PURPOSE:To provide the image reconstituting method which can obtain an image of a good quality by improving the interpolation accuracy at the time of reconstitution in the case a helical scan is used, and also, adjusting arbitrarily thickness of a slice. CONSTITUTION:By using a two-dimensional (surface) detector, data are collected at equal intervals in a slice position and its vicinity, or the data of an equal interval are utilized from among the data taken out in sufficient density, and from this obtained data of an equal interval, data in a slice position is interpolated by using a sampling function, and by using the data obtained by this interpolation, the image is reconstituted. |
