SUPER-RESOLUTION TOMOSYNTHESIS IMAGING SYSTEMS AND METHODS

摘要

Tomosynthesis imaging methods, systems, and apparatus are disclosed. The systems may include a source to emit penetrating particles toward an object, a detector to acquire a series of projection images responsive to the penetrating particles, and a positioning system to position the source relative to the object and the detector. An imaging system controls the positioning apparatus, source, and detector to acquire images along a primary scan direction with offsets in a secondary scan direction. An oscillatory motion may be applied to the source to reduce focal spot blur. Tomographic volumes are constructed that are capable of exhibiting super-resolution from data representing the acquired series of projection images taking the primary scan direction and the offsets into consideration.
