A CT scanner includes a gantry, a handle, and a sensor located on or connected to the handle. During operation of the CT scanner, a control provides a signal to a motor to rotate the gantry about an axis of rotation. When the CT scanner is not taking a CT scan, a locking mechanism locks the gantry to prevent rotation of the gantry. When the sensor detects an operator, the control provides a signal to disengage the locking mechanism, allowing the gantry to freely rotate about the axis of rotation. When the sensor no longer detects the operator, the control sends a signal to lock the locking mechanism and lock the gantry in the current position.
