We have developed a digital radiography system based on double sided mi-crostrip silicon crystals. The detector is 300 m thick, equipped with 320 channels for each side. The strip pitch is 100 m. The read{out system consists of a VLSI integrated analog circuit with low noise preampliication, pulse shaping, threshold discrimination. The two main issues of this Front End chip are low noise and go...
AIM The combination of different imaging modalities through the use of fusion devices promises significant diagnostic improvement for breast pathology. The aim of this study was to evaluate image quality and clinical feasibility of a prototype fusion device (fusion prototype) constructed from a standard tomosynthesis mammography unit and a standard 3D ultrasound probe using a new method of brea...

The Digital Database for Screening Mammography (DDSM) is an invaluable resource for digital mammography research. However, there are two particular shortcomings that can pose a significant barrier to many of those who may want to use the resource: 1) the actual mammographic image data is encoded using a non-standard lossless variant of the JPEG image format; 2) although detailed metadata is pro...
