The Neuroparallelogram, a radiographic system with an opposing tube-serial film changer provides for isoentric 2:1 magnification, stero radiography, a.p. or p.a. projections, more accurately positioned bi-plane angiography and the capacity for angiotomography. Angiographic examinations are expedited not only by the ease of set-up for different projections, but also by the capacity to accommodate for head rotation without repositioning the patient. The tube and film changer can be uncoupled so that routine films may be obtained. The improved detail of magnification radiography and the simplicity of positioning can also be used to perform routine skull radiography.
