Microwave RF technology in medical applications

Time：2023-07-27

For many years, Microwave Devices Corporation has been supplying devices for medical imaging applications such as magnetic resonance imaging systems. While imaging applications continue to offer solid opportunities, many other medical applications are beginning to open their doors to wireless microwave and RF technologies. For example, remote monitoring enables doctors at home to wirelessly send health conditions such as blood pressure and pulse to them. Other innovations are also helping hospitals and medical centers track the location of assets and individuals. Among the existing imaging markets and the new opportunities that wireless technology is creating, the medical industry has become a real new market that many microwave and RF companies are targeting. Fortunately, many of these opportunities only require these companies to leverage their existing expertise in telecommunications and wireless LANs.

The

use of imaging devices such as MRI is increasing, and more than 60 million MRI diagnoses are now performed worldwide each year. They are commonly used to diagnose various diseases and injuries such as Alzheimer's (Alzheimer's), cancer cells, and torn ligaments. The imaging system uses a variety of RF/microwave devices, including oscillators, transmitters, and antennas. For example, Analog Devices now offers the AD5791, a 20-bit data converter (DAC) designed to increase imaging resolution.

The AD5791 has true parts per million (ppm) resolution and accuracy. The AD5791 has a relative accuracy specification of ±1LSBDNL, ensuring operational consistency. The DAC has only 0.025ppm of low-frequency noise and 0.05ppm/C of output drift. This low noise reduces unwanted image artifacts, which reduces the need for multiple MRI scans, so patients can be seen in less time. The outputs can be configured in the standard unipolar (+5V, +10V) or bipolar (±5V, ±10V) ranges. The AD5791's 3-wire serial interface operates at 50MHz.
