Abstract
A first laser device and a second laser device direct a laser beam towards a patient before a CT scan to visually indicate an outer boundary of an area where x-rays will be directed during the CT scan. Each laser device includes a prism that deflects the laser beams to form lines on the patient that define an outer boundary of an area of the patient that will be exposed to the x-rays. If the area of the patient between the lines is not the desired area, the operator can move the patient until the desired area of the patient is located between the lines. A third laser device can direct a laser beam to define an outer boundary that is used to ensure proper orientation of the patient in the space.
