PURPOSE:To rapidly obtain a subtraction image corrected in strain, by storing a corrected image obtained by applying strain correction to the image immediately after the body movement of an examinee is generated by a strain correction means in a memory device and performing subtraction between the stored corrected image and one image read from the memory device using an operator. CONSTITUTION:For example, strain correction is applied to the image (L2) immediately after the movement of an examinee 10 is generated to obtain a corrected image (M') which is, in turn, stored in a memory device 5 and subtraction is performed between said stored corrected image (M') and one image (L1, L2,...) read from the memory device 5 using an operator 7 and the obtained subtraction image (S1'', S2'',...) can be displayed on an image display apparatus 8. Therefore, the subtraction image S(S1'', S2'',...) corrected in strain is rapidly obtained within a shortened processing time only by performing subtraction using the operator 7 without correcting strain every time by the strain correction means 6. From this, a plurality of the subtraction images different in the advance time phase of a contract agent can be rapidly displayed. |
