System and Method for Low Dose Tomosynthesis |
摘要 |
A breast imaging system leverages the combined strengths of two-dimensional and three-dimensional imaging to provide a breast cancer screening with improved sensitivity, specificity and patient dosing. A tomosynthesis system supports the acquisition of three-dimensional images at a dosage lower than that used to acquire a two-dimensional image. The low-dose three-dimensional image may be used for mass detection, while the two-dimensional image may be used for calcification detection. Obtaining tomosynthesis data at low dose provides a number of advantages in addition to mass detection including the reduction in scan time and wear and tear on the x-ray tube. Such an arrangement provides a breast cancer screening system with high sensitivity and specificity and reduced patient dosing. |

1. A method of imaging a breast using a multi-mode mammography/tomosynthesis system, the method comprising:
acquiring a two-dimensional image of a breast using a first x-ray dose in a first mode of operation of the multi-mode mammography/tomosynthesis system; acquiring a set of tomosynthesis images of the breast in a second mode of operation of the multi-mode mammography/tomosynthesis system, wherein the set of tomosynthesis images is acquired at a second x-ray dose less than or equal to the first x-ray dose. |
