Embodiment Construction
[0071] As described in the background art, when the existing technology obtains a large-scale image, it may cause the subject to receive excessive radiation dose. The inventor found that during the photography of large-scale images, after calculating the initial exposure frames for image stitching based on the pre-exposure area, if the initial exposure frames are not an integer, the doctor usually takes an integer greater than the initial exposure frames as The number of exposure frames in the actual photography process, therefore, causes the actual exposure area to be larger than the pre-exposure area, causing the subject to receive excessive radiation dose and causing certain damage to it.
[0072] The inventor considers that the calculated initial exposure frame number is adjusted accordingly to obtain the actual exposure frame number, so that the actual exposure area is not larger than the pre-exposure area, thereby reducing the radiation dose received by the subject during...
