StereoCheck is designed to compute target coordinates using several stereotactic frames and models. It is an independent verification tool. This can be used along with the main planning system, This helps avoid human errors. It is an application for iPhone or iPad. It supports FiMe, Bramsys, Leksell, CRW and ZD frames. It could be used for Micromar frame too, configuring the app for a FiMe frame using “Symetric 140 mm” model. StereoCheck uses an algorithm which corrects tilted and/or rotated images with rotation up to 5 degrees, as long as nine fiducials are present in the image. StereoCheck is a verification tool and should not be used as the primary planning or computation system.
