Patent ID: 7827038

Claim:
A mask fitting system for selecting a mask system for a patient, the system comprising: at least one terminal configured to receive patient data specific to the patient, including at least one two-dimensional front image of the patient and at least one two-dimensional profile image, the patient data including a nasal or nares image of the patient; an input controller in communication with the at least one terminal, the input controller being configured to determine the patient's facial dimensions from the at least one two-dimensional front image and the at least one two-dimensional profile image via an automatic facial feature extractor or pointer-based input mechanism, the automatic facial feature extractor or pointer-based input mechanism being usable to identify predefined locations on the patient's face in deriving the facial dimensions of the patient; a mask system database to store mask system data relating to a plurality of mask systems; a communication channel by which the patient's facial dimensions are to be communicated with the mask system database; and at least one controller configured to compare the patient's facial dimensions with the mask system data stored in the mask system database, so as to select at least one best fit mask system from the plurality of mask systems for the patient, in dependence on the comparison.
