Abstract: Among other things, one or more techniques and/or systems for generating a three-dimensional combined image is provided. A three-dimensional test image of a test item is combined with a three-dimensional article image of an article that is undergoing a radiation examination to generate the three-dimensional combined image. A first selection region of the three-dimensional article image is selected. The three-dimensional test image of the test item is inserted within the first selection region. Although the test item is not actually comprised within the article under examination, the three-dimensional combined image is intended to cause the test item to appear to be comprised within the article.

Abstract: A method includes generating a real-time ultrasound image of anatomy of interest. At least a sub-portion of the anatomy of interest is deformed from an initial location to a different location by pressure applied by an external force. The method further includes obtaining a 2-D slice, which corresponds to a same plane as the real-time ultrasound image, from 3-D reference image data, wherein a corresponding sub-portion is at the initial location. The method further includes determining displacement fields for the sub-portion from the sub-portion, the corresponding sub-portion and other anatomy not-deformed in the real-time ultrasound image and the 3-D reference image data. The method further includes deforming the 3-D reference image data using the displacement fields, which creates deformed 3-D reference image data based on the different location.

Abstract: The overload protection device used on a high-speed dental handpiece includes a valve body, a piston, an elastic member, and a valve plug. The valve body is provided with an air chamber and an air intake passage in communication with each other. The piston is arranged in the air chamber. The valve plug is arranged at an end of the air chamber away from the air intake passage and is connected with the valve body. The elastic member is arranged between the piston and the valve plug. An outer surface of the valve body is provided with a plurality of air discharging holes which is in communication with the air chamber. The piston is capable of opening or closing the air discharging holes when moving vertically within the air chamber. The present invention further discloses a high-speed dental handpiece with an overload protection device.
