    摘要: The present invention may provide a particle or radiation detector or imager which may be used for accurate recording of medical (2-D) X-ray images. The imager includes at least one detector panel. The detector panel includes a microgap detector with an array of pixel electrodes of a novel form. Each pixel electrode is insulated from a planar cathode by means of an insulating layer. Each pixel electrode is connected to an underlying contact by means of a via hole in the insulating layer. The insulating layer is preferably conformal with the electrodes. The underlying contact is connected to an electronic measuring element which preferably lies underneath the electrode and is about the same size as the electrode. The measuring element may be a storage device, a digital counter or similar. A switching transistor is connected to the measuring device. The switching transistor may be a thin film transistor. Alternatively, both measuring element and transistor may be formed in a single crystal semiconductor, e.g. a VLSI, and a complete imager formed from several detector panels in an array. The drift electrode of the microgap detector preferably includes a photocathode. The photocathode may be directly evaporated onto a phosphor.

    摘要: A nanodosimeter device (15) for detecting positive ions induced in a sensitive gas volume by a radiation field of primary particle, comprising an ionization chamber (10) for holding the sensitive gas volume to be irradiated by the radiation field of primary particles; an ion counter system connected to the ionization chamber (10) for detecting the positive ions which pass through the aperture opening and arrive at the ion counter (12) at an arrival time; a particle tracking system for position-sensitive detection of the primary particles passing through the sensitive gas volume; and a data acquisition system capable of coordinating the readout of all data signals and of performing data analysis correlating the arrival time of the positive ions detected by the ion counter system relative to the position sensitive data of primary particles detected by the particle tracking system. The invention further includes the use of the nanodosimeter for method of calibrating radiation exposure with damage to a nucleic acid within a sample. A volume of tissue-equivalent gas is radiated with a radiation field to induce positive ions. The resulting positive ions are measured and compared with a determination of presence or extent of damage resulting from irradiating a nucleic acid sample with an equivalent dose of radiation.
