Abstract:
1. An image processing apparatus for producing volume data based on projection image data of a specimen and producing sectional image data of the specimen based on the volume data, the image processing apparatus comprising: an acquisition unit acquiring the projection image data of the specimen; a receiving unit receiving from a user at least one of a position of the origin of a coordinate system of the volume data and an inclination of the coordinate system of the volume data, wherein the at least one of the position of the origin and the inclination of the coordinate system are directly input by the user, the volume data including a first plurality of coordinate parameters, wherein the receiving unit further receives trial adjustments to a movement amount and a rotational angle; a storing unit storing the trial adjustments as final adjustments when desired sectional image data are obtained; a setting unit setting: (i) first data including the at least one of the position of the origin of a coordinate system of the volume data and the inclination of the coordinate system of the volume data; and (ii) second data including the movement amount and the rotational angle associated with the final adjustments; a production unit producing the volume data based on the projection image data acquired by said acquisition unit in accordance with the first data and the second data, wherein said production unit includes: a readout unit reading out, from among voxels which compose the volume data produced by said production unit, those voxels which are positioned on a plane perpendicular to one of coordinate axes of the coordinate system of the volume data and regarding the read out voxels as pixels to produce the sectional image data.
