20080262353 | METHOD AND APPARATUS FOR FAST VOLUME RENDERING OF 3D ULTRASOUND IMAGE - The invention provides a method and apparatus for fast volume rendering of 3D ultrasound image, comprising a dividing step, a calculating step, a determining step, a morphological closing operation step and a filling step, wherein each flat grid can be entirely filled by obtaining gray-scale values for all pixels inside the grid through interpolating; for the non-flat grid, the steps of dividing, calculating, determining and filling are performed repeatedly until the non-flat grid is subdivided into atomic grids to calculate gray-scale values for remaining pixels by projection. As the method can be finished in the rear end, no difficulty occurs in the implementation, and no process for being adapted to previous frames is required. Therefore, the method can improve the rendering speed effectively without degrading the quality of image to put 3D ultrasound imaging to the best use. | 10-23-2008 |
20080259543 | PIVOTABLE SUPPORT SHAFT FOR DISPLAY - A pivotable support shaft for connecting a display with a base member and supporting the display is disclosed. The support is designed to enable the display to have different postures in working condition and package and transporting condition. For example, in the working condition, the screen of the display may be pivotable between a pitch-up angle of about 20° and a pitch-down angle of about −20°, and in the package and transporting condition, the screen of the display may be pivoted down to a pitch-down angle of about −90° where the screen faces downwardly to reduce the package size and improve the transportation stability. | 10-23-2008 |
20080257350 | RESPIRATOR AND METHOD FOR CALIBRATING FLOW RATE MEASURING COMPONENT THEREOF - A respiration apparatus and a method for calibrating respiration parameters thereof are provided. A flow measuring reference component arranged behind the inspiratory valve in the ventilator is used as a flow measuring reference sensor for calibrating the flow sensor so that the flow rates of the gas through the flow measuring reference component and the flow sensor to be calibrated are identical or in a corresponding relation. Electrical parameters output from the flow sensor and the flow measuring reference component are respectively acquired and processed to obtain a relation curve of the gas flow rate and the electrical parameter of the flow sensor on the basis of the read gas flow rate and the electrical parameters of the flow sensor. The present invention enables automatic calibration for a flow sensor without using any measuring instrument. | 10-23-2008 |
20080253135 | DISPLAY WITH LIGHTING DEVICE - The present invention discloses a display with a lighting device comprising a display body having a housing and a power supply panel. The lighting device mounted at the bottom of the housing comprises a transparent base having a receiving cavity and a light source body disposed within the receiving cavity and powered by a power supply. Mounted at the bottom of the display body, the lighting device has the light downwards to illuminate the whole keyboard area of the medical diagnostic device such that the structure is tight without occupying extra space, thereby no inconvenience occurs during doctors' operation. Moreover, the entire lighting device is designed in a modularized manner, and therefore it is convenient for renewal and maintenance. | 10-16-2008 |
