摘要： The invention is directed at an apparatus (10), an imaging device and a method for detecting X-ray photons, in particular photons (32,34) in a computer tomograph. Photons (32,34) are converted into an electrical pulse and compared against a threshold using a discriminator (20). The electrical network (12) performing these functions comprises a switching element (28), that can modify the electrical path (22) along which the process signals travel. The trigger signal (V T ) for actuating the switching element (28) is derived from an electrical state of the electrical path (22). If a pulse associated to a photon (32,34) is detected, the switching element (28) is actuated in order to avoid that the processing of the charge pulse stemming from a first photon (32) is affected by a subsequent second photon (34).

The fast counting stage (10) may for example comprise a fast counter (111) with a low bit-depth operating as a frequency divider in front of a slow counter (121) of high bit-depth in the slow counting stage (20). The counting circuitry (10, 20, 30) can optionally be fed via a multiplexer (4) with the signals of several (sub-)pixels (2). Furthermore, the pixels (1, 2) of the radiation device may optionally deliver energy resolved pulses.

摘要： Computed tomography (CT) systems are provided that utilize x-ray tube spectra in connection with the generation and/or interpretation of CT data. The disclosed systems and methods use x-ray tube spectra associated with CT systems to enhance contrast and/or image quality, e.g., by making use of energy selective detection techniques. The x-ray spectra may be determined in a variety of ways, e.g., incorporation of a spectral x-ray tube model into the CT system, using the output of Monte-Carlo simulations, and/or processing measured experimental spectral tube data for the CT system. The x-ray tube spectra is generally generated by and/or stored in a computer system associated with the CT system and may be used in support of an energy selective detective method and/or generation of spectral CT images.
