چکیده
Screen-film image receptors have been the standard detector used in conventional mammography. New developments in detector technology and computers are altering the landscape of mammography imaging. Full Field Digital Mammography (FFDM) offers the promise of revolutionizing the practice of mammography through its superior dose and contrast performance. Advanced applications made possible through digital imaging, such as automated computer-aided diagnosis, dualenergy and 3D tomosynthesis are expected to further improve diagnostic sensitivity and specificity. This primer describes the technical basis for current and future advances in mammographic detector technology. These include all of the following: • Lower dose • Improved image quality • Computer-aided diagnosis • Softcopy review and digital archiving • Tomosynthesis and other three-dimensional visualization techniques • Reduction in breast compression pressure

A practical target system for accelerator-based BNCT which may effectively double the dose rate.
A dose-limiting component of a proton accelerator-based source of epithermal neutrons is the neutron production target. Possible targets are lithium, producing high yield but having low melting point and thermal conductivity, and beryllium, presenting less engineering problems but a much smaller neutron yield. We propose that a hybrid Be-Li target would provide the best of both worlds, with the...
متن کاملComparison of Performances for Air-Standard Atkinson and Dual Combustion Cycles with Heat Transfer Considerations
There are heat losses during the cycle of real engine that are neglected in ideal air-standard analysis. In this paper, the effect of heat transfer on the net output work is shown and thermal efficiency of the air-standard Atkinson and the Dual combustion cycles are analyzed. Comparison of performances of the air-standard Atkinson and the Dual combustion cycles with heat transfer considerations...
متن کاملAnalytical investigation of the practical range and deflection of megavoltage electron beam in the water phantom with the presence of magnetic field
Introduction: Integrated radiation therapy - MRI systems are capable of delivering high doses to the target tissues near sensitive organs and achieve better therapeutic results; however, the Applied magnetic fields for imaging, can influence the charged path, change the penetration depth and deflect the particles, laterally, leading to dose distribution variations. Therefore, i...
متن کاملI-12: Objective Embryo Assessment Utility of Time-Lapse
Background Traditionally, embryo incubation and assessment daily has been under a light microscope, these observations are inevitably restricted to specific times and considering that the development of the embryo is a dynamic process, several critical stages in between observations may go unnoticed. For this reason, the new technologies, time lapse monitoring, have focused on the research for ...
متن کاملDevice considerations for development of conductance-based biosensors.
Design and fabrication of electronic biosensors based on field-effect-transistor (FET) devices require understanding of interactions between semiconductor surfaces and organic biomolecules. From this perspective, we review practical considerations for electronic biosensors with emphasis on molecular passivation effects on FET device characteristics upon immobilization of organic molecules and a...
