Patent Number: 
Section: claims

1. An image processing apparatus that reconstructs block-level image data obtained by dividing the image data into a predetermined number of blocks and transmitting the image data, comprising:a reception unit configured to receive position information indicating a position of the block-level image data in the image data, together with the block-level image data;a determination unit configured to determine whether or not there is an error in the transmission of the position information received by said reception unit;a storage unit configured to store the block-level image data received by said reception unit; anda reconstruction unit configured to reconstruct the block-level image data stored in said storage unit if the number of transmission error(s) determined by said determination unit is one. 2. An X-ray image diagnostic system comprising:the image processing apparatus according to claim 1; andan imaging apparatus that transmits, to said image processing apparatus, image data captured by irradiating a subject with X-rays. 3. An image processing method performed in an image processing apparatus that reconstructs 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 indicating a position of the block-level image data in the image data, together with the block-level image data;a determination step of determining whether or not there is an error in transmission of the position information received in said reception step;a storage step of storing the block-level image data received in said reception step in a first storage unit; anda reconstruction step of reconstructing the block-level image data stored in the storage unit if the number of transmission error(s) determined in said determination step is one. 4. A non-transitory computer-readable storage medium storing, in executable form, a program for causing a computer to execute the image processing method according to claim 3.
