A medical diagnostic device is characterized in that an image processing unit () includes an image noise removal part (') which removes the noise in the generated image of a person to be examined, a signal component enhancement processing part (&#x2032;) which generates an enhanced-signal component image by performing signal component enhancement processing of the image from which the noise is removed by the image noise removal part, and an image combining part (&#x2032;) which generates a combined image by combining the image of the person to be examined, the image from which the noise is removed by the image noise removal part, and an enhanced-signal component image subjected to signal component enhancement processing by the signal component enhancement processing part.

Medical diagnostic device and method of improving image quality of medical diagnostic device

The invention relates to a technique of improving a contrast of a lower-layer pattern in a multi layer by synthesizing detected signals from a plurality of detectors by using an appropriate allocation ratio in accordance with pattern arrangement. In a charged particle beam device capable of improving image quality by using detected images obtained from a plurality of detectors and in a method of improving the image quality, a method of generating one or more output images from detected images corresponding to respective outputs of the detectors that are arranged at different locations is controlled by using information of a pattern direction, an edge strength, or others calculated from a design data or the detected image. In this manner, a detection area of the detected signals can be expanded by using the plurality of detectors, and the image quality such as the contrast can be improved by synthesizing the detected signals by using the pattern direction or the edge strength calculated from the design data or the detected images.
