便携式X光机主要分为一体机和分体机两类；一体机机长通常在50-70CM，机器设有手提设计，工作时置于平面上，机器两端分别为发射与接受X射线，经过处理后由机器一段自带的影像增强器观测。对于部分高档数字便携式X光机通常可以进行AV视频输出或USB输出连接电脑处理或连接打印机打印。此类一体机不使用时可使用专用手提箱存放携带；另一类分体机多用于工业检测行业(工业检测X光机)，将机器置于水平面左右两端或专用工作台上下对其中产品进行检测，体积相对于一体机要略大些。
Portable X-ray machines are mainly divided into two types: one-piece machine and split machine; the captain of one-piece machine is usually 50-70CM, the machine has a portable design, working on the plane, the two ends of the machine are respectively emitting and receiving X-rays, after processing by a section of the machine with its own image intensifier observation. For some high-end digital portable X-ray machine can usually be AV video output or USB output connected to computer processing or connected to printer printing. This kind of integrated machine can be stored and carried in special suitcases when not in use; another kind of split machine is mostly used in the industrial testing industry (industrial testing X-ray machine), the machine is placed on the left and right sides of the horizontal plane or under the dedicated workbench to test one of the products, the volume is slightly larger than the integrated machine.
