Imaging control system and imaging control method

An imaging control system comprising:

• an X-ray imaging device to rotate together with a rotating gantry around a patient, to radiate X-rays to the patient for taking multiple two-dimensional X-ray images, and to output image data including the multiple two-dimensional X-ray images;
• a respiratory monitor to watch respiratory motion of the patient and to output respiratory data indicating the respiratory motion;
• a control calculating device to acquire the image data from the X-ray imaging device and to acquire the respiratory data from the respiratory monitor;
• the control calculating device comprising:
• a respiratory waveform divider to slice at least one of cycle and amplitude in a respiratory waveform of the respiratory motion included in the respiratory data into multiple specific fragments,
• an image data sorter to acquire a rotational angle indicating a rotational position of the rotating gantry from a gantry controller for controlling a rotation of the rotating gantry, and to sort the multiple two-dimensional X-ray images contained in the image data by each of the multiple specific fragments into the multiple two-dimensional X-ray images, and
• a three-dimensional reconstructor to reconstruct the multiple two-dimensional X-ray images categorized by each of the multiple specific fragments based on the rotational angle of the rotating gantry at shooting to generate multiple three-dimensional reconstructed images, wherein the control calculating device is configured to determine whether the image data is appropriate for generating the multiple three-dimensional reconstructed images, and to discard at least a portion of the image data that is determined to be inappropriate;
• and
• the control calculating device determines that, for the multiple two-dimensional X-ray images acquired during one rotation of the rotating gantry and categorized in each predetermined fragment of amplitude in the respiratory waveform, the image data is inappropriate for generating the multiple three-dimensional reconstructed images in a case of uneven numbers of the multiple two-dimensional X-ray images among each predetermined fragment of amplitude in the respiratory waveform, and discards all the image data at that time without generation of the multiple three-dimensional reconstructed images.
