摘要： A radiotherapy system has: a placing unit placing a subject; an imaging unit performing an imaging of the subject; a region setting unit setting a required region of first image data obtained by the imaging unit performing the imaging of the subject and setting a corresponding required region of second image data obtained by, before the imaging, performing a pre-imaging of the subject; a histogram generating unit generating a dose-volume histogram of the required region of the first image data and generating a dose-volume histogram of the required region of the second image data; a difference computing unit computing a difference between the dose-volume histogram of the required region of the first image data and the dose-volume histogram of the required region of the second image data; and an outputting unit, if it is determined that the difference is greater than a threshold value, outputting the determination to an outside.

摘要： A radiographic image diagnosis apparatus includes a photographing unit having a radiation source and a 2D radiation detector to generate data of a fluoroscopic image of an object to be examined. Volume data is generated on the basis of the data of plurality of fluoroscopic images of the object at different angles which are acquired by the photographing unit. A measuring mechanism measures the position and angle of the photographing unit with respect to the object. Projection image data is generated from the volume data on the basis of the position and angle of the photographing unit which are measured by the measuring mechanism. The volume data is then displayed. This makes it possible to display the projection image with substantially the same position and direction as those of a fluoroscopic image.
