Read the full statement (118 words)

This product is to be used by radiation therapy oncologist or staff under their direction to

locate the position relative to the patient of the isocenter of a treatment beam on a gantry

mounted radiation therapy treatment machine. Some internal or external marker must be

visible on both a radiograph of the patient taken at the time of treatment and the images

used for the treatment plan in order to use this software to align the marker image on the

radiograph with the plan to find the proper patient support system coordinates. Only a

translation along the couch lateral, longitudinal, and height directions are considered and

solved for. Possible rotations or repositioning of the patient are not considered.

Indications for use as stated in the FDA summary.
