Abstract
A 2D mammogram image is synthesized from at least one of tomosynthesis projection images and/or the tomosynthesis reconstructed image data. In a simplest form, the mammogram may be synthesized by selecting one of the tomosynthesis projection images for display as a synthesized mammogram. Other methods of synthesizing a mammogram include re-projecting and filtering projection data and/or reconstructed data. The synthesized mammogram is advantageously displayed together with at least a portion of the reconstructed data to aid in review of the reconstructed data. The present invention thus provides a familiar image which may be used to facilitate review of a tomosynthesis data set.
Claims21
(canceled)
A system for generating and displaying a synthesized mammogram, the system comprising:
- a computer system, including
- a reconstruction engine configured to receive a tomosynthesis data set, the tomosynthesis data set comprising one or more of a plurality of tomosynthesis projection images and/or one or more of a plurality of tomosynthesis reconstructed slices of a patient's breast, and
- a synthesizer configured to generate a two-dimensional synthesized mammogram from only the tomosynthesis data set, wherein the synthesized mammogram comprises a synthesized two-dimensional image of an entirety of a patient's breast that simulates a conventional mammography image;
- and
- a display device operatively coupled with the computer system, wherein the computer system is configured to cause the display device to independently or simultaneously display one or more images from the tomosynthesis data set and the synthesized mammogram.
A computer-implemented method for generating and displaying a synthesized mammogram, the method comprising:
- receiving a tomosynthesis data set comprising one or more of a plurality of tomosynthesis projection images and/or one or more of a plurality of tomosynthesis reconstructed slices of a patient's breast;
- generating a two-dimensional synthesized mammogram from only the tomosynthesis data set, wherein the synthesized mammogram comprises a synthesized two-dimensional image of an entirety of a patient's breast that simulates a conventional mammography image, and
- independently or simultaneously displaying one or more images from the tomosynthesis data set and the synthesized mammogram.
