Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of display screen of magnetic resonance compatible.
Background technology
In MR imaging apparatus operating process, display screen can produce electromagnetic signal, and the generation of electromagnetic signal can be to magnetic
Resonance image quality has an impact, so shielding electromagnetic signal turns into key.
Utility model content
The technical problem that the utility model solves is to provide a kind of display screen of magnetic resonance compatible, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
The technical problem that the utility model solves realized using following technical scheme, a kind of display of magnetic resonance compatible
Screen, including：Front frame, inwall, bonnet, internal circuit, projection, groove, fixing hole, the display screen are shielded using overall parcel,
There are some projections inside front frame along inwall, the inner wall thickness selects thin-walled and leaves 4mm thickness grooves, and the bonnet leaves
The connecting hole that fixing hole, signal and power supply pass through, the internal circuit mainly has is converted to electric signal by external fiber signal
Optical fiber changeover circuit and the drive circuit of driving display screen work.
Electromagnetic shielding glass is used before the front frame, copper mesh shirt rim is connected with frame.
The beneficial effects of the utility model are, the display using the shielding integrally wrapped up, make whole display screen into
For an equipotentiality body.It is connected before front frame using electromagnetic shielding glass, copper mesh shirt rim with frame, is ensureing light transmittance as far as possible
In the case of increase the shielding properties of front frame, when select inner wall thickness, selection but leaves groove at thin-walled, is contacted with bonnet increase
Area, there is projection at surrounding inwall, fix bonnet with front frame first, playing, second, contact of the increase bonnet with front frame, enhancing
Bulk shielding performance, effectively reduce interference of the display screen in Magnetic Resonance (MR) Room/ MRI Room to magnetic resonance imaging.
Brief description of the drawings:
Fig. 1 is the utility model structure diagram；
Front frame 1, inwall 2, bonnet 3, internal circuit 4, projection 5, groove 6, fixing hole 7.
Embodiment：
Embodiment is given below so that the utility model to be specifically described, it is necessary to it is pointed out here that be following implementation
Example is served only for that the utility model is further described, it is impossible to is interpreted as the limitation to scope of protection of the utility model, the neck
Some nonessential modifications and adaptations that the person skilled in the art in domain makes according to the utility model content to the utility model are still
Belong to the scope of protection of the utility model.
As shown in figure 1, a kind of display screen of magnetic resonance compatible, including：It is front frame 1, inwall 2, bonnet 3, internal circuit 4, convex
Post 5, groove 6, fixing hole 7, the display screen are shielded using overall parcel, have some projections 5 along inwall 2 inside front frame 1,
The thickness of inwall 2 selects thin-walled and leaves 4mm thickness groove 6, and the bonnet 3 leaves fixing hole 7, the company that signal and power supply pass through
Hole is connect, the internal circuit 4 mainly has the optical fiber changeover circuit and driving display screen that external fiber signal is converted to electric signal
The drive circuit of work, front frame 1 above use electromagnetic shielding glass, and copper mesh shirt rim is connected with frame.
The beneficial effects of the utility model are, the display using the shielding integrally wrapped up, make whole display screen into
For an equipotentiality body.It is connected before front frame using electromagnetic shielding glass, copper mesh shirt rim with frame, is ensureing light transmittance as far as possible
In the case of increase the shielding properties of front frame, when select inner wall thickness, selection but leaves groove at thin-walled, is contacted with bonnet increase
Area, there is projection at surrounding inwall, fix bonnet with front frame first, playing, second, contact of the increase bonnet with front frame, enhancing
Bulk shielding performance, effectively reduce interference of the display screen in Magnetic Resonance (MR) Room/ MRI Room to magnetic resonance imaging.
General principle and principal character of the present utility model has been shown and described above.The technical staff of the industry should
Solution, the utility model are not restricted to the described embodiments, and simply illustrate that this practicality is new described in above-described embodiment and specification
The principle of type, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various changes and modifications,
These changes and improvements are both fallen within claimed the scope of the utility model.Claimed scope of the present utility model is by appended
Claims and its equivalent thereof.
