Feasibility and Effectiveness of Respiratory Movement Management in Lung Cancer Receiving Stereotactic Radiotherapy Using a Novel Positional Fixation Device (E20241186)

April 24, 2026 updated by: Tianjin Medical University Cancer Institute and Hospital

A Single Center, Translational Study on the Feasibility and Effectiveness of Respiratory Movement Management in Lung Cancer Patients Receiving Stereotactic Radiotherapy Using a Novel Positional Fixation Device

The purpose of this clinical trial is to understand the safety and effectiveness of abdominal pressure devices in inhibiting respiratory movement in lung cancer patients. The main question it aims to answer is:

Did the abdominal pressure device reduce the respiratory movement of participants with lung cancer tumors?

Participants will:

Record how much they use abdominal pressure devices to suppress lung cancer tumor respiratory movement

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Breathing management group
CT/4DCT scan under breathing management
Device: Chest and abdominal compression
Abdominal compression suppresses respiratory movement in patients
Device: breathing management
Apply pressure to the patient's abdomen to achieve respiratory movement inhibition
No breathing management group
CT/4DCT scan under free breathing
