Abstract EN
Flat panel detector-based cone beam breast CT (CBBCT) can provide 3D image of the scanned breast with 3D isotropic spatial resolution, overcoming the disadvantage of the structure superimposition associated with X-ray projection mammography.
It is very difficult for Mammography to detect a small carcinoma (a few millimeters in size) when the tumor is occult or in dense breast.
CBBCT featured with circular scan might be the most desirable mode in breast imaging due to its simple geometrical configuration and potential applications in functional imaging.
An inherited large cone angle in CBBCT, however, will yield artifacts in the reconstruction images when only a single circular scan is employed.
These artifacts usually manifest themselves as density drop and object geometrical distortion that are more noticeable in the reconstructed image areas that are further away from the circular scanning plane.
In order to combat this drawback, a circle plus partial helical scan scheme is proposed.
An exact circle plus straight line scan scheme is also conducted in computer simulation for the purpose of comparison.
Computer simulations using a numerical breast phantom demonstrated the practical feasibility of this new scheme and correction to those artifacts to a certain degree.
