Abstract
The IORT system includes a moveable cart, a robot arm assembly coupled to the cart, at least one applicator fixed relative to a patient, a treatment head coupled to the robot arm assembly for selective alignment with the applicator in a soft-docking procedure, and a haptic control assembly on the treatment head. A plurality of arm members is pivotally coupled to each other to provide at least five axes of movement for increased positioning flexibility and the enhanced flexibility increases the reach of the treatment head for accurate alignment. The alignment follows a two-stage process with a coarse alignment performed by the haptic control assembly to position a sensor array on the treatment head within detection range of an endcap on the applicator. Final alignment is autonomous employing range data from the sensor array to accurately position the treatment head with respect to the applicator.
