Abstract
We report on high frame rate X-ray imaging tests with the Medipix2 single photon counting detector (single frames contain 256times256 pixel, 55 mum pitch, 13 bit counter) bump-bonded to a 300 mum thick silicon pixel detector. Image data are readout serially at a maximum frequency of 86 MHz, and each image frame corresponds to about 1 Mbit. After implementing a new version of the dedicated Medisoft 4.1 software for the operation of the Medipix2 imaging system, the maximum possible frame rate increased from a few frame per second up to 51 fps (10% duty cycle). Dynamic imaging tests have been made by irradiating with a X-ray tube (25 kV, 1 mA) an absorbing edge being translated at constant speed. Applications of this new option for the Medipix2 imaging system are in the fields of cineradiography, dynamic X-ray imaging, and synchrotron radiation imagingI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
