Laws and Regulations

  • This equipment complies with relevant regulations regarding the marketing of equipment. Operators are obliged to comply with such regulations.
  • This device complies with Part 15 of the FCC Rules.Operation is subject to the following two conditions:
    • This device may not cause harmful interference, and
    • This device must accept any interference received, including interference that may cause undesired operation.
  • This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. Minimum distance of 20cm between the radiator and the body should be maintained during operation.
  • This equipment is only suitable for fixed, extremely short-range surface respiratory motion signal detection in medical imaging equipment. It is not suitable for satellite, aircraft, and vehicle-mounted radar systems.

Product Use and Maintenance
In case of sensor function problems, UIH service engineers will disassemble and replace the sensor. The millimeter wave sensor is installed inside the Volume Transmit Coil (VTC) of Magnetic Resonance Imaging System (MRI). The use condition is a RF shielded location environment. The millimeter wave sensor is used to provide the physiological parameters of the patient’s respiratory movement, collect the respiratory signal and transmit it to the system, and realize the gated triggered scanning of the system to reconstruct the image.The equipment must be professionally installed and installation must be controlled. The device sold to dealer who hires installers with licensed professionals and special training.Imaging-Healthcare-mm-100-Millimeter-

After the system is powered on, the sensor directly starts by itself, and collects respiratory signals and uploads data according to the program. The user only needs to view the waveform and configure the specific trigger sequence in the waveform display position on the operation computer interface of MR system. The area of the detected moving object is not less than 10cm x 20cm, and is used in the millimeter wave sensor transmission angle (the emission angle can be covered α is 15°, that is, the effective angle of the transmitting surface is 30°), and the distance (the center distance of the millimeter wave sensor antenna is from the center of the scanning target in the L range of 15cm-35cm, and the tolerance ±2cm) is shown in the figure below .Imaging-Healthcare-mm-100-Millimeter-Wave-Sensor-

WARNING: Do not modify this equipment without the authorization of the manufacturer.
WARNING: Do not replace the components without permission. If any part needs to be replaced, contact UIH Customer Service Center.

Use Case
Millimeter wave radar sensor can emit electromagnetic waves and receive reflected signals from the patient’s body surface. The reflected signals provide information about patient respiratory movement, which can be used in MRI respiratory triggering scan.
