Abstract: Provided is an X-ray generator comprising an X-ray tube including a cylindrical body; an electron source in the body; a target at an end of the X-ray tube facing the electron source, the target generating X-rays by irradiation with electrons; a container in which the X-ray tube is arranged; insulating liquid filled between the X-ray tube and the container; and a holding member holding the body of the X-ray tube in the container, with a channel for the insulating liquid around the X-ray tube. The distance between the holding member and the end face at the end of the body in the direction in which the electron source and the target face is twice or more as large as the minimum width of the channel that is in contact with the outer surface of the X-ray tube at the end face side with respect to the holding member. This allows heat in the target to be quickly radiated, thus allowing X-rays to be generated stably for a long time.

Abstract: An illustrated example ionization device includes a pyroelectric electron accelerator that causes electrons to move away from the accelerator. A silicon target is positioned in a path of the electrons. X-ray radiation results from the electrons colliding with the target. In one example embodiment, the electrons moving between the accelerator and the target have energy up to 60 KeV and the target attenuates the energy so that the x-ray radiation has energy between 1 KeV and 3 KeV.

Abstract: Described here is a method for performing phase contrast imaging using an array of independently controllable x-ray sources. The array of x-ray sources can be controlled to produce a distinct spatial pattern of x-ray radiation and thus can be used to encode phase contrast signals without the need for a coded aperture. The lack of coded aperture increases the flexibility of the imaging method. For instance, because a fixed, coded aperture is not required, the angular resolution of the imaging technique can be increased as compared to coded-aperture imaging. Moreover, the lack of a radioopaque coded aperture increases the photon flux that reaches the subject, thereby increasing the attainable signal-to-noise ratio.

Abstract translation: 这里描述了使用独立可控x射线源的阵列进行相位对比成像的方法。 可以控制x射线源的阵列以产生X射线辐射的不同的空间图案，并且因此可用于对相位差信号进行编码，而不需要编码孔径。 编码孔径的缺乏增加了成像方法的灵活性。 例如，由于不需要固定的编码孔径，与编码孔径成像相比，可以增加成像技术的角度分辨率。 此外，缺乏无辐射光编码孔径增加了到达对象的光子通量，从而增加了可达到的信噪比。

Abstract: A transmission target of a vacuum container is operable to have a ground potential and an electro-optical system is floated at a positive potential in the vacuum container. An electron beam, which is converged by means of the electro-optical system, is decelerated immediately before the electron beam is incident to the transmission target. The electron beam has energy that is several times of the final set value until the electron beam passes through the electro-optical system, and a divergence action exerted by a spatial electric charge effect is reduced. Color aberration of the electro-optical system is proportional to energy of the electron beam. Thus, if the electron beam is decelerated after the electron beam has passed through the electro-optical system, aberration is reduced in proportion to the degree of deceleration, making it possible to concurrently reduce a focus size.

Abstract translation: 真空容器的透射目标可操作为具有接地电位，并且电光系统在真空容器中浮动为正电位。 通过电光学系统会聚的电子束在电子束入射到传输目标之前立即减速。 电子束的能量是最终设定值的几倍，直到电子束通过电光系统，并且由空间电荷效应产生的发散作用减小。 电光系统的色差与电子束的能量成比例。 因此，如果在电子束通过电光系统之后电子束减速，则与减速度成比例地减小像差，从而可以同时减小焦点尺寸。

Abstract: An improved particle beam treatment system optionally includes exchangeable particle beam nozzles. These particle beam nozzles may be automatically moved from a storage location to a particle beam path or between particle beam paths for use in medical applications. Movement may be achieved using a conveyance, gantry, rail system, or the like. The improved particle beam treatment system optionally also includes more than two alternative particle beam paths. These alternative particle beam paths may be directed to a patient from a variety of different angles and in different planes.
