I looked through the VisionRT training documents and I found a troubleshooting document that indicated that my issue can be resolved by expanding the ROI to include both breasts and even expanding the SCV section of the ROI. My question now is, has anyone out there tried this and did it affect the breath hold level accuracy (e.g. determined from the kV LAT image)?
