Abstract:
The present invention relates to a semiconductor sensor having a delay line structure and a radiation measurement system and measurement method using the same. The semiconductor sensor includes a semiconductor substrate; a first electrode formed on the upper part of the semiconductor substrate in a single wire electrode structure, an upper layer which is formed on the upper part of the first electrode to prevent the distortion of a high frequency signal and signal loss, and a second electrode which is formed on the lower part of the semiconductor substrate by using a conductive material. The first electrode includes a delay line which is arranged in a zigzag pattern on the upper surface of the semiconductor substrate and first and second cathodes which are connected to both ends of the delay line so as to be applied to a large area radiation imaging system, reduce the number of components of the radiation imaging system, and save production costs.

PURPOSE: A method and a system for processing a 3D distribution image of radiation are provided to enhance reduce measuring time by increasing detection efficiency so that stress in which a patient or a creature is gotten can be reduced. CONSTITUTION: A system(100) for processing a 3D distribution image of radiation comprises an image measuring part(110), a signal amplifying processor(120), a mode selector(125), a data storage unit(130), a data converter(140), an image reconstructing unit(150), and a display unit(160). The image measuring part comprises a plurality of position sensitive type detectors for measuring a radiation source. The signal amplifying processor receives electrical signals generated from the signal amplifying processor, thereby outputting mode signals by selecting a detection mode according to a size and a position. The data storage unit stores a size of radiation source energy, generating time, radiation source generating position signals, and the mode signals received from the signal processing unit as a series of items. The data converter converts the data stored in the data storage unit into interaction mode data. The image reconstructing unit reconstructs the converted data to 3D distribution images.
