Seminario F. Di Franco

Il giorno 12 novembre alle ore 10, presso l'aula 300 Francesca Di Franco (INFN and univ. of Naples Federico II)

terra' un seminario dal titolo:

3D printed physical breast phantoms for X-ray breast imaging

Abstract

The growth of 3D printing technologies in the last years has been very rapid. 3D printing is an innovative technique for fabricating a wide range of different objects starting from 3D models. Novel materials and new printing techniques are being developed, so new applications are emerging. The medical physics team of the University of Naples Federico II have recently started a project for virtual clinical trials in 2D and 3D X-ray breast imaging starting from digital breast phantoms. An aspect of this project consist of manufacturing physical versions of digital phantoms using 3D printers. Many 3D printing technologies exist today: we use the common Fused Deposition Modelling (FDM), a technique where a thermoplastic material is first melted and after extruded onto a support plate in order to create the individual layer of the model. Patient-like 3D physical phantoms are needed to produce a realistic tissue background pattern in the images, important for the investigation of the detectability of lesions, in the dose estimations procedures, in the assessment of the performance of image processing algorithms and reconstruction algorithms.
