Section: claims

1. An X-ray image detecting apparatus comprising: an X-ray grid arranged to remove X-rays scattered by a subject;  a conversion member for converting X-rays passed by said X-ray grid into light having a predetermined wavelength; and  a plurality of photoelectric conversion elements arranged to receive light from said conversion member,  wherein said plurality of photoelectric conversion elements are arranged two-dimensionally spaced apart from each other and have predetermined insensitive regions disposed between said photoelectric conversion elements, said X-ray grid comprises a plurality of X-ray absorption members for removing scattered X-rays, each of said X-ray absorption members being arranged substantially only on said insensitive regions when viewed from a direction from which x-rays are incident, and said conversion member is arranged only in regions between said X-ray absorption members that are substantially adjacent to each other when viewed from the direction from which X-rays are incident. 2. The apparatus according to  claim 1 , wherein said conversion member is partitioned by said X-ray absorption members. claim 1 3. The apparatus according to  claim 1 , wherein said conversion member is partitioned by predetermined members which are different from said X-ray absorption members and located adjacent to each other. claim 1 4. The apparatus according to  claim 3 , wherein said predetermined members have a property of substantially not transmitting the light from said conversion member. claim 3 5. The apparatus according to  claim 1 , wherein said conversion member is partitioned by cavities, and wherein the surface of said conversion member facing said cavities has a property of substantially not transmitting the light from said X-ray conversion member. claim 1 6. The apparatus according to any one of claims  1  or  2  to  5 , wherein when viewed from a direction from which X-rays are incident, said X-ray absorption members are arranged in a stripe pattern and said conversion member is divided into parts, in a direction along said X-ray absorption members, in correspondence to respective ones of said photoelectric conversion elements. 7. The apparatus according to any one of claims  1  or  2  to  5 , wherein said X-ray grid is a converging grid having a predetermined focal point. 8. The apparatus according to any one of claims  1  or  2  to  5 , wherein said X-ray grid comprises intermediate substances disposed between said X-ray absorption members. 9. The apparatus according to  claim 1 , further comprising: claim 1 a first member, for supporting one end of each of said X-ray absorption members on one surface of said first member as well as holding said conversion member on another surface of said first member; and  a second member, for holding another end of each of said X-ray absorption members. 10. The apparatus according to  claim 9 , wherein said first member separates and holds said conversion member so that said conversion member is disposed substantially only in regions between said X-ray absorption members that are adjacent to each other when viewed from a direction from which X-rays are incident. claim 9 11. The apparatus according to  claim 10 , wherein said first member has a property of substantially not transmitting the light from said conversion member. claim 10 12. The apparatus according to  claim 1 , wherein said photoelectric conversion elements are arranged on an insulation substrate. claim 1 13. The apparatus according to  claim 1 , wherein said X-ray absorption members are arranged in a matrix or in a stripe pattern when viewed from a direction from which X-rays are incident. claim 1 14. The apparatus according to  claim 1 , wherein said X-ray absorption members have a property of reflecting the light from said conversion member. claim 1 15. The apparatus according to  claim 1 , wherein said X-ray grid has a grid ratio of at least 3:1. claim 1 16. An X-ray image acquisition apparatus comprising: an X-ray generator; and  an X-ray image detector,  wherein said X-ray image detector comprises:  an X-ray grid arranged to remove X-rays scattered by a subject;  a conversion member for converting X-rays passed by said X-ray grid into light having a predetermined wavelength; and  a plurality of photoelectric conversion elements arranged to receive light produced by said conversion member,  wherein said plurality of photoelectric conversion elements are arranged two-dimensionally with a predetermined insensitive region between each adjacent two of said photoelectric conversion elements, said X-ray grid comprising a plurality of X-ray absorption members for removing scattered X-rays, said X-ray absorption members are disposed substantially only on said insensitive regions when viewed from a direction from which X-rays are incident, and said conversion member is arranged only in regions between said X-ray absorption members that are substantially adjacent to each other when viewed from a direction from which X-rays are incident. 17. An X-ray image acquisition apparatus comprising: an X-ray image detector; and  an image processor that receives and processes image data obtained using said X-ray image detector,  wherein said X-ray image detector comprises:  an X-ray grid;  a conversion member for converting X-rays passed by said X-ray grid into light having a predetermined wavelength; and  a plurality of photoelectric conversion elements arranged to receive light produced by said conversion member,  wherein said plurality of photoelectric conversion elements are arranged two-dimensionally with a predetermined insensitive region between each adjacent two of said photoelectric conversion elements, said X-ray grid comprises a plurality of X-ray absorption members for removing scattered X-rays, said X-ray absorption members are disposed substantially only on said insensitive regions when viewed from a direction from which X-rays are incident, and said X-ray conversion member is arranged only in regions between said X-ray absorption members that are substantially adjacent to each other when viewed from a direction from which X-rays are incident.
