Problems solved by technology

In most cases, the high-precision DR / CT system equipment is set up in a special inspection institution, and it is necessary to carry the inspected items to carry out inspections. During this process, there are issues such as the safety and confidentiality of the inspected items.
[0004] Moreover, when an unexpected problem occurs and on-site inspection is required, the inspection service cannot be provided in time. If the CT equipment is simply moved to the required place, it will face the problem of radiation overdose

Embodiment 1

[0027] The mobile CT inspection device of the present invention includes a flow room 1 and a scanning frame 2 arranged in the flow room, the flow room is provided with an outer lead protection layer 10, and the scanning frame includes a casing 21, The slip ring arranged in the casing and the inner lead protection layer 3 arranged inside the casing.

[0028] Wherein, the outer lead protective layer is 0.5-10mm, preferably 1-5mm, such as a 3mm thick lead plate fixedly arranged on the inner wall of the mobile room or in the interlayer, and the inner lead protective layer is 0.5-10mm, preferably 2-4mm, such as a 2mm lead plate is used to cover the transmitting source and the receiving end, preferably, the thickness of the outer lead protective layer is 3mm, and the inner lead protective layer is 2mm.

[0029] The CT inspection device of the present invention is provided in mobile boxes such as containers, cargo boxes, carriages, etc., so that it has high flow adaptability, and ado...

Embodiment 2

[0031] The mobile room is preferably a container 1, which adopts a standard volume and is convenient for transportation. The two ends of the length direction of the container are provided with side-by-side doors, and the space in the box is divided into scanning frame cabins 11, The mobile bed cabin 12 and the operating cabin 13 of the fixed mobile bed 4, certainly, reception room 14 can also be set, and described reception room and operating cabin, the partition between the operating cabin and the mobile bed cabin is provided with isolation door, so A through hole corresponding to the scanning frame is provided on the partition between the scanning frame cabin 11 and the moving bed cabin 12 so that the moving bed can extend in. Preferably, the scanning frame is fixed to the partition. Wherein, in order to improve the protection effect, the scanning frame cabin is provided with an outer lead protective layer. Of course, in order to improve the overall protection effect, the cor...

Embodiment 3

[0034] Specifically, on the basis of the above-mentioned embodiments, the casing is formed with an inner chamber for accommodating the slip ring, and the inner lead protection layer is cylindrical and fixed to the wall of the inner chamber. Connect and shield the slip ring, the transmitting source and the receiving end. Of course, the inner lead protective layer can also adopt a structure directly inside the casing, and further the inner lead protective layer includes a cylindrical main body and ring-shaped end sides arranged at both ends of the casing, that is, the maximum range To provide protection, the hole in the middle of the end of the ring side is the inspection window.

[0035] In the way of fixed connection with the casing, the inner lead protection layer can be directly set in a cylindrical shape or a cylindrical shape with an avoidance structure such as an avoidance hole to protect the overall radiation space and effectively reduce radiation leakage. Moreover, the ...

Abstract

The inVention discloses a flow-type CT examination deVice, which comprises a flow room and a scanning frame arranged in the flow room, wherein the flow room is proVided with an outer lead protectiVe layer, and the scanning frame comprises a shell, a slip ring arranged within the shell and an inner lead shield for shielding an emission source and a receiVing end therein. The CT examination deVice has high flow adaptability through the arrangement of a mobile room, such as a container, a cargo box, a carriage and the like, moreoVer, a container integrated structure is used, an examination and asupport circuit are integrated together, the requirements of flow use is largely met, a two-stage protectiVe measure is adopted. The inner lead protectiVe layer is adopted for leakage radiation absorption aiming at the key radiating area. Meanwhile, an outer lead protection layer is used on the side wall and the top wall of the flow house respectiVely, and if necessary, an outer protectiVe layer can be arranged on the bottom plate, and two-stage protection is proVided, the external protection effect is effectiVely improVed, and the radiation dose inside the flow room can be reduced as much aspossible.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a mobile CT inspection device. Background technique [0002] CT equipment is mainly composed of the following four parts: scanning, computer, power supply and auxiliary equipment. The scanning part is composed of X-ray tube, detector and scanning frame; the computer system stores and calculates the information and data collected by scanning. The X-ray beam scans across a certain thickness of the human body or cargo through the collimator. Each detector receives the attenuation signal of the X-ray through the tissue or cargo, converts it into an electrical signal, and then converts it into a digital signal through analog-to-digital conversion ( That is, the original data) and stored in the memory. [0003] At present, the commonly used devices for installing high-precision DR (Digital Radiography) / CT (Computed Tomography) system equipment are in fixed house...
