The utility model provides coordinate-setting screen-aperture marking lead grids for an X-ray body surface projection matrix of a lung tumor. The coordinate-setting screen-aperture marking lead grids include a lead metal framework and a polyvinyl chloride film; the lead metal framework includes ...
This invisible stylus dubbed a Pixel Probe is created through the orthographic projection of a spherical mounted reflector (SMR) through a trifocal camera system. Through this, a single point in space that is linked to a laser tracker world frame is mapped to a unique set of pixel coordinates...
