Abstract: A system and method for measuring a dose of ionizing radiation received by a pre-determined part of the body during radiotherapy or interventional procedures. The system comprises: a) a light guide, which under the influence of ionizing radiation undergoes measurable and quantifiable physical changes; b) a detector system which allows the recording and quantification of the signal emitted by the light guide; and c) a control unit which is adapted for calculating a dose of ionizing radiation previously or simultaneously received by the light guide on basis of said response signal. The light guide is coated over at least part of its length with a coating comprising a first component acting as a place dependent spectral filter and a second component including at least one luminescent material, dispersed in a transparent matrix. When exposed to radiation, the luminescent component will emit light with a spectrum depending on the chosen material.

Abstract: The present invention provides a radiation image detecting device which suppresses occurrence of image irregularities and reduction of sharpness by joining a planar light-receiving device and a scintillator panel so that the distance between the planar light-receiving device and the scintillator panel via an adhesive layer is uniform in plane. The present invention also provides a process for producing the radiation image detecting device. The radiation image detecting device includes, in order, a scintillator panel including a support and a scintillator layer on the support, the scintillator layer having a film-thickness distribution; an adhesive layer; and a planar light-receiving device. In the radiation image detecting device, at least one of the support and the planar light-receiving device bends, so that the scintillator panel and the planar light-receiving device are arranged in plane via the adhesive layer at uniform distance.

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: 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.
