Generating a panoramic radiography image

An imaging device comprising:

• an x-ray source;
• an x-ray detector;
• a processor;
• a storage unit in communication with the processor and is configured to receive and store a plurality of radiography images of a body part of a patient captured along a predetermined panoramic trajectory using the imaging device;
• and
• a memory, in communication with the processor, with one or more computer program instructions stored on the memory, the computer program instructions, when executed by the processor, cause the imaging device to perform a plurality of operations including:
• retrieving at least one three-dimensional (3D) model of the body part of the patient from at least one data source;
• forming a panoramic radiography image of the body part of the patient from the plurality of radiography images;
• registering the 3D model with the panoramic radiography image;
• identifying one or more interference areas in the 3D model that are responsible for interference in the panoramic radiography image based on the predetermined panoramic trajectory;
• generating a plurality of virtual panoramic projection images for the one or more interference areas using the 3D model, the plurality of virtual panoramic projection images is generated using a geometry and a frame rate used to form the panoramic radiography image;
• and
• removing the one or more interference areas from the plurality of radiography images or the panoramic radiography image based on the plurality of virtual panoramic projection images.

A non-transitory computer-readable medium having instructions, which when executed by a processor of an imaging device, cause the imaging device to:

• capture a plurality of radiography images of a body part of a patient along a predetermined panoramic trajectory using an imaging device;
• retrieve at least one three-dimensional (3D) model of the body part of the patient from at least one data source;
• form a panoramic radiography image of the body part of the patient from the plurality of radiography images;
• register the 3D model with the panoramic radiography image;
• identify one or more interference areas in the 3D model that are responsible for interference in the panoramic radiography image based on the predetermined panoramic trajectory;
• generate a plurality of virtual panoramic projection images for the one or more interference areas using the 3D model, the plurality of virtual panoramic projection images is generated using a geometry and a frame rate used to form the panoramic radiography image;
• and
• remove the one or more interference areas from the plurality of radiography images or the panoramic radiography image based on the plurality of virtual panoramic projection images.
