PURPOSE:To accurately and simply estimate a stomach region by setting a two-dimensional model from an X-ray standing position full-image and using position data obtained by operation applying the external force applied to the stomach at the time of imaging in a reverse direction as estimation data. CONSTITUTION:An X-ray standing position front full-image is inputted using an image reader to be stored in a memory apparatus and, from this image data, a contour dot row is extracted using density data and reference data to calculate the characteristic points on a contour. Next, representative points are determined at an interval of 50 points from the contour dot row of the stomach so as to contain the characteristic points to form a cross-sectional two-dimensional model. Then, the two-dimensional model is deformed by operational processing using the representative points and the values of Ka, Kb, Ec, gamma preliminarily inputted from a keyboard. At last, when the obtained deformation result of the two-dimensional model is outputted to paper using a printer or outputted to a display apparatus, the shape of a stomach region due to a stomach, X-ray double contrast image shown by a curve (f) is obtained. |
