ABOUT ARTENG RF CAGES

Arteng has created its RF cage solution with competitive prices and incomparably short lead times without sacrificing quality. To achieve this challenging goal, we have established our 300 RF Cage/year production and testing facility in Istanbul and we can expand it further. We created our demo RF cafe and presented it to Siemens Turkey. We started supplying after acceptance and since then we have successfully built more than 150 RF cages nationwide and abroad.
Siemens Turkey honored Arteng as a supplier of the year.

Production and Testing Facility:
One of our goals was to be competitive on price and our key point was to be a manufacturer of specific parts. Thus, we established our sandwich RF panel production and testing facility in Istanbul. To further develop our cages, we conduct R&D, test all cages before we move them to the site, and train our future fitter at this facility. It has a logistical advantage due to its location on the European side of Istanbul and its proximity to the 3rd airport. In addition, we have created a sustainable supply chain to prevent a shortage of raw materials.

Sandwich Panels
The standard package is a tailored solution for local needs, each RF cage is unique due to its custom and site-specific design. After the frozen design is procured from the Project Managers, we are ready to move on to the production-specific preliminary preparations and take the demand to the production stage. The life-size mesh is built as a massive 3D puzzle to run shielding quality tests at the test facility after simulation. If the test is successful, the cage receives its serial number and stamp. Each panel is then coded according to its position in the puzzle, and the entire puzzle is ready to be packed accordingly. Thanks to this plan, on-site installation time was reduced by 46%.
Meanwhile, demand is increasing day by day, we also use the test facility as a training center for our future installation teams.

Under-cage insulation material
When the materials and assembly crew first arrive on-site, we must electrically isolate the Cage from everything around. We provide the necessary electrical isolation with a 3mm isolation membrane and this is included in the standard package.

Turning on and connecting the RF Filter
The next feature is the opening of the RF filter. The RF filter is one of the key elements in MRI setups to achieve proper RF isolation. The RF filter is a heavy element depending on the magnet type. The filter opening and connection holes must be machined precisely and the filter carrying panel must be strong enough to balance the weight.

Soundproof Material on Walls
MRIs can reach very high sound levels of 130db, which is almost as loud as a motorcycle running too close to you. Therefore, acoustic sound insulation is also very important for clinicians. The cabinet itself also helps with this purpose because of its different layers. However, 5 cm of rock wool material is also added to achieve normal hospital noise levels.

Extinguishing Pipe from Machine to Cage Boundary by PM Design
The standard package includes extinguishing piping from the machine to the outside of the Cage. The length and size of the extinguishing pipe differ from site to site. For example, it may be 15 cm in diameter on one side and 7 meters in diameter on another site, 60 meters and 40 cm in diameter. So, to have a standard in this material and get a finished RF Cage, we terminate the pipe at the cage boundary and provide a suitable flange to connect the rest of the pipe.

RF Shielded Window
The key point in window shielding is to achieve a transparent view and suitable shielding at the same time. There must be some conductive material inside the window for proper RF shielding. The very special conductive material in our windows is RF proof but also nearly invisible. The feedback on windows is quite satisfactory.

MR Compatible Air Ducts and Honeycomb Grilles
No air conditioners can operate in MRI rooms, but we must still allow a certain amount of air circulation in the cage to maintain air quality and temperature balance. The air is circulated through honeycombs, which also guarantees RF shielding. There must be a certain distance between the exit and the entrance of the RF room to take advantage of the cold air. Therefore, MR compatible air ducts are used to position these outlets at an appropriate distance.

INTERIOR DESIGN

Interior design is one of the most important parts because when such a high-tech machine enters the room, the room is expected to be welcomed in the same way. Arteng Yapı can provide the following.
Suspended Ceiling
The suspended ceiling is made of 60×60 acoustic plates to allow the service to reach everything on the ceiling without damaging it. However, most of the customers demand a stretch ceiling that can be supplied in the desired color and pattern. In these cases, we bring the stretch ceiling to the appropriate position and the rest of the ceiling is still 60×06 sheets.

Easy-to-Clean Wallcoverings and Aluminum Separators

We supply 8mm thick MDF wallcoverings in the standard package. This material is easy to install and maintain. Also, if the RF cage needs to be relocated in some way, these caps can be reused at the new site.

Aluminum Separators:

Door separators are also part of the room look. We have chosen an MRI-compatible and durable Aluminum material and the feedback is satisfactory.
MRI Compatible Led Lights and Internal Electrical Connections

We supply MR-compatible, long-life-performing led lights. The lights are powered by DC Voltage, no harm to the human body. Therefore, no specialist is needed in the case of replacement. We included it in the standard package. Electrical connections inside the RF room will also be made by our installation experts.

RF Filter Cabinet
The mesh part of the RF filter contains many cables coming out of the visible height. That's why we supply and install RF filter covers to cover this part and keep the filter working properly.

ARTENG YAPI RF CAGE COMPONENTS

Cable ducts inside the RF room
There is usually some cable extension left in the magnet room, depending on the magnet room cable set. Some of these cable sets carry a large amount of power and require the appropriate infrastructure that the RF cage must provide for each cable to be routed correctly. The standard package also includes MRI-compatible cable channels with the described features.

Electrical filters
No current-carrying electrical element can enter the magnet chamber without suitable filters. In most cases, 4 pairs of power lines are required in the RF cage. We provide 5 pairs to have a spare pair in case the site needs an extra line for a special application.

Waveguides for non-electric entry
Although the original waveguide is located in the technical room to the magnet room RF filter, clinicians often require another waveguide from the control room to the magnet room for certain applications. We supply and install a pair of 7 cm waveguides on the control room wall.

Medical gas penetration filters
Medical gases are transferred through copper pipes throughout the hospital. And copper has the potential to interfere with RF, so these pipes must be filtered. Penetration filters are the solution here. Three types of medical gases are generally used for certain MRI exams, but we pack 5 filters in the standard package to cover more applications. MRI ambiance systems have been in demand in the market recently, and these filters are also suitable for ambient system optical cabling.

Medical gas pipes in the RF room
When the medical gases need to be directed to the final outlets after the gas penetration filters, the pipes inside the RF room are also included in the standard package.

Medical gas panel with up to 5 outlets on the finished wall
 The location of the medical gas panel inside the RF room is specified in the project design file. In most cases, it is located near the intersection of the magnet hole and the patient table. Also, each hospital has standards for their gas outlets such as British, French, or American standards, so we supply and install medical gas panels and outlets accordingly, depending on the predefined standard.

Baseplate Installation
 All magnets, except Essenza, have a baseplate that must be attached during the RF Cage installation step, as it must be under the floor cover and fixed to the floor of the RF Cage. We place the base plate in the standard package.

RF Shielding Efficiency Report
Once all RF cage-related installations are complete, it's time to run the standard RF Cage efficiency test to ensure the job is done properly and the cage is ready for delivery. The cage should reach our threshold of protection efficiency of 90db. We share the report and video while examining the RF cage with the project manager.

ARTENG YAPI RF CAGE

Magnetic Field Protection
In some cases, the PM must suppress 0.5mT or even 0.3mT lines to ensure that the strong magnetic field will not affect anything or anyone around it. To achieve this goal, PM requires iron shielding with a ready-to-implement project. We supply and install the iron shield with the appropriate material and apply anticorrosion with the PM project file.

Supply and installation of the extinguishing pipe
If the route and diameters of the extinguishing pipe are defined, Arteng can supply the pipe by the predetermined standard and assemble it on site. In addition, rubber insulation, yellow tape labeling, and pipe finishing in required dimensions can be supplied and assembled as standard hoods, conical and louvered panels. We've had all kinds of experiences with over 150 RF cage installations. The only prerequisite here is to have a predefined route and to know how to traverse it.

RF Lattice leveling
RF lattice is a 3D room consisting of a floor, 4 walls, and a ceiling. According to the cage type, the floor has a certain height. In some cases, the hospital requires that there be no level difference between the interior of the RF cage and its surroundings after all installations have been completed. For example, if the sandwich panel is an RF Cage, the floor height will be 3.5cm, so we will require a level of -3.5cm relative to the surrounding floor along with the RF Mesh. We still have construction genes from other businesses of our Arteng, so we can also provide such a service if needed and ordered.

Cable channels in the MR technical room
Many cables are passing through the RF filter. End users or hardware installers and service professionals often want a well-organized ceiling. To meet such a demand, we can also supply special cable ducts to the ceiling of the technical room and order such a service if necessary.

Long RF Filter cabinet
The RF filter in the magnet chamber has an extension that must be closed for aesthetic reasons. In some cases, a cabinet is also needed to store service-related equipment, such as a phantom, in the magnet room. We came up with this solution and named it a long RF filter cabinet. The ordinary RF filter cabinet just covers the RF filter and hangs above ground. The tall cabinet starts from the magnet chamber floor and covers the RF filter as a unique cabinet. The upper part still covers the RF filter, the lower part is used for service equipment.

Custom-designed Coil Trolley
In some facilities, we were asked to provide a custom-designed Coil Trolley as clinicians requested the specific needs of their sites. We can design and supply any shape of a custom-designed coil car.

Ceiling mounted Barrisol
Barrisol adı verilen arkadan aydınlatmalı görsel yardımcıları duvara veya tavana temin edebilir ve monte edebiliriz.
