RADIOLOGICAL IMAGE CONVERSION PANEL, METHOD OF MANUFACTURING THE SAME, AND RADIOLOGICAL IMAGE DETECTION APPARATUS
First Claim
1. A radiological image detection apparatus comprising:
- a radiological image conversion panel comprising a phosphor containing a fluorescent material that emits fluorescence by radiation exposure; and
a sensor panel which detects fluorescence generated from the radiological image conversion panel and converts the fluorescence into an electrical signal,wherein the phosphor comprises a columnar section formed by a group of columnar crystals which are obtained through columnar growth of crystals of a fluorescent material, and a non-columnar section,the columnar section and the non-columnar section are integrally formed on the sensor panel to overlap in a crystal growth direction of the columnar crystals so that the sensor panel, the non-columnar section and the columnar section are provided in this order,a thickness of the non-columnar section along the crystal growth direction is non-uniform in a region of at least a part of the non-columnar section,the sensor panel is supported by a substrate comprising plastic, anda surface of the sensor panel is flattened by a resin material comprising polyimide or parylene.
