Because the data acquired is incomplete, tomosynthesis is unable to offer the extremely narrow slice widths that CT offers. However, higher resolution detectors can be used, allowing very-high in-plane resolution, even if the Z-axis resolution is poor. The primary interest in tomosynthesis is in breast imaging, as an extension to , where it may offer better detection rates with little extra increase in radiation exposure.
We are committed to providing quality medical care using research-based practice for treatment of critical illnesses and conditions. Our advanced treatments include- Cyberknife, PET CT Scan, Digital mammography with Tomosynthesis.
Tomosynthesis, the latest in digital mammography, is a form of 3D mammography that works by using 3D technology to capture multiple images of the breast from different angles. Unlike conventional mammography, which produces a flat image, tomosynthesis produces a more detailed, multi-layered image of the breast tissue.
Tomosynthesis detects cancer up to 15 months earlier than traditional mammograms, reduces the risk of false positives and detects 41 percent more invasive breast cancers.*
Volpara Solutions Limited is the wholly-owned sales and marketing arm of Volpara Health Technologies Limited – an ISO13485 and ISO27001 certified, ISO14971, FDA GMP compliant research, development and manufacturing company that develops digital health solutions to enable personalized, high-quality breast cancer screening based on objective measurements of breast density, compression and radiation dose.
Mammograms are a tool used to detect and diagnose breast cancer. At Gwinnett Medical Center, we’ve taken early detection to a new dimension with breast tomosynthesis.
Digital tomosynthesis combines digital image capture and processing with simple tube/detector motion as used in conventional radiographic tomography. Although there are some similarities to CT, it is a separate technique. In CT, the source/detector makes a complete 360-degree rotation about the subject obtaining a complete set of data from which images may be reconstructed. In digital tomosynthesis, only a small rotation angle (e.g., 40 degrees) with a small number of discrete exposures (e.g., 10) are used. This incomplete set of data can be digitally processed to yield images similar to conventional tomography with a limited . However, because the image processing is digital, a series of slices at different depths and with different thicknesses can be reconstructed from the same acquisition, saving both time and radiation exposure.
