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: A medical image processing device acquires a user operation. The medical image processing device specifies, from a three-dimensional medical image in which one or more organs appear, an organ of interest to which to apply information. The medical image processing device applies predetermined information to the organ of interest that has been specified. The medical image processing device controls a display device so as to display the three-dimensional medical image.

Abstract: Provided is an image processing device including a changing unit that changes a threshold value of intensity of each of points within an image, a first display control unit that controls displaying of points including an intensity value equal to or greater than the threshold value every time the threshold value is changed by the changing unit, a receiving unit that receives designation of one or a plurality of predetermined regions within a displayed image based on an operation of a user, a fixing unit that fixes the threshold value of each of the points within the designated predetermined region as a threshold value by the changing unit at a time of designation of the predetermined region, a second display control unit that controls displaying of points including an intensity value equal to or greater than the threshold value fixed by the fixing unit among the points within the predetermined region, and points including an intensity value equal to or greater than the threshold value to be changed by the chan
