Description
技术领域Technical Field

背景技术Background technique
X射线源和X射线成像技术经历了百多年的发展，已经在各行各业广泛应用，极大地推动了科学技术和社会的发展。X-ray sources and X-ray imaging technology have experienced more than a hundred years of development and have been widely used in all walks of life, greatly promoting the development of science and technology and society.
20世纪70年代出现的CT技术将X射线成像技术带入更高更快的发展阶段，滑环CT成为一个时代的经典。但是，滑环CT诞生之初，就有科学家认识到其旋转运动模式固有的扫描速度限制和在运动器官成像上时间分辨率的局限，滑环CT经历五十年的发展，其扫描速度和时间分辨率已接近天花板，难以再提升。The emergence of CT technology in the 1970s brought X-ray imaging technology to a higher and faster development stage, and slip ring CT became a classic of the era. However, at the beginning of the birth of slip ring CT, scientists realized the inherent scanning speed limitation of its rotational motion mode and the limitation of time resolution in imaging moving organs. After fifty years of development, the scanning speed and time resolution of slip ring CT have reached the ceiling and are difficult to improve.
目前使用的CT成像技术，想要获取扫描对象的立体空间信息时，需要通过移动X射线源来实现对扫描对象一定范围内的不同角度X射线透视信息获取，操作较为繁琐。When currently used CT imaging technology wants to obtain three-dimensional spatial information of the scanned object, it is necessary to move the X-ray source to obtain X-ray perspective information at different angles within a certain range of the scanned object, which is a relatively cumbersome operation.

具体实施方式Detailed ways
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述；显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例，基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
如图1-2所示，本申请实施例公开一种弧形分布式X射线检测装置，包括输送带10、X射线源、探测器30以及控制系统。输送带10用于输送待扫描对象，将待扫描对象输送到探测器30上方进行X射线检测。设置时，输送带10两侧对应设置有支撑板11，两块支撑板11上端设置有跨设在输送带10上方的壳体12。X射线源布置在壳体12内，用于向待扫描对象发射X射线。探测器30设置在输送带10下方并对应X射线源布置，探测器30用于接收X射线源所发射的X射线并将信号穿出给控制系统。As shown in FIGS. 1-2 , the embodiment of the present application discloses an arc-shaped distributed X-ray detection device, including a conveyor belt 10, an X-ray source, a detector 30, and a control system. The conveyor belt 10 is used to convey the object to be scanned, and the object to be scanned is conveyed to the top of the detector 30 for X-ray detection. When set up, support plates 11 are correspondingly arranged on both sides of the conveyor belt 10, and a shell 12 is arranged on the upper ends of the two support plates 11 and straddles the conveyor belt 10. The X-ray source is arranged in the shell 12, and is used to emit X-rays to the object to be scanned. The detector 30 is arranged below the conveyor belt 10 and corresponds to the arrangement of the X-ray source. The detector 30 is used to receive the X-rays emitted by the X-ray source and transmit the signal to the control system.
X射线源包括若干X射线管20，X射线管20可以是几个也可以是几十个上百个，具体根据应用场景来布置。X射线管20布置在壳体12内，具体布置时，X射线管20主要呈弧形间隔分布，每个X射线管20的布置角度均不同，但每个X射线管20的X射线照射角度均指向探测器30。优选的方案是，若干X射线管20从壳体12的位于输送带10长度方向的中轴线向两侧对称分布，自中间向两侧高度逐渐降低，形成弧形布置，可以是四分之一圆弧，也可以是半圆弧或者四分之三圆弧。每个所述X射线管20对应设置有一个阴极控制设备，阴极控制设备与控制系统连接，控制系统通过阴极控制设备可独立控制每一个X射线管20，使得每一个X射线管20可以担负发射X射线、根据需求按顺序开启，有效延长了X射线管20的使用寿命。The X-ray source includes several X-ray tubes 20, which can be several or dozens or hundreds, and are arranged according to the application scenario. The X-ray tubes 20 are arranged in the housing 12. When arranged specifically, the X-ray tubes 20 are mainly distributed in an arc shape, and the arrangement angles of each X-ray tube 20 are different, but the X-ray irradiation angle of each X-ray tube 20 is directed to the detector 30. The preferred solution is that the several X-ray tubes 20 are symmetrically distributed from the central axis of the housing 12 in the length direction of the conveyor belt 10 to both sides, and the height gradually decreases from the middle to both sides to form an arc arrangement, which can be a quarter arc, a semicircular arc or a three-quarter arc. Each of the X-ray tubes 20 is correspondingly provided with a cathode control device, which is connected to the control system. The control system can independently control each X-ray tube 20 through the cathode control device, so that each X-ray tube 20 can be responsible for emitting X-rays and turned on in sequence according to demand, effectively extending the service life of the X-ray tube 20.
本实施例中设置8个X射线管20，从壳体12的位于输送带10长度方向的中轴线向两侧对称分布，每侧分布有4个，且中间向两侧高度逐渐降低，8个X射线管20的连线形成一条弧线。这样使得两边的X射线均匀分布，可以使得X射线具有更广的照设角度。在实际使用时，X射线管20采用碳纳米X射线管20，碳纳米X射线管20具有光子效率高、低功耗、可控发射、易于集成等多种优势。安装时，8个X射线管20通过8个阴极控制设备独立控制，互不干扰，这样就不会因某一X射线管20的损坏或者故障导致整个机器无法使用。在控制时，可以每个X射线管20单独发射X射线，也可以操控多个X射线管20同时或者顺序间隔发射X射线，使得X射线发射可控，功耗较小。In this embodiment, eight X-ray tubes 20 are arranged, which are symmetrically distributed from the central axis of the housing 12 in the length direction of the conveyor belt 10 to both sides, with four on each side, and the height gradually decreases from the middle to both sides, and the connection line of the eight X-ray tubes 20 forms an arc. In this way, the X-rays on both sides are evenly distributed, which can make the X-rays have a wider irradiation angle. In actual use, the X-ray tube 20 adopts a carbon nano X-ray tube 20, which has many advantages such as high photon efficiency, low power consumption, controllable emission, and easy integration. During installation, the eight X-ray tubes 20 are independently controlled by eight cathode control devices without interfering with each other, so that the entire machine will not be unusable due to damage or failure of a certain X-ray tube 20. During control, each X-ray tube 20 can emit X-rays separately, or multiple X-ray tubes 20 can be controlled to emit X-rays simultaneously or sequentially, so that the X-ray emission is controllable and the power consumption is small.
进一步的，上述X射线源的检测方法包括以下步骤：Furthermore, the above-mentioned X-ray source detection method comprises the following steps:
步骤1：扫描对象通过输送带10输送到探测器30上方；Step 1: The scanned object is conveyed to the top of the detector 30 via the conveyor belt 10;
步骤2：控制系统控制若干X射线管20间隔启动，从不同角度对扫描对象进行快速扫描；Step 2: The control system controls a plurality of X-ray tubes 20 to start at intervals to quickly scan the scan object from different angles;
步骤3：探测器30接收X射线信号并传输到控制系统进行三维成像。Step 3: The detector 30 receives the X-ray signal and transmits it to the control system for three-dimensional imaging.
通过上述步骤，由于X射线源在不同的位置产生X射线，并通过控制系统设置控制程序控制阴极控制设备启闭X射线管20，这样就可以快速电控切换X射线出束的焦点位置形成相对扫描对象的不同角度的快速扫描，无需移动X射线源的位置，即可实现对扫描对象一定范围内的不同角度的X射线透视信息获取，并产生扫描对象的立体空间信息，从而提供了一种全新的快速三维X射线成像模式，可广泛应用于静态层析扫描成像等领域。Through the above steps, since the X-ray source generates X-rays at different positions, and the control program is set by the control system to control the cathode control device to open and close the X-ray tube 20, the focus position of the X-ray beam can be quickly switched electrically to form a fast scan at different angles relative to the scanned object. Without moving the position of the X-ray source, it is possible to obtain X-ray perspective information at different angles within a certain range of the scanned object and generate three-dimensional spatial information of the scanned object, thereby providing a new fast three-dimensional X-ray imaging mode that can be widely used in fields such as static tomography scanning imaging.
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
