The PET detector may include: a crystal array including a plurality of crystal elements arranged in an array and light-splitting structures set on surfaces of the plurality of crystal elements, the light-splitting structures jointly define a light output surface of the crystal array; a semiconductor sensor array, which is set in opposite to the light output surface of the crystal array and is suitable to receive photons from the light output surface, the semiconductor sensor array comprises a plurality of semiconductor sensors arranged in an array.
Claims18
A positron emission tomography (PET) detector, the PET detector comprising:
- a crystal array, the crystal array including a plurality of crystal elements arranged in a single layer, wherein each of the plurality of crystal elements includes a first surface that gamma rays enter into, a second surface opposite to the first surface, and a side surface between the first surface and the second surface;
- and
- a semiconductor sensor array including a plurality of semiconductor sensors, the semiconductor sensor array being operably connected to a driver board, each of the plurality of semiconductor sensors having a light-receiving surface and a contact surface, the light-receiving surface being configured for receiving photons excited by the gamma rays from the second surfaces of the plurality of crystal elements, and the contact surface being opposite to the light-receiving surface that is in contact with the driver board directly;
- wherein the second surfaces of a first part of the plurality of crystal elements are in contact with the light-receiving surfaces of the plurality of semiconductor sensors directly or through an adhesive material, a second part of the plurality of crystal elements is not in contact with the plurality of semiconductor sensors, and the driver board completely covers the second surfaces of the plurality of crystal elements.
