A photon-counting detector for dual-energy breast tomosynthesis free
May 01, 2011 A multislit photoncounting tomosynthesis system was utilized (spectral imaging) to produce both low and highenergy tomographic data (below and above the k edge of iodine, respectively) in a single scan, which allowed for dualenergy visualization of iodine.
Mar 13, 2009 We present the first evaluation of a recently developed siliconstrip detector for photoncounting dualenergy breast tomosynthesis. The detector is well suited for tomosynthesis with high dose efficiency and intrinsic scatter rejection.

Optimization of a dualenergy contrastenhanced technique for a photoncounting digital breast tomosynthesis system: I. A theoretical model AnnKatherine Carton, Christer Ullberg, Karin Lindman, Raymond Acciavatti, Tom Francke, and Andrew D. A.
We have developed a dualenergy subtraction technique for contrastenhanced breast tomosynthesis. The imaging system consists of 48 photoncounting linear detectors which are precisely aligned with the focal spot of the xray source.
Purpose: Previously, the authors developed a dualenergy (DE) acquisition technique for a photoncounting digital breast tomosynthesis (DBT) imaging system. Lowenergy (LE) and highenergy (HE) images are acquired in a single scan by covering alternate slits of a multislit prepatient collimator with Sn and Cu, respectively.
