BAT
B-Mode Acquisition and Targeting
For additional information, see article.
BAT (B-mode Acquisition and Targeting) is an ultrasound-based targeting system used with external beam radiation to localize targets that may move from one treatment day to the next. Improved localization results in more accurate treatment. The process involves localizing the target, and associated organs, daily at the time of treatment. The BAT ultrasound probe is coupled to a position sensing device used to indicate the location and orientation of the probe relative to the treatment machine.
The target position is compared to the position of the target at the time of planning; and the patient position can then be adjusted so the target is in the originally planned position. BAT is appropriate for any organ that can be visualized by ultrasound. Possible sites include: prostate, liver, bladder, kidney, pancreas, uterus and breast. Its ability to reduce planning margins may allow more successful delivery of greater radiation treatment dosage while decreasing the risk of complications associated with standard and escalated dose prescriptions.
