  4. Cemil Goksu, Pascal Haigron, Oscar Acosta, and Antoine Lucas. Endovascular navigation based on real/virtual environments cooperation for computer assisted team procedures. In Proceedings of spie: visualization, image-guided procedures and display, volume 5367, San Diego, USA, pages 257-266, 2004.
    Abstract:
    Transfemoral Endovascular Aneurysm Management, the less invasive treatment of Aortic Abdominal Aneurysms (AAA), is a highly specialized procedure, using advanced devices and requiring a high degree of clinical expertise.There is a great need for a navigation guidance system able to make this procedure safer and more precise. In this context of computer-assisted minimally invasive interventional procedures, we propose a new framework based on the cooperation between the real environment where the intervention takes place and a patient-specific virtual environment, which contains a virtual operating room including a C-arm model as well as the 3D preoperative patient data. This approach aims to deal with the problem of lack of knowledge about soft tissue behavior by better exploiting available information before and during the intervention through a cooperative approach. In order to assist the TEAM procedure in standard interventional conditions, we applied this framework to design a 3D navigation guidance system, which has been successfully used during three TEAM interventions in the operating room. Intra-operatively, anatomical feature-based 2D/3D registration between a single 2D fluoroscopic view, reproduced from the pose planned in the virtual environment, and the preoperative CT volume, is performed by means of a chamfer distance map. The 3D localization of the endovascular devices (sheath, guide wire, prosthesis) tracked either interactively or automatically on 2D sequences, is constrained to either the 3D vascular tree or a 3D device model. Moreover, we propose a first solution to take into account the tissue deformations during this particular intervention and to update the virtual environment with the intraoperative data.

MR coil sensitivity inhomogeneity correction for plaque characterization in carotid arteries. In SPIE'04, volume 5370 of Image Processing, San Diego, CA, USA, pages 2114-2121, May 2004. SPIE. Keyword(s): Arteries, carotid arteries, carotid artery, Correction, Inhomogeneity correction, MR, plaque.
    Abstract:
    We are involved in a comprehensive program to characterize atherosclerotic disease using multiple MR images having different contrast mechanisms (T1W, T2W, PDW, magnetization transfer, etc.) of human carotid and animal model arteries. We use specially designed intravascular and surface array coils that give high signal-to-noise but suffer from sensitivity inhomogeneity. With carotid surface coils, challenges include: (1) a steep bias field with an 80\% change; (2) presence of nearby muscular structures lacking high frequency information to distinguish bias from anatomical features; (3) many confounding zero-valued voxels subject to fat suppression, blood flow cancellation, or air, which are not subject to coil sensitivity; and (4) substantial noise. Bias was corrected using a modification of the adaptive fuzzy c-mean method reported by Pham et al. (IEEE TMI, 18:738-752), whereby a bias field modeled as a mechanical membrane was iteratively improved until cluster means no longer changed. Because our images were noisy, we added a noise reduction filtering step between iterations and used about 5 classes. In a digital phantom having a bias field measured from our MR system, variations across an area comparable to a carotid artery were reduced from 50\% to <5\% with processing. Human carotid images were qualitatively improved and large regions of skeletal muscle were relatively flat. Other commonly applied techniques failed to segment the images or introduced strong edge artifacts. Current evaluations include comparisons to bias as measured by a body coil in human MR images.

    Abstract:
    We are characterizing atherosclerotic disease in patients and animal models using multiple MR images having different contrasts such as T1-weighted, T2-weigted, and proton density weighted. We use intravascular and surface array coils giving good signal sensitivity but significant inhomogeneity. Because multiple images are obtained, it is desirable to acquire images quickly, limiting the signal to-noise ratio (SNR). In human carotid images, bias was corrected using a modified adaptive fuzzy c-mean method with a mechanical membrane model of the bias field [1]. Noise reduction filtering, background segmentation, outlier class identification, and signal normalization were all designed to address specific technical issues such as the noise, steepness of the sensitivity fall-off, and absence of signal near regions of interest due to fat suppression and blood flow compensation. In a synthetic image having a bias field measured from our MR system, variations across an area comparable to a carotid artery were reduced from 60\% to <5\% with processing while the misclassification rate was kept below 4\% even with a poor SNR of <7. Human carotid images were qualitatively improved and large regions of skeletal muscle were quantitatively flattened and normalized for inter- and intra-subject variation. The method will facilitate interpretation of artery gray scales for manual plaque characterization and enable computerized plaque classification.
