12 Mammography

Mammography imaging

Requirements	Images require a wide exposure latitude and sharp definition
Imaging Plate	Structure • Differs from a conventional imaging plate by having a transparent support layer • Capable of 50 μm resolution imaging • 10 pixels/mm at standard pixel density and 20 pixels/mm at high pixel density • 18 × 24 cm and 24 × 30 cm format Fig. 12.1 Mammography imaging plate.
Image Acquisition	Structure • Specialist imaging plate • Laser scanner • Reflecting mirror • 2 light guides • 2 photosensors • Enables fast display time Fig. 12.2 Fujifilm^TM dual-side reading system.
Fujifilm Pattern Enhancement Processing (PEM)	Software • For mammography • Enables clearer identification of tumours • Enhances microcalcification making it more conspicuous
Kodak Mammography Total Quality Tool (Test Phantom)	Software • Analyses reporting software • Predicts common causes of failure • Storage of image test information
