A method of identifying a particular mask for a patient for use in delivering a flow of breathing gas to the patient is carried out by first receiving a 2-D frontal image of the patient. Next, 3-D facial information of the patient is determined from the 2-D frontal image. At least some of the 3-D facial information is compared with dimensional information of a plurality of candidate masks. Finally, the particular mask for the patient is determined from a result of the comparison of the at least some of the 3-D facial information and the dimensional information of the plurality of candidate masks.
