This paper deals with a new approach of registration in multimodal imaging. Modalities involved are Digital Subtracted Angiography (DSA, 2D) and Magnetic Resonance Angiography (MRA, 3D). Our approach is an hybrid one, mixing feature and intensity based approaches. This approach is based on the extraction of a anatomical referential common to both MRA and(More)
We measured serum cholesterol, triglyceride, and lipoprotein Lp(a) concentrations in serum of 37 patients with massive proteinuria of different origin, comparing values with those for age- and sex-matched controls and finding significantly increased Lp(a) concentration in the total group of patients compared with controls. Lp(a) concentration was not(More)
This article presents a method for automatic segmentation of prostate from abdominal freehand ultrasound images. A statistical model of prostate is estimated from a manually delineated images. The segmentation starts by smoothing the image to enhance edges by applying a modified version of the adaptive filter which detects individual speckles and remove(More)
Conformal radiotherapy is a therapeutic method requiring medical imaging, generally CT images to obtain Hounsfield number and electronic density data indications. The use of MRI simultaneously with CT imposes to deform CT images and superimpose them on MR images. The aim of this paper is to propose a nonridgid matching method between the two modalities (CT(More)
