Patent Images

1. An image processing apparatus comprising:

  • reconstruction means for detecting radiation rays emitted from an object in synchronization with an electrocardiogram of the object so as to reconstruct a first image of a myocardium at an end of diastole and a second image of the myocardium at an end of systole, the first and second images having first and second tomographic images of plural slices;

    means for developing the first and second tomographic images on a polar coordinate system;

    means for detecting an amount of shift in a rotational direction between the first and second tomograph images of each slice; and

    twist correction means for rotating at least either of the first and second tomographic images of each slice in accordance with the detected amount of the shift.
