Patients reported greater neck and shoulder comfort (p<0.020) and overall satisfaction (p<0.026) during CT simulation…Open masks with [customized head rest] provide comparable yet comfortable immobilization to closed masks with [standard head rest], for HN radiotherapy5

In head and neck cancer cases, Postural reproducibility deteriorates due to the non-rigidity of H&N…image-guided corrections cannot completely compensate for this 6

The inter-fractional patient setup accuracy was significantly better using AlignRT compared to laser alignment with skin marks. Reducing the frequency of CBCT scans reduces imaging dose and overall treatment time.7
