Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Planning to receive radiation therapy to head and neck/brain, thorax, abdomen, or pelvis
If the patient will be receiving IV contrast on study: Adequate renal function as defined by a serum creatinine < 1.4, or, for patients with chronic kidney disease, a stable serum creatinine < 2.0

No Placebo-Only Group

Summary

This trial is testing a new radiotherapy system called Halcyon 4.0 to see if it can quickly and safely capture images needed for planning cancer treatments. The goal is to improve the speed and safety of radiation therapy planning for cancer patients.

Who is the study for?
This trial is for adults over 18 who are set to receive radiation therapy for certain cancers (brain, head and neck, lung, stomach, colon) and can consent to the study. Women must not be pregnant. If IV contrast is used in the study, participants need normal or stable kidney function.
What is being tested?
The Halcyon 4.0 system's ability to create quality images for radiation treatment planning is being tested. This new technology aims to reduce image acquisition time and patient exposure to radiation during scans.
What are the potential side effects?
Since this trial focuses on imaging rather than a drug or therapeutic intervention, side effects are related mainly to potential discomfort from lying still during imaging or reactions if IV contrast is used.

Experimental Treatment
Group I: Halcyon 4.0 imagingExperimental Treatment1 Intervention
Patients planning to receive radiation therapy to the head and neck/brain, thorax, abdomen, or pelvis will undergo imaging on the Halcyon 4.0 system. Patients will return for a minimum of 2 sessions over 9 weeks, with a cumulative total of 10 images being collected.

Other Research
Radiotherapy, a common treatment for lung cancer, uses high-energy radiation to damage the DNA of cancer cells, preventing them from replicating and causing cell death. This precision is crucial for lung cancer patients as it targets tumors while sparing healthy tissue. Advances like the Halcyon 4.0 Radiotherapy System, which offers improved imaging and reduced radiation exposure, enhance treatment accuracy and safety, potentially improving patient outcomes and reducing side effects.
