    The design, construction and testing of a hermetically sealed breast platfrom for dual-modality mammography
    (2014) Smith, Raphael V; Vaughan, Christopher Leonard (Kit)
    When ultrasound is used as an adjunct to X-ray mammography in either hand-held or automated mode, the patient typically lies in a prone position. The disadvantages of this approach include: variable image quality; poor co-registration of X-ray and ultrasound images; and increased costs and patient anxiety. In response to these shortcomings, the Aceso full-field digital mammography and automated breast ultrasound (FFDM+ABUS) system aims to acquire both X-ray and 3D ultrasound images simultaneously. The Aceso has been developed by the Cape Town based company CapeRay Medical (Pty) Ltd. The focus of this thesis is the design, construction and testing of a novel breast platform wherein the challenges of combining FFDM and ABUS have been addressed, in a clinically suitable package.
