摘要： The objective thereof is to obtain a multi-leaf collimator and a particle beam therapy system in which a high-contrast irradiation field can be formed without undergoing the effect of a penumbra. There are provided a leaf row (5 C ) in which a plurality of leaf plates (5 L ) are arranged in the thickness direction of the row (5 C ) in such a way that the respective one end faces (E L ) of the leaf plates (5 L ) are trued up and a leaf plate drive mechanism (5 D ) that drives each of the plurality of leaf plates (5 L ) in such a way that the one end face (E L ) approaches or departs from a beam axis (X B ). In each of the leaf plates (5 L ), a facing side (PL) facing a leaf plate that is adjacent to that leaf plate in the thickness direction is formed of a plane (P sa ) including a first axis (A sa ) on the beam axis (X B ); the leaf plate drive mechanism (5 D ) drives the leaf plate (5 L ) along a circumferential orbit (O L ) around the second axis (A sb ), on the beam axis (X B ), that is perpendicular to the beam axis (X B ) and the first axis (A sa ).

摘要： The invention relates to a method for capturing a three-dimensional x-ray image (1) of an object (2) by means of an x-ray system (3) comprising an x-ray source (4), an x-ray detector (5) and a shutter matrix (7), the shutter matrix (7) having a plurality of shutter elements (18), the x-ray absorption properties of which are controllable. In the first method step, at least one region (21) to be captured of the object (2) is defined, wherein settings are planned for the individual shutter elements (18) of the shutter matrix (7) for different rotary positions (14, 15, 16, 17), taking into account the defined region (21) to be captured. Then, a plurality of two-dimensional x-ray images is captured from the planned rotary positions (14, 15, 16, 17) during at least one partial rotation (9) using the planned settings of the shutter elements (18), wherein the overall three-dimensional x-ray image (1) of the region (21) to be captured is generated from the individual two-dimensional x-ray images.

摘要： In a collimator 6 according to the present invention, an irradiation field F is accurately set with respect to an affected area T by making a plurality of leaf plates 13B be slidable along a left-right direction X. Further, by making separate leaf plates 15 of the leaf plates 13B be slidable in an irradiation direction Y as well, it is possible to bring the separate leaf plates 15 close to the body surface of a patient P so as to conform to the outer shape of an irradiation site. A gap between the collimator 6 and the patient P is narrowed thereby, whereby dispersion of neutrons is suppressed. As a result, a neutron dose which is irradiated to the affected area T per hour is secured, and thus irradiation time is shortened.

摘要： The present specification discloses a beam chopping apparatus, and more specifically, a helical shutter for an electron beam system that is employed in radiation-based scanning systems, and more specifically, a beam chopping apparatus that allows for variability in both velocity and beam spot size by modifying the physical characteristics or geometry of the beam chopper apparatus. The present specification also discloses a beam chopping apparatus which provides a vertically moving beam spot with substantially constant size and velocity to allow for substantially equal illumination of the target. In addition, the present specification is a beam chopping apparatus that is lightweight and does not cause an X-ray source assembly employing the beam chopper to become heavy and difficult to deploy.

摘要： X-ray or infrared imaging device, of the radiography or scanography type, comprising: a support (1) for receiving a body (3) to be examined; a source (5) supplying a focus (F, F1, F2), from which there emanates an X-ray or light beam (7,71,72) that passes through a slit (8) in a dose limiter (8, 8a, 8b) translationally controlled so as to scan the body (3) to be examined; a detector (9) translationally controlled so as to be irradiated or illuminated by the beam scanning the body (3) to be examined and to detect an attenuated intensity as a function of the X-rays or light rays passing through the body (3) to be examined; an analogue-to-digital converter (11), for converting the detected intensities into data for determining an attenuation by the body (3) to be examined of the X-rays or light rays; and a computer (13) programmed to process the data coming from the conversion of the detected intensities in order to result in an image expressing the attenuation of the X-rays or light rays by the examined body (3). According to the invention, the dose limiter (8, 8a, 8b) is translationally controlled with a speed proportional to that of the detector (9), said speed being controlled by the ratio (D2/D1) of the distance (D1) between the focus (F,F1,F2) and the detector (9) to the distance (D2) between the focus (F, F1, F2) and the dose limiter (8, 8a, 8b).
