Abstract
A method of reducing the radiation of OCT equipment DVI video interface, it is characterized in that installing conducting foam additional on the DVI interface of display, it connect the DVI interface of display effectively with metal decking, when DVI connector is connected to the DVI interface of display, the shielded layer on DVI cable can be operatively connected on metal decking.The method of the present invention is simple, good reliability, easy to operate, at low cost, amount of radiation can be made up to standard without making improvements to circuit and hardware, is lower than standard specified value.
Description
Technical field
The present invention relates to a kind of display technology, especially a kind of medical display radiation protection technology is specifically a kind of
The method for reducing the radiation of OCT equipment DVI video interface.
Background technique
Currently, intravascular computed tomography (SPECT) system cooperation imaging catheter is designed for the imaging to the blood vessel of diameter > 1.5mm,
It realizes the precise measurement to lumen diameter, area, the imaging to vascular wall and blood vessel implant structure, and then distinguishes patchiness
Matter and the evaluation for being used for blood vessel implant (bracket, filter, spring ring etc.).
Intravascular computed tomography (SPECT) system is based on intravascular optical coherence tomography (Optical Coherence
Tomography, OCT) technology combination imaging catheter system, OCT technology be used as after intravascular ultrasound (Intravascular
Ultrasound, IVUS) imaging technique in the new coronary artery of one kind that occurs afterwards, compared with IVUS, OCT high resolution ratio
Make it in evaluation vulnerable plaque, instruct stenter to implant, especially in acute coronary syndrome (Acute Coronary
Syndrome, ACS) in diagnosis and treatment using of increasing concern.
2011, to IVUS in American Society of Cardiology/American Heart Association (ACCF/AHA) Percutantnoeus coronary intervention guide
The recommendation etc. applied in percutaneous coronary intervention (pci) (Percutaneous Coronary Intervention, PCI)
Grade is IIa, and to the recommendation grade of OCT because evidence-based medical deficiency is not yet established.2012, CLI-OPCI studies have shown that
Compared with the PCI treatment of simple radiography guidance, the PCI treatment under OCT guidance can significantly improve patient's prognosis.Then, 2013
Year European Society of Cardiology is about in Stable coronary heart disease administration guide, and OCT is for assessment lesion characteristics and optimization stenter to implant
Process is classified as IIb grades of recommendations (level of evidence is B grades), and overall evidence level is equal to IVUS.2014, heart of Europe disease
In the myocardium revascularization guide of meeting/Europe cardiothoracic surgery association (ESC/EACTS), recommendation grade of the OCT to optimization PCI is promoted
Recommend to the IIa grade being equal with IVUS.The ILUMIEN I that delivers for 2015 is research shows that PCI is preoperative and/or postoperative row OCT inspection
Look into the strategies of interventional treatment that can influence patient.ILUMIEN II result of study shows that OCT is not inferior in terms of instructing stent expansion
IVUS.With the continuous renewal of OCT technology and the announcement of more perspective study data, OCT is led in coronary intervention
Status in domain will further be promoted.
It has been found that existing OCT equipment is in radiation-emitting test, by B class standard, complete machine is in horizontal 2m
At 651MHz；At vertical 2m 810MHz, amount of radiation is exceeded.It is 4 times and 5 frequencys multiplication of 162MHz respectively！As shown in Figure 1, and
162Mhz is the clock frequency that can be used in image processing unit (GPU)！Thought it is caused by vision signal
It radiates exceeded, it is necessary to solve.
Summary of the invention
The purpose of the present invention is for existing OCT device display horizontal 2m 651MHz at vertical 2m 810MHz
Place, the amount of radiation that can lead to the problem of 4 times and 5 frequencys multiplication is exceeded, invents a kind of side of reduction OCT equipment DVI video interface radiation
Method.
The technical scheme is that
A method of the radiation of OCT equipment DVI video interface being reduced, it is characterized in that installing additional on the DVI interface of display conductive
Foam connect the DVI interface of display effectively with metal decking, when DVI connector is connected to the DVI interface of display, DVI
Shielded layer on cable can be operatively connected on metal decking.
Using the DVI cable of no adapter as video signal transmission wire.
The conducting foam is made of sponge with the conductive metal silk screen for being wrapped in sponge surface, which opens up
There are the opening and screw fixed hole on the DVI interface for being sleeved on display.
Beneficial effects of the present invention:
The present invention by verifying repeatedly, it is believed that radiating at display exceeded is existed when because vision signal entering display interface device
It leaks and causes to radiate, therefore connect the shielded layer of video signal cable effectively with metal decking realization by installing conductive tie layers additional
It connects, the vision signal for generating Video radiation enters metal decking, no longer generates leakage.The radiation leakage for solving interface is asked
Topic.
The method of the present invention is simple, good reliability, easy to operate, at low cost, it is not necessary that circuit and hardware are made improvements and can be made
Amount of radiation is up to standard, is lower than standard specified value.
Detailed description of the invention
Fig. 1 is that the present invention does not install (the lateral fold line table in figure of 10 meters of method darkroom radiation value measured result figures before conducting foam additional
Face B class standard value).
Fig. 2 is the structural schematic diagram of conducting foam of the invention.
Fig. 3 is that the present invention installs 3 meters of method darkroom radiation values actual measurement structural schematic diagram after conducting foam additional, and lateral fold line is in figure
B class standard value.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figs. 1-3.
A method of the radiation of OCT equipment DVI video interface is reduced, on the one hand takes and adds on the DVI interface of display
Conducting foam shown in Fig. 2 is filled, connect the DVI interface of display effectively with metal decking, when DVI connector is connected to display
DVI interface when, the shielded layer on DVI cable can be operatively connected on metal decking.On the other hand it will originally install
The more video signal cables with connector of use are facilitated to be changed to single video signal cable, conducting foam of the invention such as Fig. 2 institute
Show, it is made of sponge with the conductive metal silk screen for being wrapped in sponge surface, which, which offers, is sleeved on display
Opening and screw fixed hole on DVI interface, conducting foam realize metal decking, video cables shielded layer after screw squeezes
With effective electrical connection of DVI interface.By upper art treated actual measurement radiation value it is as shown in Figure 3.Fig. 3 is that 3 meters of institute is measured in Shenzhen
Method darkroom measured result, the low 10dB of B class standard ratio A class, horizontal sweep result and vertical scanning are as a result, on a figure, not
More than B class standard.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
