A method, system and software are presented for making a trackable mount (10, 11, 12) for assisting with surgery within a surgical site, the trackable mount being trackable by a tracker disposed to obtain image information of the surgical site. A software model of the trackable mount is created based on scan data (510) of the surgical site, and the making of the trackable mount is based on model data (550) derived from the software model. The exterior shape of the trackable mount may incorporate a tracking marker (12, 12'), or tracking pole (11, 11'), or both. A system (500) for executing the method consists of scan data of the surgical site, a controller (520) with memory (540) and processor (530), and a manufacturing device (570). In one embodiment the manufacturing device is a rapid prototyping machine. Software (560) is presented for executing the method of embodiments of the invention.
