Cross-time and cross-modality medical diagnosis

Abstract

A cross-time and cross-modality inspection method for medical image diagnosis. A first set of medical images of a subject is accessed wherein the first set is captured at a first time period by a first modality. A second set of medical images of the subject is accessed, wherein the second set is captured at a second time period by a second modality. The first and second sets are each comprised of a plurality of medical image. Image registration is performed by mapping the plurality of medical images of the first and second sets to predetermined spatial coordinates. A cross-time image mapping is performed of the first and second sets. Means are provided for interactive cross-time medical image analysis.

Description

technical field [0001] The present invention relates to digital image processing methods for image analysis, and in particular to cross-temporal and cross-morphological examination of tissues of different natures (eg, abnormal and normal tissues) in medical images. Background technique [0002] Digital imaging for medical applications was made possible in the 1970's by the clinical use of, for example, computed tomography (CT) scanners. Since then, the use of x-ray imaging has advanced diagnostic imaging techniques, along with the advent of digital computers and new imaging modalities such as ultrasound and magnetic resonance imaging (MRI). [0003] The use of digital medical imaging technology brings benefits to health care. For example, angiography procedures, which view blood vessels in the brain, kidneys, arms and legs, and heart, have benefited from the use of digital medical imaging and image processing. [0004] With digital imaging, computerized multidimensional (e...

Problems solved by technology

[0013] Studies of such curves / parameters have been used clinically to identify and delineate malignant or benign tumoroids, but success has been variable due to usually good sensitivity but often poor specificity (eg, see "MRI of the breast" (S.C. Rankin "MRI of the breast", Br. J. Radiol 73, pp 806-818, 2000))
