Abstract
An example computer-implemented method for tuning a beam spot in a radiation therapy system has been disclosed. The example method includes configuring an electron beam to generate a first beam spot on an electron-beam target of the radiation therapy system, generating, using an imager of the radiation therapy system, a first plurality of projection images of the first beam spot, wherein each of the projection images of the first beam spot is generated with a line of sight blocked between the imager and a different respective portion of the beam spot, based on the first plurality of projection images, determining a value for one or more beam spot quality metrics associated with the first beam spot, and based on the value, determining whether the first beam spot is outside a specified quality range.
