The innovative comput- erized orientation process could improve precision and patient safety in a wide range of minimally invasive procedures, particularly spine surgery and neuro- surgery, write the Johns Hopkins University engineers in a recent issue of the journal Physics in Medicine and Biology. Setting up a conventional image-guidance system for use during sur- gery necessitates a laborious process known as registration, the corre- spondence of points on a patient's body to those appearing in a pre-op CT image that lets the system orient its images. "The registration process can be error-prone, require multiple manu- al attempts to achieve high accuracy and tends to degrade over the course of the operation," says Jeffrey Siewerdsen, PhD, a professor of biomedical engineering at Johns Hopkins.
