic beam data of 9 MV X-rays using diode detector

Background: Radiosurgery is a focal brain irradiation technique that delivers, usually in a single session, high dose of ionizing radiation. The presence of lateral electronic disequilibrium and steep dose gradients in small fields demands special attention to the selection of a suitable detector with respect to its size, composition and response. Materials and Methods : Small circular fields w...

Cvd-diamond-based Position Sensitive Photoconductive Detector for High-flux X-rays and Gamma Rays

A position-sensitive photoconductive detector (PSPCD) using insulating-type CVD diamond as its substrate material has been developed at the Advanced Photon Source (APS). Several different configurations, including a quadrant pattern for a x-ray-transmitting beam position monitor (TBPM) and 1-D and 2-D arrays for PSPCD beam profilers, have been developed. Tests on different PSPCD devices with hi...

Characterization of a scintillating GEM detector with low energy x-rays.

A two-dimensional position-sensitive dosimetry system based on a scintillating gas detector is being developed with the aim of using it for pre-treatment verification of dose distributions in charged particle therapy. The dosimetry system consists of a chamber filled with an Ar/CF(4) scintillating gas mixture, inside which two cascaded gas electron multipliers (GEMs) are mounted. A GEM is a thi...

X-rays and technology as metaphor.

man imagination. It is possible to trace developments in the use of x-rays in medicine over the century or so since their discovery by Wilhelm Conrad Röntgen. It is equally possible to recognize that radiography and other technologies have provided a mirror for the society in which they have been used. In other words, although technology changes society, society, in its response to technology, ...

CMOS X-rays detector array based on scintillating light guides

This paper describes a pixel imaging array consisting in 400 m × 400 m photodiodes fabricated in CMOS technology. An array of scintillating CsI:Tl crystals is placed above the photodiodes. These crystals are encapsulated in aluminum walls, forming a light path that guides the visible light produced by the scintillating crystal into the photodiodes. In this way, the X-ray energy is first convert...
