Abstract
An array of sensors may be used to perform touchless registration of landmarks of a patient's face before an ENT procedure in order to associate those landmarks with pre-operative images in three-dimensional space, which is required for image guided surgery features such as navigation. Touchless or light-touch registration may improve accuracy by avoiding the need for substantial pressing against a patient's skin, which may deform and thereby introduce erroneous registration data. A sensor may also be implemented in forms other than an array such as handheld probe having a single sensor as opposed to an array.
