This invention belongs to the field of medical signal processing technology, specifically a method and prediction system for constructing a three-dimensional tumor motion trajectory prediction model. It involves collecting temporal data of point clouds from the human chest and abdomen, as well as temporal location information of the tumor, and establishing a unified spatial coordinate system. The temporal data of the point clouds are divided into n time periods of total duration T1, and the temporal location information of the tumor is divided into n time periods of total duration T2, resulting in n training samples. The point clouds of the training samples are further divided into several pseudo-voxel sub-blocks according to the human projection plane, and K pseudo-voxel sub-blocks are selected based on motion saliency to obtain the temporal feature vector of the tumor motion. The temporal feature vector of the tumor three-dimensional motion trajectory prediction is used as input, and the corresponding tumor temporal location information is used as output to train an attention-enhanced dilated convolutional prediction network. This invention enables high-precision, non-invasive prediction of the three-dimensional tumor motion trajectory.

This invention provides a strong wind-resistant double-glass photovoltaic module structure, which includes multiple photovoltaic panels. Multiple connectors are slidably connected to the bottom of each photovoltaic panel, and adjacent photovoltaic panels are staggered together via these connectors. Each photovoltaic panel has a limiting component 1 and a limiting component 2 on both sides. When the photovoltaic panels are in the unfolded state, adjacent photovoltaic panels are fixed together by the limiting components 1 and 2, achieving rapid unfolding / storage and high space-efficiency folding. Through the sliding hinge block and groove design, adjacent photovoltaic panels can be folded around an axis or slid horizontally and stacked for storage. Combined with the detachable limiting components, users can quickly lock or release the panels without tools, achieving a seamless transition from the unfolded state to the compact folded state. This greatly improves the module's space storage efficiency, facilitates transportation and storage, and supports rapid deployment and dismantling.
