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

Inclusion Criteria:

Clinical diagnosis is solitary peripheral lung cancer, and after comprehensive evaluation by the participating physicians based on the patient's clinical data, it is suitable for receiving SBRT treatment;

Exclusion Criteria:

Central or super central lung cancer patients who are intolerant or unwilling to undergo respiratory suppression and chest and abdominal compression fixation

This trial will enroll 50 patients with NSCLC scheduled to receive SBRT
