Research from Washington University School of Medicine in St. Louis has found using new mmWave technology to be a great asset to perform precise monitoring of patient motion in real-time during radiotherapy treatments. The mmWave technology can monitor displacements with .1mm to 1 mm accuracy at low cost using a simple and easy to use device. Imaging with millimeter waves can overcome obstacles of current techniques like the optical tracking of a patient’s skin surface or CT scanning. This new device can also monitor breathing and cardiac motion that may, in time, replace respirometers or other breathing monitoring devices.
