    Abstract: The present invention provides a radiation detector which comprises a tube and detector elements distributed over the tube. Such an arrangement can be used to provide information on a radiation beam prior to interaction with a patient and after interaction with the patient. The detector is particularly compact and therefore suited to use with apparatus where space is restricted. By a particular arrangement of detectors and optical fibres, the detector can provide data at all angles of rotation.

    Abstract: An apparatus and method for in vivo and ex vivo control, detection and measurement of radiation in therapy, diagnostcs, and related applications accomplished through scintillating fiber detection. One example includes scintillating fibers placed along a delivery guide such as a catheter for measuring applied radiation levels during radiotherapy treatments, sensing locations of a radiation source, or providing feedback of sensed radiation. Another option is to place the fibers into a positioning device such as a balloon, or otherwise in the field of the radiation delivery. The scintillating fibers provide light output levels correlating to the levels of radiation striking the fibers and comparative measurement between fibers can be used for more extensive dose mapping. Adjustments to a radiation treatment may be made as needed based on actual and measured applied dosages as determined by the fiber detectors. Characteristics of a radiation source may also be measured using scintillating materials.

    Abstract: The invention relates to detection of radiations by means of any appropriate devices, particularly those comprising small probes used e.g. in diagnostics or in surgery, or in biomedical or pharmacological research. The aim of the invention is to improve the performance of probes and their working methods in terms i.a of background, miniaturization sensitivity and selectivity. In this respect, the invention concerns a Method of detecting, locating and/or analyzing a radioactive source(s) emitting charged or neutral particles in a material, particularly a biological tissue, consisting essentially in using scintillating fiber(s) having a ratio L (Length)/r (range of the particles emitted by the source)≧2, d (diameter)/r≦5, and L/d≧2; scanning the surface of the material with the detection rod; collecting by means of a SiPM, the scintillation light output (SLo) generated by the particles having entered and interacted with the scintillating fiber(s) and emitted at the outlet end; optionally selecting signals SLo corresponding essentially to the particles entering the scintillating fiber(s) in a substantially axial direction (directional sensitivity), that is to say eliminating the particles which angle αp, that is the angle between the axis of the scintillating fiber and the direction of the particles entering the scintillating fiber, is greater than αt (αp> & αt), then which length lp is lower than lt (1

    Abstract: A bundle of drawn fibers that have X-ray scintillating unagglommerated nanocrystallite particles in plastic or glass cores of down to 0.1 micron spacing and claddings of X-ray absorbing compounds in the cladding composition. Optional is a cover to the bundle that blocks light from leaving the bundle at the X-ray side while allowing X-rays to pass into the cores. To image the light exiting the fiber bundle at the sub-micron level, light expansion is preferable using either a lens system or a fiber bundle expander.
