Section: claims

1. A detector arranged for detecting ionizing radiation, said detector comprising a Lu3Ga5O12:Nd fluorescent material, wherein the Nd3+ concentration is between ≧10 and ≦2000 wt. ppm, wherein the detector is an X-ray detector, CT-detector or Electronic Portal Imaging detector. 2. The detector according to claim 1, wherein the Lu3Ga5O12:Nd fluorescent material is a ceramic material. 3. The detector according to claim 1, wherein the Lu3Ga5O12:Nd fluorescent material includes: at least one of a Pr, Dy, Sm, Ce, Eu, or Yb contaminate, wherein a concentration of the at least one of the Pr, Dy, Sm, Ce, Eu, or Yb is less than 0.5 mole ppm. 4. A method, comprising:detecting ionizing radiation with a detector including a fluorescent material, wherein the a fluorescent material includes one of a Lu3Ga5O12:Nd fluorescent material, wherein the Nd3+ concentration is between ≧10 and ≦2000 wt. ppm. 5. The method of claim 4, wherein the fluorescent material is a ceramic material. 6. The method of claim 4, wherein the detector is an X-ray detector, CT-detector or Electronic Portal Imaging detector. 7. The method of claim 4, wherein the detector is part of a medical imaging system.
