The solid state active detectors, widely used for conventional radiotherapy, such as diamond detectors (DD) and diodes may be attractive tools also in dosimetry of therapeutic proton beams. Diodes are broadly applied in oncology clinics and routinely used for in-vivo dosimetry [1, 8]. These real-time detectors are rugged, relatively inexpensive and provide on-line readings, what allows for quic...

Accidental hypothermia was studied in 11 patients, five of whom died. This condition occurs spontaneously, usually in a cold environment, and should be suspected in the comatose hypotensive patient. It is easily missed because regular clinical thermometers do not record extremely low body temperatures. It is distinguished from other forms of hypothermia by the very low body temperature and by t...

abstractbackground: although electronic portal imaging devices (epids) have originally developed for positioning verification, they can also be used for dosimetric purposes. in the current work, the dose response of minimum detectable thickness of a scanning liquid filled ion chamber epid, slic-epid, and the variation of transmitted dose with the shift of inhomogeneity inside of phantom was als...

abstract background: for treatment verification in radiation therapy. several physical characteristics of scanningliquid filled ionization chamber epid (slic-epid) including: extra build-up layer,reproducibility and uniformity, and noise level were investigated.electronic portal imaging devices (epids) have found an outstanding positionmaterials and methods: equilibrium, 1-30 mm white water mat...
