The target medical image can be any medical image, and the target medical image can be a medical image to be loaded. Exemplarily, the target medical image can be a CT image, a magnetic resonance (English: Magnetic Resonance, MR) image; It is an exemplary illustration, and does not mean that the present application is limited to this. Loading the target medical image may be a process of reading the target medical image into the cache/memory of the medical image loading device. Therefore, after loading the target medical image, the target medical image occupies a certain storage space in the cache/memory. It can be understood that the target medical image is stored in the cache/memory, and the loading of the target medical image can include a stored procedure. Exemplarily, the target medical image may be acquired from a radiation therapy planning system (English: Treatment Planning System, TPS) server, and the target medical image is loaded into the memory/cache.
