Abstract
Disclosed are a method for converting radiographic image which comprises the steps of: PA1 (a) storing radiation energy-corresponding to a radiographic image in a stimulable phosphor of a panel comprising a stimulable phosphor-containing layer, PA1 (b) scanning the layer with a stimulating ray to release the stored energy as a fluorescence, and PA1 (c) detecting the fluorescence to form an image, wherein the stimulable phosphor is represented by the following formula: EQU (M.sub.1-x.M.sup.I.sub.x)X.aM.sup.II X'.sub.2.bM.sup.III X".sub.3 :dB wherein M represents either Cs or Rb; M.sup.I represents at least one of alkaline metals selected from the group consisting of Li, Na, K, Rb and Cs; M.sup.II represents at least one divalent meal selected from the group consisting of Be, Mg, Ca, Sr, Ba, Zn, Cd, Cu and Ni; M.sup.III represents at least one metal selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Cd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Al, Ga and In; B is an activator which is at least one metal selected from the group consisting of Eu, Tb, Ce, Tm, Dy, Pr, Ho, Nd, Yb, Er, Gd, Lu, Sm, Y, Tl, Na, Ag, Cu, Mg, Pb, Bi, Mn and In; X, X' and X" each may by the same or diffe…
