Abstract

The present invention provides a flexible dual-energy detector module, and detectors and a detection device based on the same. The detector module includes: a first scintillator layer; a first flexible PD array which is attached to a surface of the first scintillator layer and includes a plurality of first flexible PD units arranged in an array, wherein the first flexible PD array and the first scintillator layer form a low energy detecting structure; a second scintillator layer which is located on one side of the low energy detecting structure; and a second flexible PD array which is attachedto a surface of the second scintillator layer and includes a plurality of second flexible PD units arranged in an array, wherein the second flexible PD array and the second scintillator layer form ahigh energy detecting structure. The second flexible PD array and the first flexible PD array are prepared based on the same flexible substrate. Through the above scheme, the high energy detecting structure and the low energy detecting structure are combined into one, and the design and connection of a reading circuit are simplified. Based on the flexible PD arrays, the alignment and adjustment ofeach PD module are simple, and each PD unit is enabled to absorb the almost equal amount of rays without modularizing the detector.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, and in particular relates to a flexible dual-energy detector module, a detector and detection equipment based thereon. Background technique [0002] X-ray radiation imaging utilizes the short-wavelength and easy-to-penetrate properties of X-rays, and the different characteristics of X-ray absorption by different substances, and imaging is performed by detecting the intensity of X-rays that pass through the object. A traditional dual-energy X-ray array detector consists of two detectors, one with high energy and one with low energy, wherein each detector includes a scintillator layer and a photodiode (PD) tube array. The low-energy detector near the X-ray source mainly absorbs low-energy X-rays, and the high-energy detector is located behind the low-energy detector and mainly absorbs the high-energy part of the X-ray energy spectrum. [0003] In the prior art, along the X-ray dire...
