X-ray image diagnostic system, image processing apparatus and image processing method

An image processing method performed in an image processing apparatus that reconstructs one frame of image data using block-level image data obtained by dividing the image data into a predetermined number of blocks and transmitting the image data, the method comprising:

• a reception step of receiving position information that is information indicating a position of the image data in a frame when the one frame of image data is reconstructed using the block-level image data, together with the block-level image data;
• a determination step of determining whether or not there was an error in transmission of the position information received in the reception step;
• a first storage step of storing the block-level image data corresponding to a position indicated in the position information determined not to have a transmission error in the determination step in a storage section in a first storage unit corresponding to the position information;
• a second storage step of storing, in a second storage unit, the block-level image data corresponding to the position information determined to have a transmission error in the determination step;
• an inference step of inferring position information for the block-level image data stored in the second storage unit based on a storage section in the first storage unit in which the block-level image data is not stored when the number of storage sections in the first storage unit in which the block-level image data is not stored matches the number of pieces of the block-level image data stored in the second storage unit;
• and
• a reconstruction step of reconstructing the image data of the frame using the block-level image data that has been stored in the first storage unit and the corresponding position information, the image data stored in the second storage unit, and the position information inferred in the inference step.
