A detector using scintillating crystals is provided. The scintillating crystal is based on cerium doped lutetium yttrium orthosilicate (Ce:LYSO). With calcium (Ca) doped into Ce:LYSO, the electrovalence of Ce is further uniformly distributed. The scintillating crystal obtains high stability with 2 to 10 times greater electrical degree than that of a general scintillating crystal. Thus, radiative induction to cancer cells is improved and distribution of the cancer cells is easily figured out. |
