We present the design and preliminary imaging evaluation of an X-ray cone-beam breast computed tomography (CBBCT) apparatus, assembled for laboratory test of various optimization techniques for clinical CBBCT. The prototype is characterized by the computer-control of X-ray tube (35–80 kVp, 0.25 mA), CsI:Tl flat panel detector (12×12 cm2 area, 50 μm pitch), translation and rotation stages with eight degrees of freedom, fan-beam or cone-beam FDK backprojection. First tomographic images, obtained by rotating 14-cm diameter PMMA breast phantoms are presented.

Abstract
We present the design and preliminary imaging evaluation of an X-ray cone-beam breast computed tomography (CBBCT) apparatus, assembled for laboratory test of various optimization techniques for clinical CBBCT. The prototype is characterized by the computer-control of X-ray tube (35–80 kVp, 0.25 mA), CsI:Tl flat panel detector (12×12 cm2 area, 50 μm pitch), translation and rotation stages with eight degrees of freedom, fan-beam or cone-beam FDK backprojection. First tomographic images, obtained by rotating 14-cm diameter PMMA breast phantoms are presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
