The American Society for Radiation Oncology (ASTRO) issued a new clinical guideline for the use of stereotactic body radiation therapy (SBRT) in early-stage lung cancer today. While SBRT is the current standard of care for peripherally located tumors in patients who cannot undergo surgery, the new guideline addresses the appropriateness of SBRT for medically inoperable patients with high-risk clinical scenarios requiring curative focused therapy. 

As radiation therapy continues to evolve, new techniques and technologies are largely focused on maximizing the dose to the tumor site while protecting surrounding tissue as much as possible. Image guidance is a critical component of treatment planning for tumor delineation and gauging treatment response, and cone beam computed tomography (CBCT) has traditionally been the modality of choice.
