Estimation of scattered radiation in digital breast tomosynthesis

Estimation of scattered radiation in digital breast

13 Digital breast tomosynthesis (DBT) is a promising technique to overcome the tissue 14 superposition limitations found in planar 2D X-ray mammography. However, as most 15 DBT systems do not employ an anti-scatter grid, the levels of scattered radiation 16 recorded within the image receptor are significantly higher than that observed in planar 17 2D X-ray mammography. Knowledge of this field i...

Radiation dosimetry in digital breast tomosynthesis: report of AAPM Tomosynthesis Subcommittee Task Group 223.

The radiation dose involved in any medical imaging modality that uses ionizing radiation needs to be well understood by the medical physics and clinical community. This is especially true of screening modalities. Digital breast tomosynthesis (DBT) has recently been introduced into the clinic and is being used for screening for breast cancer in the general population. Therefore, it is important ...

Digital Breast Tomosynthesis (DBT)

DBT is a three-dimensional (3D) breast imaging technology that uses a rotating X-ray source to acquire multiple image slices at several angles. The X-ray source rotates around the breast in an arc. Serial exposures are taken every few degrees in the arc rotation. These images are then reconstituted by software to produce a 3Dimage of the breast, similar to CAT scanning. It has been suggested th...
