Abstract: A tumor positioning method and device, and a radiotherapy system. According to the method, image registration can be performed on a projection image of a tumor and a first standard image so as to obtain a first offset, and a second standard image is generated according to the first offset. When a second offset satisfies a virtual re-sampling condition, the second standard image is updated according to the second offset, image registration is performed again until the second offset does not satisfy the virtual re-sampling condition, and an accumulated offset is then output. Since an executing body which updates the second standard image and performs the image registration is an image guide system, the method can therefore implement accurate positioning of a tumor without repeatedly moving a patient support device and repeatedly collecting projection images. The tumor positioning method has higher flexibility and efficiency, and can also prolong the service life of expensive devices such as patient support devices and image collection components.

Title: Pneumatically-actuated-muscle articulated plush toy
Inventor: LU XIAOPING
IPC: G09B23/36
Filed: 2019-10-10
Abstract: A battery-powered children's plush toy utilising lightweight pneumatically-actuated muscles to articulate parts of said toy. These pneumatic muscles are actuated by a pneumatic pump that may be located in a central location within the toy's plush stuffing and connected to said pneumatic muscles throughout the toy, with the means of pneumatic tubing. Said pneumatic tubing is thin and flexible, allowing for the sections of plush toy it travels through to be unaffected by actuation at its periphery and remain manually articulatable. The implementation of these components allows for plush toys to be robotically articulated in ways unfeasible when using traditional robotic toy actuators. Additionally, this invention retains the soft, compliant properties of a standard plush toy resulting in a product that is safer than traditional motorised mechanical toys which often comprise a hard-plastic shell under a thin textile layer.
