Abstract: An information processing system is provided. The information processing system comprises at least one processor configured to execute a program so that each following step is executed. In a reconstruction step, a first volume data is reconstructed, the first volume data indicating at least a part of the subject based on a plurality of first serial tomographic images of the subject. The first volume data includes first contour data representing an exterior of the subject and internal data including the inside of the subject. In a conversion step, the first volume data is converted to second volume data based on reference contour data other than the first contour data, the second volume data includes a second contour data different from the first contour data and the internal data including the inside of the body of the subject including the first contour data and the internal data including the inside of the body of the subject.
