[Formation of panoramic tomographic images]

Area of Science:

• Radiological imaging
• Medical physics
• Tomography

Context:

• Panoramic tomographic imaging is widely used in dentistry and medicine.
• Image quality is often limited by blurring of structures outside the focal plane.
• Accurate quantification of blurring is essential for diagnostic interpretation.

Purpose:

• To derive analytical expressions for quantifying the extent of blurring.
• To determine the blurring of points located beyond the isolated surface in panoramic tomograms.
• To provide a mathematical framework for understanding image formation limitations.

Summary:

• Analytical expressions were derived based on the principles of panoramic tomographic image formation.
• These expressions specifically address the blurring of points situated outside the defined focal surface.
• Experimental verification demonstrated the sufficient accuracy of the derived analytical expressions.

Impact:

• Enables more precise assessment of image quality in panoramic tomography.
• Facilitates the development of improved imaging techniques and algorithms.
• Contributes to enhanced diagnostic accuracy by accounting for image blur.
