A Study Evaluating a New Radiation Treatment Workflow (NGDS) (SPEED)

14. september 2026 oppdatert av: Varian, a Siemens Healthineers Company

A ProSPEctivE Study of NGDS DMAT Workflow Feasibility

The purpose of this research is to evaluate the "Next Generation Delivery System" (NGDS) and determine if this machine will be more efficient at delivering radiation in shorter treatment time and better patient tolerance, with less breath holding.

Detaljert beskrivelse

This study is a prospective multi-center clinical trial. It is designed to evaluate the feasibility of a breath hold workflow on a new treatment platform (NGDS DMAT).

Eligible participants will be receiving stereotactic body radiotherapy (SBRT) under breath hold conditions to targets in the thorax and upper abdomen as part of their routine care.

Enrolled participants will be asked to undergo a mock treatment on this new treatment platform under breath hold conditions. Participant images for set up and alignment will be obtained on the NGDS.

Tidsramme
To evaluate the feasibility of the mock NGDS DMAT workflow under breath hold conditions.
Tidsramme: From enrollment to end of "mock" treatment of last participant enrolled, assessed up to 6 months

Feasibility of the mock NGDS DMAT treatment workflow under breath hold conditions will be confirmed following successful execution of each step:

  1. Acquisition of an IDENTIFY-monitored breath hold kV HyperSight CBCT
  2. Conduct verification imaging of shifts and breath hold position using kV fluoroscopy
  3. Delivery of an investigator approved "mock" DMAT treatment plan
From enrollment to end of "mock" treatment of last participant enrolled, assessed up to 6 months

To assess patient-specific quality assurance results for DMAT plans.
Tidsramme: From enrollment to end of "mock" treatment of last participant enrolled, assessed up to 6 months
Delivery quality assurance and dose calculation accuracy will be measured by institutional-specific QA equipment (compliant with AAPM (American Association of Physicists in Medicine) Task Group 218).
