Abstract: The present invention provides a personalized registration method for a template library of anatomical morphology and mechanical properties of materials of bone CT images. In the method, a large number of bone CT images of healthy persons are used to build a statistical model capable of containing anatomical morphology and mechanical properties of materials of bones, the parameterized description of bones of a patient is realized by a personalized registration method for the statistical model and bone CT images, a prosthesis template library is built by using images of the patient and registration parameters, and the template library is matched with the CT images of the patient by the personalized registration method to retrieve template images and prosthesis models similar to the bone conditions of the patient from the template library as the initial reference template for design of personalized prosthesis implants.

Abstract: A pressing pump includes a pump case, a piston, a pump rod, and a pressing sleeve, where a pumping cavity is formed within the pump case; the piston is arranged within the pumping cavity and connected to the piston on an inner wall of the pumping cavity; a first end of the pump rod is connected to the piston; the pressing sleeve is sleeved on an outer circumference of a second end of the pump rod; a gap is formed between the pressing sleeve and the pump rod; and an inner circumference of the pressing sleeve and an outer circumference of the pump rod are clamped with each other to realize two-way motion limitation in a length direction of the pump rod. The pressing pump can maintain stable and smooth operation of the piston in the pressing process of the pressing pump.

Abstract: A method for preparing an image simulating the anatomy of a small subject test animal, and an apparatus for producing said image and an anatomical atlas for co-registering therewith, comprising the generation of two or more non-tomographic images of the test animals is described. Examples of the non-tomographic imaging modalities and the images generated include, but are not limited to one or more x-ray sources and resultant of x-ray projections, photographic cameras and resulting digital or optical images and surface scanners and resultant surface scans. The subject animal is positioned at a focal point in a carrier in an imaging enclosure. A combination of one or more of the non-tomographic images taken from different angles within the enclosure are combined and through an iterative process co-registered with the previously generated digital atlas of the anatomy of the same or similar test animals.
