  • Multi-leaf collimator based field size clipping for automatic adaptation to allowed image area
    Patent number: 7564950
    Abstract: A system and method for capturing a portal image using a linear accelerator having a multi-leaf collimator (MLC) and an imager allows the portal image field to be automatically clipped using the multi-leaf collimator so that the projection of the portal image field onto the imager falls within the allowed image area of the imager. In this manner, portal images may be obtained in instances where the projection of the portal image field onto the flat-panel imager is larger than an allowed image area of the imager, or where the projection of the portal image field onto the imager is not centered and would extend beyond the allowed image area, so that radiation sensitive electronics outside of the allowed image area are protected from undesirable exposure to radiation.
