Provided is a system and method for semi-automatically processing a human body image. A segmentation unit segments portions having correlations with one another in a human body image using at least one of image processing functions. A feedback unit performs at least one of the image processing functions on the segmented human body image to improve accuracy of the segmented human body image. A classification unit applies corresponding colors to tissues of the segmented human body image, incorporates the segmented human body image into one image, and creates an image in which classification is completed. A display unit shows images that are results of processing by the segmentation unit, the feedback unit, and the classification unit on independent screen windows.

An antenna radiation pattern measurement device that measures a radiation pattern of an AUT by using a source antenna includes a control unit, an analysis unit, and a measurement unit. The control unit controls driving of the source antenna and the AUT. The analysis unit measures an electric field value from a radio frequency (RF) signal that is transmitted from one of the source antenna and the AUT and received by the other antenna. In addition, the measurement unit controls the control unit and the analysis unit and measures a radiation pattern of the AUT by using the electric field value.

The present invention relates to a structure of an antenna and its shielding structure for a mobile phone which may significantly reduce the hazardous electromagnetic wave transmitted to the user's body. The present invention arranges a monopole antenna inside of the mobile phone housing, and installs an electromagnetic wave absorber between the antenna and the circuit board. The electromagnetic wave absorber can absorb the electromagnetic wave reflected form conductive plate constituting the circuit board. Thus, the adverse effect of the reflected electromagnetic wave to the performance of antenna is prevented and the amount of the electromagnetic wave to which the users is exposed can be significantly reduced as well.
