BACKGROUND Intramyocardial cell injections in the context of cardiac regenerative therapy can currently be performed using electromechanical mapping (EMM) provided by the NOGA®XP catheter injection system. The gold standard technique to determine infarct size and location, however, is late gadolinium enhanced magnetic resonance imaging (LGE-MRI). In this article we describe a practical and accu...

We propose a new framework to register and fuse TransVaginal Ultrasound (TVUS) and Magnetic Resonance (MR) Images. The proposed method, first establishes optimal correspondences between pairs of curves by fixing the optimal re-parametrization between each pair of corresponding organ boundaries. Then, the deformation field is interpolated using Cubic Hermite Finite Element (CHFE). As a result, o...

The analysis of different image modalities is frequently performed in ophthalmology as they provide complementary information for the diagnosis and follow-up of relevant diseases, like hypertension or diabetes. This work presents an hybrid method for the multimodal registration of color fundus retinography and fluorescein angiography. The proposed method combines a feature-based approach, using...

We present a novel methodology for combining breast image data obtained at different times, in different geometries, and by different techniques. We combine data based on diffuse optical tomography (DOT) and magnetic resonance imaging (MRI). The software platform integrates advanced multimodal registration and segmentation algorithms, requires minimal user experience, and employs computationall...

This work investigates a novel 3D multimodal deformable registration method to align high-resolution magnetic resonance imaging (MRI) with cine MRI of the tongue for better visual and motion analysis. Both modalities have different strengths to characterize and analyze the tongue structure or motion. Visual and motion analysis of combined anatomical and temporal information can synergistically ...

A secured system process is becoming a tough process to validate the online users. In an online process, normally user name and password is given for user registration. But since this alone is not sufficient for security, biometric identifier, fingerprint is used in registration step using a fingerprint device. In this paper, an additional security parameter, signature using mouse, that is, key...

This paper presents the principle of multimodal and multi-informational neuronavigation as well as the data fusion environment we have developed for these techniques. Our fusion environment supports the planning step and includes registration, segmentation, 3D visualisation as well as data browsing and interaction tools. We provide a neuronavigation system with relevant information for the perf...

Different modalities can be achieved by the maximization of suitable statistical similarity measures within a given class of geometric transformations . The registration functions are less sensitive to low sampling resolution, do not contain incorrect global maxima which are sometimes found in the mutual information. This paper proposes a novel and straightforward multimodal image registration ...

Image registration is an important issue in medical analysis. In this process the spatial transformation that aligns the reference image and the floating image is estimated by optimizing a similarity metric. Mutual information (MI), a popular similarity metric, is a reliable criterion for medical image registration. In this paper, we present an improved method for multimodal image registration ...
