TY - JOUR T1 - Simplified CT-guided stereotaxic biopsy. JF - American Journal of Neuroradiology JO - Am. J. Neuroradiol.

A small, commercially available, programmable calculator is used to interrelate frame and CT section geometry. The system can be used with any CT scanner that can specify (x,y) coordinates of a pixel, obviating the need for extensive modifications of the CT computer software. Representative clinical cases are presented. ER -
