Respiratory gating during 4DCT acquisition



GateCT offers a flexible solution to many of the challenges of 4DCT acquisition, using a single stereo camera unit which tracks the patient during CT acquisition. GateCT can be used to track a patient’s breathing during CT scanning and thereby enable 4DCT acquisition and reconstruction.

Benefits include:

  • Marker-less: No physical markers, box, belt or bellows needed, nor anything attached to the couch

  • Non-invasive and no ionizing radiation

  • Intuitive: Easy to correct phase tags and label breathing data, tracking data can be viewed offline
