Abstract
There is provided a method of analyzing a plurality of views of an object, the object including an edge portion partially extending from a surface of the object into an internal volume of the object, comprising the step of analyzing each acquired view. The step of analyzing each acquired view includes analysis of the edge portion. Preferably, the object comprises breast tissue.
Claims44
A method of analyzing a plurality of views of an object, said object including an edge portion partially extending from a surface of said object into an internal volume of said object, comprising the step of:
- analyzing each acquired view,
- wherein the step of analyzing each acquired view includes analysis of said edge portion.
A program product for causing a machine to analyze a plurality of views from a tomosynthesis system, said tomosynthesis system imaging an object including an edge portion partially extending from a surface of said object into an internal volume of said object, said program product causing the machine to perform the step of:
- analyzing each acquired view,
- wherein the step of analyzing each acquired view includes analysis of said edge portion.
A tissue imaging device, comprising:
- a radiation source for emitting radiation through tissue to be imaged, said radiation source being angularly displaceable through a plurality of emission positions corresponding to a plurality of views;
- a detector positioned to detect radiation emitted through said tissue, said detector generating a signal representing a view of said tissue;
- and
- a processor electrically coupled to said detector for analyzing said signal,
- wherein said processor analyzes at least one of said plurality of views, said analysis including analysis of an edge portion of said tissue partially extending from a surface of said tissue into an internal volume of said tissue.
A method of analyzing an object with a multi-modality imaging system, comprising the steps of:
- detecting a region of concern in at least one of a first image of said object generated by a first modality and a second image of said object generating by a second modality;
- classifying said detected region of concern;
- correlating said region of concern with a corresponding region in the other of said first image and said second image;
- and
- weighting said classification with a weighting factor corresponding to a degree of correlation,
- wherein said first modality is different from said second modality.
An imaging system for imaging an object, comprising:
- means for generating a first image of said object from x-ray radiation;
- means for generating a second image of said object from ultrasound;
- means for detecting a region of concern in at least one of said first image and said second image;
- means for correlating said detected region of concern with a corresponding region in the other of said first image and said second image;
- means for at least one of:
- determining whether said abnormality is present in said corresponding region in said other of said first image and said second image;
- and
- comparing at least one of:
- a shape of the detected region of concern;
- a size of the detected region of concern;
- a contrast of the detected region of concern;
- and
- a contrast distribution of the detected region of concern;
- means for classifying said abnormality;
- and
- means for weighting said classification in relation to a degree of correlation.
