摘要： Two radiation images of a single object, which comprises a soft tissue and a bone tissue, are formed respectively with two kinds of radiation having different energy distributions, the two radiation images being to be subjected to energy subtraction processing. The energy subtraction processing is carried out on the two radiation images, and a bone image, in which the pattern of the bone tissue in the object has been extracted or emphasized, is thereby formed. Numerical information concerning the density of the bone constituent is obtained in accordance with the bone image. A bone trabecula pattern emphasizing process is carried out on the bone image, and information representing the form of bone trabeculae is thereby obtained.

摘要： A method and apparatus for carrying out tomographic image processing that enables lung areas and a mediastinum in a chest tomographic image to be reproduced in one image with appropriate contrast is provided. Image data representing a chest tomographic image are obtained by using a tomography apparatus. Normalization means in a tomographic image processing apparatus normalizes the image data and obtains normalized image data. Compression processing means carries out dynamic range compression processing on the normalized image data to compress a high density range thereof. The image data after the compression processing are subjected to frequency enhancing processing, and the image data after the frequency enhancing processing are then subjected to tone conversion processing. The processed image data obtained in the above manner are reproduced by a reproduction apparatus.

摘要： An measurement processing apparatus for efficiently measuring geometric data of an image is provided. A reference-image outputting means forms a reference-image based on an image that has been previously measured as well as a setting order data which indicates a suggestion as to the order in which the measuring points should be set and which shows the same setting order in which the measuring points were set for a previously performed measurement of a past-measurement image, and outputs the reference-image and the setting order data to an image display means. While consulting the reference-image and the setting order data displayed on the image display means, an operator can set, by use of a measuring point setting means, the measuring points at the correct positions and in the correct order in the subject image displayed on a display screen, and the geometrical data can be measured automatically and efficiently.
