Elekta, Norcross, Ga, offers PrecisePLAN?. This system utilizes an aperture-based inverse planning technique, which creates geometric or dosimetric field segments that conform to the planning target volume (PTV), while shielding the healthy organs. This IMRT technique offers several advantages: standard protocols using a work-flow manager, no delivery compromises introduced by the fluence interpreter software, better monitor unit efficiency, and simple statement of dose objectives. In addition, the aperture-based approach produces intuitive and sensible segments, greatly simplifying the IMRT verification process. (770) 300-9725 ext 145; www.elekta.com .
