摘要： A radiation detector (100) includes an insulating substrate (110), which includes a material that undergoes a change in an electrical property when subjected to ionizing radiation. A conductive film (112) is disposed in relation to a surface of the substrate. The conductive film (112) has a resistance that is a function of a state of the electrical property. A resistance measuring device measures resistance across the conductive film (112). The resistance measured by the resistance measuring device indicates an amount of ionizing radiation to which the substrate (110) has been subjected. In a method of determining exposure to a type of radiation, a boron nitride substrate is exposed to a radiation environment. A resistance is measured across a conductive film disposed in relation to the boron nitride substrate. Radiation exposure is calculated as a function of the resistance.

A sensor system may be provided with integrated signal processing electronics, for monitoring a change in differential channel current ID, indicative of radiation dose, and an integrated negative bias generator for automatic pre-charging from a low voltage power source. Optionally, the system may be coupled to a wireless transmitter. A compact wireless sensor System on Package solution is presented, suitable for dosimetry for radiotherapy or other biomedical applications.

摘要： The present invention is an indirect AMFPI wherein a phosphor such as a structured cesium iodide (CsI) is used to convert x-ray energy to optical photons or a charge, which is then detected by a two-dimensional array of either thin-film transistors (TFTs) such as an amorphous a-Se TFTs or a photodiode array. A scanning control circuit generates pulses to turn on the TFTs one row at a time, and thus the charge in the individual arrays is transferred from the TFT to one or more external charge-sensitive amplifiers. The charge-sensitive amplifiers are shared by all the pixels in the same column. The two-dimensional array can be read in real time.
