digital tomosynthesis

digital tomosynthesis

a system of tomography, using a computer and a digital fluoroscopy unit, that can synthesize any tomographic plane from a single tomographic pass. As only one tomographic pass is required, patient radiation exposure is reduced. Patient time in examination is also reduced as the recorded images can be synthesized and manipulated at a later time. See also digital fluoroscopy.

Furthermore, all of the applications are built to serve across both full-field digital mammography and digital tomosynthesis systems, and with multi-vendor compatibility and reproducible data," said Frost & Sullivan Research Director, Advanced Medical Technologies Group, Siddharth Saha.
The topics are digital tomosynthesis, ultrasound elastrography, quantitative imaging biomarkers of cancer, medical imaging informatics, medical physics criteria for performance excellence, quality control in mammography, programs in place to protect the public from unnecessary radiation exposure from x-ray sources, and a primer for medical and public health practitioners on medical response to a major radiological emergency.
Many unique acquisition capabilities, such as dual-energy image tissue decomposition and limited-angle digital tomosynthesis, are important when considering future applications of specific importance.
The data set was derived from a study in which 1,083 women, age 18 years or more, underwent two-view, full-field digital mammogram (FFDM) and digital tomosynthesis exams at five U.
Early indications have suggested that digital tomosynthesis may reduce the selection of patients for biopsy, improve cancer detection rates [20] and reduce recall rates [20,21].
The primary target application for the new sensor is X-ray medical imaging and more specifically mammography and digital tomosynthesis, the advanced diagnostic technique used to generate 3D representations of patients or other scanned objects.
Digital tomosynthesis is a new technology with improved diagnostic capabilities over standard digital mammography.
Digital tomosynthesis can bring 3-dimensional imaging to DR.
And a technique known as digital tomosynthesis may allow users to take nine low-radiation-dose mammograms from different angles--which together amount to the radiation exposure of a single conventional mammogram--and combine them electronically so that three-dimensional surface characteristics of lesions can be analyzed.
The study also discusses technology trends like Digital Tomosynthesis and trends in other imaging modalities such as Breast MRI, Breast Ultrasound .
VolumeRAD - GE's version of digital tomosynthesis for radiography removes overlaying and underlying structures, which improves the detection of lesions and therefore enhances sensitivity.
