Description

Technical Field

[0001] The invention relates to the field of nuclear medicine examination, and in particular to a conduction cabinet for protecting radiation in a nuclear medicine PET-MR examination room. Background Art

[0002] In nuclear medicine, the effect of MRI examination is to stimulate hydrogen protons in the body through magnetic field, and obtain images after computer processing according to different durations. Since no radiation is generated during the whole process, only signal shielding is required when constructing the MRI examination room. In terms of space, the MRI examination room includes not only the large room where the MRI detector is placed (usually called the examination room), but also a small room for circuit control required by the detector and other equipment. There is a conduction port for transmitting signals between the two rooms, and a conduction plate is set at the conduction port. At present, the purpose of magnetic shielding of MRI detectors is often achieved by magnetically shielding the two rooms at the same time. For the sake of aesthetic design, a wall cabinet covering the conduction plate will be set on one side of the large room. If the conduction plate needs to be inspected, the wall cabinet is opened directly, and if the control circuit needs to be inspected, the small room is directly entered.

[0003] PET-MR is a large-scale functional metabolic and molecular imaging diagnostic equipment that is an integrated combination of positron emission tomography (PET) and magnetic resonance imaging (MR). Compared with MRI, PET-MR is a more advanced and accurate detection method. In addition to being used for examinations of ordinary patients, it is also often used for examinations of patients injected with radioactive agents. Therefore, based on both detection and application considerations, when constructing a PET-MR examination room, not only signal shielding but also radiation protection is required. The current protection idea is usually based on the MRI magnetic shielding trajectory (overall protection of the two rooms). Such protection has a defect, that is, no matter whether it is a major overhaul or a minor overhaul, in order to avoid radiation exposure to maintenance personnel, the entire equipment needs to be shut down in advance, while some overhauls do not necessarily have to be carried out under shutdown. The shutdown process is lossy for both hospitals and patients. Therefore, this application has developed a conduction cabinet for a PET-MR examination room based on nuclear medicine, which can better solve the above problems. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, the present invention provides a conduction cabinet for a nuclear medicine PET-MR examination room, which has the advantages of good radiation protection effect, maintenance without stopping the machine and low protection cost.

In this specification, the schematic representation of the above terms does not necessarily target the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0028] like Figure 1-3 As shown, in this embodiment, the conduction cabinet for a nuclear medicine PET-MR examination room includes a keel frame 1, a lead protective layer 2 and an outer decorative layer 3;

[0029] The keel frame 1 is arranged at a corner of the inspection room 4 so that its adjacent two sides are fixed against the wall, and the other two sides are respectively set as the front side and the side. The upper space 11 and the lower space 12 are separated in the keel frame 1. The lower space 12 is separated into a front area 121 and a rear area 122 in the front and rear. The keel frame 1 at the rear side of the rear area 122 is provided with an inspection port 123 cooperating with the conduction plate. The keel frames in front and behind the front area 121 are respectively formed with an inlet and outlet 124. The front area 121 is respectively formed with a first front area 1211 close to the side and a second front area 1212 away from the side on both sides of the inlet and outlet, and a hoisting area 1213 is formed above the inlet and outlet.

[0030] The lead protective layer 2 includes a first lead plate 21 arranged on the side of the keel frame 1 corresponding to the lower space 12, a second lead plate 22 arranged on the front side of the keel frame 1 corresponding to the first front area 1211 and the hoisting area 1213, a third lead plate 23 arranged on the keel frame 1 at the rear side of the second front area 1212, a fourth lead plate 24 arranged on the keel frame 1 at the bottom of the upper space or the top of the lower space, and a lead protective door 25 arranged in the front area to cooperate with the two inlets and outlets. The first lead plate 21 and The upper end of the second lead plate 22 is higher than the top of the fourth lead plate 24. The lead protection door 25 includes a plurality of sliding door panels arranged front and back. Each sliding door panel is slidably arranged left and right by a hanging rail assembly arranged at the top of the hanging area 1213. The hanging assembly can specifically adopt a track and a hanging wheel structure. When the plurality of sliding door panels are pulled apart in sequence, they can cooperate with the first lead plate 21, the second lead plate 22, the third lead plate 23 and the fourth lead plate 24 to isolate the radiation between the rear area 122 and the inspection room.

[0031] The outer decorative layer 3 includes decorative panels ( Figure 3 In order to present the first lead plate, the side decorative plate is not installed yet). In addition, Figure 4 As shown, decorative panels may also be provided on the inner walls of the rear area and the front area as required to form an inner decorative layer 4.

[0032] Next, the advantages of the above-mentioned configuration of the conduction cabinet will be described in detail. The examination room mentioned in the description specifically refers to the room where the examination equipment is placed. In hospitals, PET-MR examination equipment is generally placed in the center of the examination room, so the center is the radiation source. For the radiation source, the conduction cabinet of this application realizes efficient radiation protection in the lateral direction for the rear area through the first lead plate 21, the second lead plate 22, multiple sliding door panels, and the third lead plate 23 in sequence. Specifically, since the conduction cabinet is set in a corner of the examination room, the gaps between the multiple sliding door panels and between them and the second lead plate 22 and the third lead plate 23 are all in the direction away from the radiation source, which will effectively prevent the rays from entering the rear area 122 through the gaps. In addition, since the walls of the inspection room are protected by lead plates, combined with the side protection formed by the present application and the top protection of the fourth lead plate 24, the radiation source's rays can be effectively isolated from entering the rear area, which is equivalent to forming a safe area for inspection personnel to enter. In this way, for some inspections that do not require shutdown, the conduction plate and the circuits and other structures in the room behind the conduction plate can be inspected, thereby saving more time for examining patients.

[0033] In addition to the above advantages, the conduction cabinet of the present application also has the advantages of saving cost and space. Specifically, the use of multiple sliding door panels can save space as much as possible, so as to better realize the setting of the door gap away from the radiation source; the conduction cabinet is set in a corner, which can save lead protective materials on two sides.

[0034] In one specific embodiment, Figure 4-5 As shown, in order to arrange the lines connecting the inspection room and the conductive plate, a threading hole 125 is also provided at the top of the keel frame 1 corresponding to the rear area 122, and a lead protective cover 27 covering the threading hole 125 is provided in the upper space 11, and a threading hole is provided on the rear side of the lead protective cover 27. Such an arrangement can better shield radiation, and the lines passing through the rear area can be arranged along the wall of the inspection room corresponding to the upper space, and other required equipment can also be arranged in the upper space as needed.

[0035] In one specific embodiment, since the conductive plate will generate heat during use, lead shutters may be provided on the sliding door panel to accelerate the heat dissipation. Figure 3 shown.

[0036] In one specific embodiment, at least a portion of the sliding door panel can be embedded in the second front area 1212 after being opened.

[0037] In one specific embodiment, Figure 2-3 As shown, in order to better protect the bottom gap of the door, a front crossbeam is set at the bottom of the entrance and exit on the front side of the front area, and a fifth lead plate 26 is set on the front or rear side of the front crossbeam to prevent the rays from entering the rear area through the bottom gap of the door as much as possible. In addition, a groove can be opened on the ground, and a lead plate can be laid in the groove to achieve the bottom gap protection of the door.

[0038] In one specific embodiment, it is preferred that the lead protection door is provided with three sliding door panels.

[0039] In one specific embodiment, the upper end of the keel frame 1 extends to the top of the inspection room and is fixed to the top keel of the inspection room, which will greatly increase the firmness of the overall structure, and the upper space formed is convenient for accommodating other required equipment, such as cooling fans, etc.

[0040] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.

[0041] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
