Abstract:
This invention describes a flexible radiation probe 2 which has a pair of insulated gate field effect transistors integrated into the same substrate each having a gate, source and drain. The transistors are mounted at the end of a flexible circuit board 6. The flexible circuit board has conductive tracks 16 which connect the gate, source and drains of each of the transistors to a connection at an opposite end of the flexible circuit board 6. This connection end may then be connected to a suitable differential biasing circuit for biasing the transistors, and a circuit for reading the differential threshold voltages of the transistors. This differential threshold voltage being indicative of radiation received by the transistors when exposed in the bias mode. The flexible circuit 6 allows the probe 2 to be used in catheters or similar medical equipment.
Abstract:
A portable dosimeter comprising a radiation detector, arithmetic processing means which digitally processes the output signals of said radiation detector, and means which produces the result of processing by said arithmetic processing means. This dosimeter is further comprised of means which stores exposure history data of individuals and exposure control values, and an interface which is connected to said memory means and to said arithmetic processing means and which inputs and outputs data relative to an external device. The arithmetic processing means performs the exposure control calculation for an individual relying upon output signals from the radiation detector and signals read from said memory means, in order to carry out in real time the daily control, weekly control and monthly control of the individuals to perform perfect control of the individuals against exposure.

Abstract:
Described is a method and system that facilitates triage of thousands to millions of potential patients within a relatively short period of time by scanning of a substrate of a designated card issued to a victim. The method and the system comprise a plurality of noninvasive self-testing test devices located at a plurality of remote peripheral self-testing sites, and each one of the plurality of noninvasive self-testing test devices facilitates self-testing of the substrate of the designated card. Each of the plurality of noninvasive self-testing test devices provides test results of the scan of the substrate of the designated card, and the potential patients are identified, then subsequently screened and triaged based upon the test results of the scan of the substrate of the designated card.
Abstract:
The present invention relates to an arrangement (205, 2051, 2052, 2053, 2054, 2055, 305, 405) for measuring a X-ray dose parameter. The arrangement comprises a detector (3051, 3052) for detecting said x-ray dose. The arrangement is configured to be positioned in a position adjacent to an x-ray source (201) arranged to generate a ray formation having a primary ray portion for radiating an object (206), wherein said position is chosen in such a way that the interference with a reproduced image is reduced or eliminated.
Abstract:
A radiation dosimeter includes: a radiation detector that detects radiation; a shield member that covers the radiation detector; and a microcomputer that calculates a dose of radiation based on energy of radiation detected by the radiation detector and a conversion factor that is defined in accordance with energy of radiation scattered by the shield member. The radiation detector detects the radiation scattered by the shield member. With the radiation dosimeter, the detection sensitivity to radiation can be improved and the accuracy of dose measurement can be improved without complicating the structure.
