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.

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.

In a radiation image processing apparatus, signal processing for determining the shape and location of an irradiation field, adjusting read-out conditions for a final readout from a preliminary read-out image signal, adjusting image processing conditions, and/or detecting an abnormal pattern is carried out on an image signal representing a radiation image by using a neural network. After the neural network, the learning operations of which have been carried out, is incorporated into the radiation image processing apparatus, modifying information is entered from an input device into the neural network. The modifying information is used to modify the signal processing carried out by the neural network and thereby to carry out re-learning operations of the neural network.

A method for adjusting conditions comprises the steps of, when a radiation image of a specific object is recorded and read out, investigating whether recording and read-out operations were or were not carried out in the past for the same object as the specific object. When recording and read-out operations were carried out in the past for the same object as the specific object, image recording conditions for the specific object are adjusted such that they coincide with those under which the recording operation was carried out for the same object as the specific object. Also, instead of read-out conditions for a final readout, which is to be carried out for the specific object, being adjusted on the basis of a preliminary read-out image signal representing the radiation image of the specific object, the read-out conditions for the final readout to be carried out for the specific object are adjusted such that they coincide with those under which the final readout was carried out from the radiation image of the same object as the specific object. Recording and read-out operations for the specific object are carried out under the conditions, which have thus been adjusted.
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.

In a small-scale medical facility, appropriate storage and management of medical images whose storage is mandatory for a predetermined period becomes easier. A storage terminal installed in a medical facility is connected to a mobile storage system, and image data stored in the storage terminal are transferred to the mobile storage system. The mobile storage system storing the image data is connected to an image data storage apparatus installed in an image storage center, and transmits the image data to the image data storage apparatus. The image data storage apparatus stores the image data and calculates the date of storage expiration of the image data. The image data storage apparatus stores the image data until the expiration date.

A portable radiation imaging system is provided which is capable of always performing imaging in a state where the tilt of the radiation emitted from a radiation source in relation to the detection surface of an image detection device is substantially perpendicular. The system is equipped with a tilt adjustment means that makes the tilt of the radiation in relation to the detection surface of a radiation image detection device substantially perpendicular by changing the tilt angle of a radiation source based on an angular signal representing the degree of tilt of the radiation in relation to said detection surface output by an angular signal output means, and a command means that generates an exposure command to the radiation source when the tilt of the radiation to be emitted from said radiation source in relation to the detection surface of said radiation image detection device is substantially perpendicular.

摘要:
A primary prospective abnormal shadow is detected in each of at least two radiation images of an object taken in different directions. Only primary prospective abnormal shadows which are detected in the respective radiation images and are in substantially the same position on the object is taken as a final prospective abnormal shadow.
