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.
Claims18
A method for use in a computer system comprising one or more processors performing the steps of:
- obtaining a plurality of x-ray tomosynthesis projection images of a patient's breast;
- generating a three dimensional reconstruction of the patient's breast using the x-ray projection images;
- synthesizing a two-dimensional mammogram using at least a subset of the plurality of x-ray tomosynthesis projection images, including re-projecting at least a portion of the three dimensional reconstruction onto a two-dimensional image;
- and
- displaying the synthesized mammogram on a display device.
A system comprising:
- a processor coupled to a computer readable medium having program code stored thereon, the program code being operable when executed upon by the processor to synthesize an x-ray mammogram using only one or more x-ray tomosynthesis projection images;
- and
- a display device for displaying the synthesized mammogram wherein the program code for synthesizing the mammogram using the x-ray tomosynthesis projection images includes program code for generating a three dimensional reconstruction using the x-ray projection images, and wherein the program code for synthesizing the mammogram performs at least one of filtering and re-projecting of at least one of the x-ray tomosynthesis images and a portion of the three dimensional reconstruction to synthesize the mammogram.
A system comprising:
- a processor coupled to a computer readable medium having program code stored thereon, the program code being operable when executed upon by the processor to synthesize an x-ray mammogram using only one or more x-ray tomosynthesis projection images;
- and
- a display device for displaying the synthesized mammogram;
- and
- an image acquisition device for obtaining the x-ray tomosynthesis projection images, the image acquisition device comprising an x-ray source, a digital detector and a controller;
- wherein the program code is further operable when executed upon by the processor to reconstruct the tomosynthesis projection images into a three dimensional reconstructed image for synthesizing the mammogram and for generating a set of slabbed slices from the reconstructed image, re-projecting the set of slabbed slices to provide a two dimensional image and filtering the two dimensional image to provide the synthesized mammogram.
