Method and system for automatic intra-oral sensor locating for image acquisition
A method and systems for capturing digital intra-oral images, while automatically determining a location of an intra-oral sensor placed within a mouth of a patient, is disclosed. A spatial frame-of-reference is established with respect to teeth within the mouth of the patient. An intra-oral digital imaging sensor is placed within the mouth of the patient adjacent to at least one tooth within the mouth that is to be imaged using the intra-oral sensor. Spatial location information is automatically generated such that the spatial location information defines how the intra-oral sensor is placed with respect to the spatial frame-of-reference. A digital image of at least one tooth is acquired using the intra-oral sensor and the spatial location information is automatically associated with the acquired digital image. The associated spatial location information may be used to automatically correlate the acquired image to a tooth or teeth within the mouth and/or to automatically orient the acquired image for display.
1. A method of capturing intra-oral digital images, said method comprising:
establishing an internal spatial frame-of-reference with respect to teeth within a mouth of a patient;
placing an intra-oral digital imaging sensor within said mouth of said patient adjacent to at least one tooth within said mouth that is to be imaged using said intra-oral sensor, wherein said intra-oral sensor is not physically connected to said spatial frame of reference;
automatically generating first spatial location information defining how said intra-oral sensor is placed with respect to said spatial frame-of-reference;
acquiring a first digital image of said at least one tooth using said intra-oral sensor;
automatically associating said first spatial location information with said first digital image;
automatically associating said first digital image with one of a plurality of pre-defined areas in a tooth chart corresponding to said associated first spatial location information;
automatically orienting said first digital image to said one associated pre-defined area of said tooth chart in response to said first spatial location information or a default or pre-defined user preference of image orientation for said one associated pre-defined area of said tooth chart; and
displaying said tooth chart and said oriented first digital image in said one associated area of said tooth chart.
