| 摘要 |
<p>The invention relates to a radiation detector, an arrangement and a method for an energy-dispersive detection of X-ray photons. X-ray photons are allowed to collide (701) in the radiation detector (201, 601), whereby there are produced (702, 703, 704, 705, 706, 707, 708) observations of the X-ray photons that collided in the detector. According to the invention, there are separately produced observations of X-ray photons (702, 703, 704) that collided in the first detector space (205, 501) of the radiation detector and X-ray photons (705, 706, 707, 708) that collided in the second detector space (206, 502) of the radiation detector. The (712) observations of X-ray photons that collided in the first detector space (205, 501) are ignored, when there is received a simultaneous observation of an X-ray photon that collided in the second detector space.
