摘要： A radiation detector including a chamber capable of being filled with an ionizable and scintillating substance, and a radiation entrance arranged such that radiation can enter said chamber partly for ionizing said ionizable and scintillating substance, partly for being converted into light therein, is disclosed. The detector further includes a light detector for detection of said light, and an electron avalanche detector for avalanche amplification and detection of electrons released as a result of the ionization. Further, there are provided means for correlating detected light and detected electrons, which are derivable from a single radiation photon; and means for producing a signal from the correlated detected light and detected electrons. The detector is particularly suitable for positron emission tomography (PET).

摘要： A light detecting unit of an alpha ray observation device observes an alpha ray by measuring generated light that is generated by the alpha ray produced in a region of a to-be-measured object. The light detecting unit has a travel direction changing unit that changes the direction of travel of generated light, a light detector that detects direction-changed light, which is the generated light after the direction of travel is changed, and a shielding member that shields the light detector from radiation and has a portion that is provided on the line from the to-be-measured object to the light detector. The shielding member may also surround the perimeter of the light detector and have an opening to allow generated light to reach the travel direction changing unit.

摘要： An apparatus and method for in vivo and ex vivo control, detection and measurement of radiation in therapy, diagnostics, 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.
