Stereotactic brain surgery: a method for rapid and precise positioning of a target in the Todd-Wells stereotactic instrument.
We describe an improved method for positioning the head for stereotactic brain surgery of aneurysms. The method uses a mathematical calculation and requires some physical modifications in the Todd-Wells stereotactic apparatus. This procedure achieves (1) a reduction in the number of angiograms needed and (2) an increase in the speed and accuracy of positioning. The technique has been applied to operations on live dogs.
