Description
When used without a face mask, the DSPS-Prominent® provides a therapist-friendly, patient-centered approach for head & neck positioning using only a posterior shell supported by surface-guided radiotherapy (SGRT). By removing the top mask, therapists can offer treatments that are more comfortable and less anxiety-inducing for patients, while maintaining confidence in reproducible setups.
This approach is particularly helpful for patients who are claustrophobic, have mask intolerance, or require special accommodations. Despite the absence of a top mask, DSPS‑Prominent® maintains submillimeter reproducibility and high setup stability, comparable to traditional full-mask setups. Clinical data demonstrates minimal intrafraction motion and few interruptions, allowing therapists to consistently meet precise PTV margins and reduce time spent on repositioning.
From a workflow perspective, the maskless setup simplifies daily patient positioning and reduces the complexity of set-up, while optical surface guidance serves as a continuous backup. This empowers therapists to focus on accuracy, efficiency, and patient comfort simultaneously.
