Abstract
The diagnostic yield of computed tomography (CT)-guided biopsies is dependent on accurate
needle insertion. A laser-assisted angle selection system was custom fabricated and
used during a CT-guided lung biopsy. Off-target error was measured comparing standard
methods to the laser method while pointing towards the target from the skin. The difference
between the planned angle and selected angle using the laser-assisted system was 2°,
improved from 12° with the standard method. Although yet to be confirmed, laser-assisted
angle selection systems may improve the accuracy of needle placement, which may translate
into improved outcomes for certain needle based procedures.
