Problems solved by technology

For example, for technologies such as ion chamber arrays implemented on a PCB or monolithic silicon, the cost of the pixel array is primarily a function of area, while the cost of the corresponding readout electronics increases with the number of pixels

Abstract

A radiation sensor (1) comprises a radiation detector array (21) comprising a plurality of pixels (33, 34); at least two readout connectors (11, 12) having a plurality of contacts, each of said readout connectors being configured for receiving a readout module; a routing circuit (10) having conductors configured for routing electrical signals from each of said plurality of pixels (33,34) to a corresponding contact of one of said readout connector (11,12). The plurality of pixels is grouped in two or more groups of pixels (33, 34), at least two pixels of a first group of pixels (33) being separated by at least one pixel from another group of pixels (34) in the radiation detector array (21). The routing circuit is configured for leading pixels of said first group of pixels (33) to a first readout connector (11), and pixels from said other group of pixels (34) to a second readout connector (12). A corresponding method associated thereto is also disclosed.

Description

technical field [0001] The invention relates to the field of radiation sensors. In particular, the present invention relates to a radiation sensor having circuitry for routing electrical signals from an array of radiation detectors to a plurality of electronic readout circuits. Background technique [0002] Detectors comprising a one-dimensional or two-dimensional array of detector pixels are commonly used for radiation imaging, eg in medical applications such as nuclear medicine, radiology, radiotherapy or proton therapy. In a radiation detector array, each pixel may be adapted to generate a signal, such as a current, charge or potential, indicative of a dosimetric or radiation amount associated with radiation incident on that pixel. For example, silicon diodes and ionization chambers may be commonly used in pixel elements for radiation detection applications. [0003] Pixel signals can be read out in parallel using a front-end electronics subsystem comprising multiple mu...
