    • An ultrasound diagnosis system, a medical image display apparatus and displaying method that simultaneously acquires virtual endoscopy image data and multi-planar-reconstruction (MPR) image data of a diagnosing target region based on the volume data acquired from an object. Virtual endoscopy image data is generated by setting up a viewing point and a viewing direction on a volume data acquired from the object. A marker is provided on a target region of a lumen organ shown in the virtual endoscopy image data for setting up an observing direction. A reference line started from the volume data is set up along an observing direction. By comparing a voxel value of the volume data that is crossing to the reference line with a prescribed threshold value, a reference point where a surface of the diagnosing target region crosses the reference line is set up to the volume data. MPR image data is generated by extracting each voxel of the volume data corresponded to each of three MPR cross-sectional planes that are mutually orthogonally crossing at the reference point and displayed with the virtual endoscopy image data.

    • A nitrogen oxide purifying apparatus includes a gas absorption vessel (1) and a condenser (6), where the vessel receives an absorption solution containing liquefied N2O4 for absorbing NO and also receives a source gas to vary the temperature and/or pressure of the source gas and the absorption solution, while the condenser receives a gas from the gas absorption vessel (1) to vary the temperature and/or pressure of the gas. In the gas absorption vessel (1), the absorption solution containing liquefied N2O4 may be applied to the source gas containing NO, so that NO is absorbed in the absorption solution. Then the absorption-solution is heated and/or depressurized to generate an intermediate gas containing a relatively large amount of NO and a smaller amount of NO2 from the absorption solution. In the condenser (6), the intermediate gas is cooled and/or pressurized to give condensed N2O3 and/or condensed N2O4.
