    Abstract: Apparatus for capturing two-dimensional images created by radioactive emanations, such as gamma rays, from a radioactive source, comprises a collimator (14), a two-dimensional array of scintillating fibers (23) and position encoding apparatus (18). The scintillating fibers are located at preselected x and y positions in an x-y plane. The position encoding apparatus comprises banks of photon detectors (28, 30) and a network of optical fibers (26) which are connected to the photon detectors in a manner which encodes the x-y coordinates of the scintillating fibers, and a signal processor for generating position signals indicative of the encoded position of an active scintillating fiber.

    Abstract: The invention concerns a device for measuring exposure of a solid state image sensor (1). Said detector (1) comprises a first surface (1a) exposed to an ionising radiation (R1) representing the image. It releases through another surface (1b) opposite the first (1a) an unabsorbed ionising radiation (R2). The measuring device is designed to be placed near the other surface and to be exposed to the unabsorbed ionising radiation (R2). It comprises at least one optical fibre (11) emitting a visible or nearly visible radiation, obtained by conversion in the optical fibre, towards at least a sensing device (13), the visible or nearly visible radiation representing the unabsorbed ionising radiation. The sensing device (13) generates a signal representing the image sensor exposure. The invention is in particular applicable to X-ray image sensors.

    Abstract: The present invention relates to a system (10) for measuring a dose of ionizing radiation received by a pre-determined part of the body during radiotherapy or interventional procedures. The system (10) comprises: a) a light guide (1), which under the influence of ionizing radiation undergoes measurable and quantifiable physical changes; b) a detector system (5) which allows the recording and quantification of the signal emitted by the light guide (1); and c) a control unit (6) which is adapted for calculating a dose of ionizing radiation previously or simultaneously received by the light guide (1) on basis of said response signal. The light guide (1) is coated over at least part of its length with a coating comprising a first component (2) acting as a place dependent spectral filter and a second component (3) 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. An algorithm in the control unit (6) relates the total amount of light (proportional to the dose received at each location), as recorded by the detector system (10), into a dose distribution along the coated length of the light guide (1). The invention also relates to a method for measuring a received dose of ionizing radiation using a single light guide (1) with a double component coating, along at least part of the length of the light guide (1).
