Embodiments of the disclosed system and method provide for generating a multiple-energy X-ray pulse. A beam of electrons is generated with an electron gun and modulated prior to injection into an accelerating structure to achieve at least a first and second specified beam current amplitude over the course of respective beam current temporal profiles. A radio frequency field is applied to the accelerating structure with a specified RF field amplitude and a specified RF temporal profile. The first and second specified beam current amplitudes are injected serially, each after a specified delay, in such a manner as to achieve at least two distinct energies of electrons accelerated within the accelerating structure during a course of a single RF-pulse. The beam of electrons is accelerated by the radio frequency field within the accelerating structure to produce accelerated electrons which impinge upon a target for generating Bremsstrahlung X-rays.

An X-ray imaging apparatus is capable of cutting the time needed for the long-length image. A candidate point registration element 25 registers an end of a long-length region as a candidate point. A start location determination element 27 determines the candidate point closest to the present location of the imaging system as the imaging start location based on the distance between the present location of the imaging system and each candidate point. A distance that the imaging system shifts at the imaging preparation step of the X-ray images by determining the imaging start location prior to imaging of a series of X-ray images that form a long-length image can be shortened. When the long-length imaging is implemented multiple times, the shift-distance of the imaging system is further shortened by updating the setting of the imaging start location in advance every time when a series of X-ray images is taken, so that the time needed for the entire steps relative to the long-length imaging can be largely cut.

A radiographic system comprises: an irradiation control apparatus including a first timer configured to provide a time value for an irradiation timing; and a radiographic apparatus that is communicably connected to the irradiation control apparatus and includes a second timer configured to provide a time value for an imaging timing. The system measures a time difference between a time value of the first timer and a time value of the second timer; corrects at least one timer out of the first timer and the second timer so as to eliminate the time difference using one of a plurality of types of correction processing having different correction periods. The correction processing to be used is selected from the plurality of types of correction processing, based on an operating state of the radiographic apparatus.

Disclosed herein are a method for modifying a magnetic field using magnetic nanoparticles and an apparatus therefor. The method for modifying a magnetic field includes applying current to a single solenoid coil or to two parallel solenoid coils, measuring a strength of a magnetic field generated by the current at a preset target location using a measurement sensor, and controlling the strength of the magnetic field based on a concentration of a magnetic nanoparticle sample mounted in the single solenoid coil or the two solenoid coils so that the strength of the magnetic field matches a preset target value.

A composite image generation unit of a CPU of a console combines a camera image obtained by capturing an image of a subject located in an irradiation field using a camera and a positioning index image indicating a set position of the subject, which has been set in advance with respect to an in-image cassette position that is the position of the electronic cassette in the camera image, to generate a composite image. In a case in which the in-image cassette position is changed with the movement of the electronic cassette, the composite image generation unit changes a display position of the positioning index image with the change in the in-image cassette position.
