Physica Medica, pp. 1-12. 4 Zackrisson S, Lång K, Rosso A, Johnson K, Dustler M, Förnvik D et al. Here, we share a curated dataset of digital breast tomosynthesis images that includes normal, actionable, biopsy-proven benign, and biopsy-proven cancer cases. The dataset contains four components: (1) DICOM images, (2) a spreadsheet indicating which group each case belongs to (3) annotation boxes, and (4) I mage paths for patients/studies/views . 2021-04-23 · Tomosynthesis acquisition can be performed in both ST (Standard) and HR (High Resolution) modes, according to desired accuracy and lesion size.

Tomosynthesis allows radiologists to gain better visualization of the breast, which is the primary benefit of this new technology. Three-dimensional (3D) mammography (also called digital breast tomosynthesis, digital tomosynthesis, or just tomosynthesis) creates a 3D picture of the breast using X-rays.


The term ”tomosynthesis” merges ‘tomography’ and ‘synthesis’. It is a special type of imaging technology that fuses cone-beam CT reconstruction with digital image processing to produce images of specified cross-sections from a single tomography.

Tomosynthesis images

During the acquisition, any detector element receives in time sequence-related information on each object volume element. Tomosynthesis projection images are acquired over an angular range of 15 to 50 degrees. This angular range affects image quality in several ways. Wider angle acquisition reduces the amount of superimposed tissue that may be present in the reconstructed tomosynthesis images. 1 Compared to FFDM. Cancer detection rate was 43% higher for invasive cancers in a large prospective screen trial of 15,000 women. Zackrisson S, Lång K, Rosso A, Johnson K, Dustler M, Förnvik D et al.

Images in a 55-year-old woman with a spiculated mass localized in the upper central quadrant (arrow in A, B, D, and E) of right breast detected with digital breast tomosynthesis (DBT) plus synthetic mammography (SM). Breast density was classified as category C with the Breast Imaging Reporting and Data System. The SM images are created by summing and filtering the stack of reconstructed tomosynthesis sections, similar to generating a weighted maximum intensity projection image.

C-View 2D images also serve as a navigational aid to the tomosynthesis slice review. Published studies show that the low dose Genius™ 3D MAMMOGRAPHY™ exam finds invasive cancer This 8-minute webinar is presented by Dr. Andrew Smith, VP Image Science, Hologic. It covers the innovative technology behind C-View™ software including how C-View™ 2D images are created and used with breast tomosynthesis images as well as case examples. Provided by Hologic Return to Breast Health Education & Training Tomosynthesis captivated her interest and she has since investigated many aspects of tomosynthesis imaging, such as computer-aided detection, system modeling, and objective assessment. Her research interests further include image perception and observer performance, as well as tomosynthesis and CT image reconstruction. 2018-09-18 · Tomosynthesis can look at multiple layers of the breast in a 3-dimensional (3-D) image. This allows this method to fill in the gaps or limitations that traditional mammograms have, since a Breast tomosynthesis uses a low-dose x-ray system, electronics and a computer to convert x-ray images of the breast to a three-dimensional image set.
