A method of analyzing a plurality of biopsy cores extracted from a plurality of respective biopsy locations in a prostate is disclosed. The method comprises: measuring a level of a chemical element in each of the biopsy cores, and generating a chemical element map of at least a portion of the prostate based on the levels and the respective biopsy locations. In some embodiments, the method determines at least one additional biopsy location for a future biopsy in the prostate.

A nanodosimeter device () for detecting positive ions induced in a sensitive gas volume by a radiation field of primary particle, comprising an ionization chamber () 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 () for detecting the positive ions which pass through the aperture opening and arrive at the ion counter () 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.

Imager or particle or radiation detector and method of manufacturing the same

The present invention may provide a particle 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 preferable 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.

A method for the detection of a nitrogenous explosive material in an object is provided which makes use of nuclear resonance absorption. The object to be tested is placed between a 9.17 MeV .gamma.-rays source and an .gamma.-rays detector holding a nitrogen medium. The total and the non-resonant attenuation of the .gamma.-rays flux is read by the detector and fed into a recorder. From the measured attenuation the net non-resonant attenuation is calculated and the amount of a nitrogenous explosive present in the object is determined therefrom. Also provided by the invention is a system for detecting a nitrogenous explosive in an object.
