Abstract: An information processing system is provided. The information processing system includes a controller. The controller is configured to execute each of the following steps. A reading step reads a plurality of sequential sectional images of an object. A setting step sets, based on a pixel value of a pixel in a predetermined area included in the sequential sectional images and preset reference information, material information representing a material of the object for the predetermined area, the reference information being information where a pixel value and a material are associated with each other. A reconstruction step reconstructs the plurality of sequential sectional images including the predetermined area for which the material information is set and thereby generating three-dimensional data on the object.

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.

Abstract: An information processing system comprises a control unit configured to execute each of the following steps. A reading step reads reference information on a reference maneuver that is a medical maneuver to be referred to by a user. The reference information includes a three-dimensional position of a track point in the reference maneuver. A first reception step receives a captured image of an external world as viewed by the user. A generation step generates, based on the three-dimensional position of the track point and the captured image, display information for presenting augmented reality regarding the reference maneuver to the user. The augmented reality three-dimensionally reproduces an aspect of a medical instrument used in the reference maneuver or a hand manipulating the medical instrument.
