To ensure optimal functionality of MRI scanners, hospitals use spectrum analyzers to measure and analyze signals while identifying any interference that could disrupt their accuracy and performance.

The spectrum analyzer is used by hospital technicians to observe a vast array of radiofrequency signals at a specific time frame, making them ideal for equipment testing, monitoring, or calibration. They’re manufactured and distributed by technological equipment specialists such as Keysight and similar providers, and they can be purchased brand-new or used.

The advantages that Keysight spectrum analyzers offer to patients and hospitals will be discussed in this article. Continue reading to learn more about this tool and its benefits.

Defining Spectrum Analyzers And Their Functions

Spectrum analyzers are manufactured by various companies and come in different formats. The common design of analyzers includes the RF detection device housed in a container and mounted in a short rack. Other designs are more suited for portable use, or made as attachments to equipment and computers. The common denominators of these designs include the monitoring screen, control buttons, and knobs.

A spectrum analyzer is used to measure the frequency of a radio or audio signal in different settings such as electrical, laboratory, engineering, and music. In medical facilities, these devices can identify the efficiency and performance of medical equipment using RF such as MRI scanners and RFID-tagged items. Moreover, spectrum analyzers can also define interfering signals, which is useful for testing, installation, troubleshooting, or calibrating devices.

The Benefits Of Using Keysight Spectrum Analyzers In Healthcare

Keysight Spectrum analyzers make a wise investment in healthcare facilities because of the value they add for hospitals and patients. Here are some of the ways these devices become advantageous to healthcare:

  1. Augments Interference Detection And Management

Most healthcare facilities or institutions utilize medical equipment that uses radiofrequency such as MRI scanners and radio-frequency identification (RFID) trackers. For instance, MRI scanners use radiofrequency pulses to trigger proton movement against the magnetic field created by the same device. This function allows the scanner to create accurate imaging of the body and its internal organs. For optimal functioning, the radiofrequency current should flow unimpeded through the patient’s body, which is why signal interruptions during MRI scans should be prevented.

Meanwhile, RFID trackers are used for various machines, vehicles, and medical equipment in hospitals. One example is the RFID band worn by patients around their wrists. The RFID band serves as the patient’s identification in the hospital, and it carries information such as their name, medical record, and other details relevant to their treatment. Through RFID bands, the hospital is able to track the patient for their own safety and security.

To boost the functionality and effectiveness of these devices, it’s essential to properly manage the radio signals they receive and improve the detection of any interference. With a spectrum analyzer, hospital technicians can differentiate interference and monitor the signals from the medical equipment. They can also make the necessary adjustments to remove the source of interference and prevent further disruptions.

As there may be fewer instances of interference, the results of any measurement, data collection, or testing using medical devices will be more accurate. Also, the processes will be smooth and hassle-free, making spectrum analyzers significantly beneficial for patients and hospitals alike.

  1. Supports Wireless Signal Monitoring

It’s common for hospitals and other medical facilities to have complex structures built with specialized construction materials to facilitate various kinds of treatments. Because of the nature and design of these facilities, some rooms may have radio path loss, which means that equipment utilizing radiofrequency may have poor connection. For instance, a room made with thicker concrete may suffer from attenuation, making it unideal for MRI installation or RFID use.

It can be challenging to ensure that all rooms or areas will have the same strength of wireless signal coverage required to support medical equipment that needs stable connectivity to function. However, facilities need reliable signal coverage, especially during emergencies or when accommodating high patient volumes.

To minimize attenuation and ensure robust connectivity, technicians can utilize spectrum analyzers when analyzing signal strength and detecting any disruptions to the connection. For instance, the technicians can perform tests in rooms where MRI or CT scans are conducted before patients are accommodated to ensure that the testing will be accurate, comfortable, and free of disruptions.

  1. Enhances Troubleshooting And Maintenance Processes

Keysight spectrum analyzers also enhance troubleshooting and maintenance processes, which can be especially helpful for field technicians in charge of fixing damage or testing the equipment. For one, the analyzers come with a display screen, making it easier for technicians to see and read data relevant to their tasks efficiently. Because of this feature, they have to strategically place the display screen on a spot where they can conveniently read it while adjusting the machinery they’re working on.

Spectrum analyzers can cover several radio channels at a given time, which allows technicians to scan them simultaneously. While there may be several pieces of equipment in a hospital that frequently use radiofrequency, it’s possible to detect the sources to see if there are any unwanted signals with the help of the analyzer.

Improving these processes can benefit patients and hospitals for several reasons. For one, improved troubleshooting prevents patient testing or treatment schedule disruptions as the

hospital will experience fewer equipment malfunctions. In turn, patients can receive medical care without delay. Meanwhile, hospitals can avoid costly repairs while preventing errors or delays in their patient services, which will boost their service quality.

  1. Increases Site Survey Accuracy And Efficiency

Apart from regular servicing of MRI scanners or RFID equipment, hospital technicians also conduct site surveys from time to time. Site surveys help ensure that testing or diagnostic rooms with RF-based medical equipment get protection against stray radio waves. These unwanted signals can be detrimental to the accuracy of the diagnostic results and to the general effectiveness of the devices, which is why it’s essential to detect them immediately and block their sources.

For instance, MRI rooms are designed to be safe from RF signals such as radios or mobile phones. Besides the structure that shields the scanner from these interferences, hospitals also assign technicians to conduct surveys to ensure that the equipment is safe from disruptions. According to a 2020 study, the most effective electromagnetic shield is made from a combination of copper and zinc. However, the effectiveness of shields may degrade over time, which is why periodic testing or surveying is essential.

However, traditional testing methods can be costly, time-consuming, and ineffective. Thus, spectrum analyzers are used because they’re portable and easy to set up. With testing becoming more manageable, more effective, and more convenient, hospitals and patients can benefit from improved accuracy and efficiency of medical diagnosis using monitoring or measuring health devices.
