Abstract:
The invention relates to a combined imaging detector ( 110 ) for the detection of x-ray and gamma quanta. The combined imaging detector ( 110 ) is adapted for simultaneous detection of gamma and x-ray quanta. The combined imaging detector ( 110 ) includes an x-ray anti-scatter grid ( 111 ), a layer of x-ray scintillator elements ( 112 ), a first photodetector array ( 113 ), a layer of gamma scintillator elements ( 114 ), and a second photodetector array ( 115 ) that are arranged in a stacked configuration along a radiation-receiving direction ( 116 ). The x-ray anti-scatter grid ( 111 ) comprises a plurality of septa ( 117 A, B, C ) that define a plurality of apertures ( 118 ) which are configured to collimate both x-ray quanta and gamma quanta received from the radiation receiving direction ( 116 ) such that received gamma quanta are collimated only by the x-ray anti-scatter grid ( 111 ). The use of the x-ray anti-scatter grid as a collimator for received gamma quanta results in a significantly lighter combined imaging detector.

Claim (Index 1):
Combined imaging detector for simultaneous detection of gamma and x-ray quanta, the combined imaging detector comprising:\n an x-ray anti-scatter grid; a layer of x-ray scintillator elements for generation of x-ray scintillation light signals in response to detected x-ray quanta; a first photodetector array configured to receive the x-ray scintillation light signals and to convert said x-ray scintillation light signals into a first group of electrical signals; a layer of gamma scintillator elements for generation of gamma scintillation light signals in response to detected gamma quanta; a second photodetector array configured to receive the gamma scintillation light signals and to convert said gamma scintillation light signals into a second group of electrical signals; wherein the x-ray anti-scatter grid, the layer of x-ray scintillator elements, the first photodetector array, the layer of gamma scintillator elements, and the second photodetector array are arranged in a stacked configuration along a radiation-receiving direction; wherein the x-ray anti-scatter grid comprises a plurality of septa that define a plurality of apertures which are configured to collimate both x-ray quanta and gamma quanta received from the radiation receiving direction such that received gamma quanta are collimated only by the x-ray anti-scatter grid; wherein the combined imaging detector further comprises a reconstruction unit configured to generate a reconstructed nuclear scintigraphy image from a measured nuclear scintigraphy image comprising a plurality of pixel values, the measured nuclear scintigraphy image being generated based on the second group of electrical signals; and wherein the reconstruction unit is further configured to generate the reconstructed nuclear scintigraphy image by subtracting a reference pixel value from the pixel values in the measured nuclear scintigraphy image.
