Abstract: An operation image positioning method is disclosed. A point-cloud camera captures a point-cloud image of first and second positioning marks respectively fixed on a treated portion and an X-ray imaging machine. The first and second positioning marks within the point-cloud image are recognized to compute a first conversion module between the point-cloud camera and the treated portion and a second conversion module between the point-cloud camera and the X-ray imaging machine, thereby computing a third conversion module between the treated portion and the X-ray imaging machine. An image positioning camera captures a positioning image of the first positioning mark. The first positioning mark within the positioning image is recognized to compute a fourth conversion module between the image positioning camera and the treated portion. A fifth conversion module between the image positioning camera and the X-ray imaging machine is computed according to the third and fourth conversion modules.

Abstract: An auxiliary screening system and an auxiliary screening method for a hip joint of a baby are provided. The auxiliary screening method includes: collecting plural images of the hip joint; performing an image analysis operation on each of the images of the hip joint to extract plural image features of each of the images of the hip joint and determining whether each of the images of the hip joint is a standard image according to the image features of each of the images of the hip joint; and when at least one of the images of the hip joint is determined as the standard image, plural angle parameters are calculated and the at least one of the images of the hip joint that is determined as the standard image is outputted, in which the angle parameters include values of an angle ? and an angle ?.

Abstract: A system for register operating space includes a first positioning mark, a local camera, a second positioning mark, a global camera and a computer system. The first positioning mark is set on a patient. The local camera captures a first image covering the first positioning mark. The second positioning mark is disposed on the local camera. The global camera captures a second image covering the second positioning mark. The focal length of the global camera is shorter than the focal length of the local camera. The computer system is communicatively connected to the local camera and the global camera to provide a navigation interface based on the first image and the second image.

Abstract: A system for registering operating space includes a back bracing, a computer system and a robotic arm. The back bracing includes positioning marks which can be imaged in a computer tomography (CT) image, and the back bracing is used to be worn by a patient. The computer system computes image coordinates of the positioning marks in an image space. A base of the robotic arm is connected to the back bracing in an operating space after the CT image is generated. The robotic arm contacts the positioning marks in the operating space and meanwhile the computer system obtains arm coordinates of the robotic arm in an arm space. The computer system generates conversion models among the image space, the operating space, and the robot arm space according to the image coordinates and the arm coordinates.

Abstract: A system for registering operating images includes an X-ray imaging machine, a visible-light camera, a rectifier and a computer system. The X-ray imaging machine captures a first X-ray image of the rectifier, and the visible-light camera captures a first visible-light image of the rectifier at the same time. The computer system recognizes the rectifier in the first X-ray image and in the first visible-light image to compute a conversion model between a coordinate system of the X-ray imager and a coordinate system of the visible-light camera. The X-ray imaging machine also captures a second X-ray image of a patient on which a positioning marker is set, and the visible-light camera captures a second visible-light image of the positioning marker. The computer system provides a navigation interface by combining the second X-ray image and the second visible-light image based on the conversion model.
