摘要:
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.

An image filing apparatus comprises an irreversible signal compression device for carrying out irreversible signal compression processing on an original image signal, which is made up of a series of image signal components representing an original image, and thereby generating an irreversibly compressed image signal. The irreversibly compressed image signal is stored on a first storage device. A difference operation device subtracts the image signal components of the original image signal and the irreversibly compressed image signal from each other which represent corresponding picture elements in the original image and the image represented by the irreversibly compressed image signal. A difference image signal is thereby generated which represents a difference image corresponding to the differences between the original image signal and the irreversibly compressed image signal. A reversible signal compression device carries out reversible signal compression processing on the difference image signal and thereby generates a reversibly compressed difference image signal. The reversibly compressed difference image signal is stored on a second storage device, on which information can be rewritten.

An artificial bone template selection system includes a template data storage system in which template data representing a plurality of templates representing a plurality of artificial bones of different shapes is stored. A bone shape measuring system measures the shape of bone to be supplemented by artificial bone on the basis of bone image data representing an image including the bone to be supplemented by artificial bone. A prospective template selection system selects at least one template the shape of which substantially conforms to the shape of the bone to be supplemented by artificial bone as measured by the bone shape measuring system out of the plurality of templates represented by the template data.

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:
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.

摘要:
A composite soft magnetic material having low magnetostriction and high magnetic flux density contains: pure iron-based composite soft magnetic powder particles that are subjected to an insulating treatment by a Mg-containing insulating film or a phosphate film; and Fe—Si alloy powder particles including 11%-16% by mass of Si. A ratio of an amount of the Fe—Si alloy powder particles to a total amount is in a range of 10%-60% by mass. A method for producing the composite soft magnetic material comprises the steps of: mixing a pure iron-based composite soft magnetic powder, and the Fe—Si alloy powder in such a manner that a ratio of the Fe—Si alloy powder to a total amount is in a range of 10%-60%; subjecting a resultant mixture to compression molding; and subjecting a resultant molded body to a baking treatment in a non-oxidizing atmosphere.
