What does a beams eye view represent in radiation therapy?

A beams eye view represents a perspective that is end-on, as if viewing from the radiation source. This viewpoint allows dosimetrists and radiation therapists to visualize how the radiation beam enters the patient’s body, providing crucial information about the angles and positions of the beams with respect to the target and surrounding tissues. By understanding this perspective, professionals can effectively plan treatment to maximize dose delivery to the tumor while minimizing exposure to healthy tissues. This view helps in creating accurate treatment plans, as it simulates the path of radiation and enables better evaluation of how the beams will interact with various anatomical structures.
