PVI can be achieved by placing radio-frequency (RF) lesions contiguously around the pulmonary veins attached to the left atrium. Since accurate lesion placement may be difficult, pre-planned ablation lines can be used for better navigation both when using mapping systems or also when relying on fluoro overlay techniques. By working with physicians in this field, we learned that clinically acceptable ablation lines are not necessarily limited to a unique line, but there appears to be some flexibility when defining regions within which ablation should be performed. We present a novel method to investigate the dimensions of such a region based on comparing pre-planned ablation lines set up for different left atria. A common reference model is proposed as a means to combine and compare different pre-planned ablation lines. Based on our data, we found an average deviation of individually pre-planned ablation lines from their respective mean of 2.9±1.9 mm and 1.8±1.5 mm for right and left sided ipsilateral planning lines, respectively. Beyond ablation line assessment, this work also introduces a framework which can be extended to automatic pre-planning of ablation lines for PVI procedures.","PeriodicalId":178011,"journal":{"name":"2013 IEEE 10th International Symposium on Biomedical Imaging","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132517144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the current gold standard implementation, known as Chemical Shift Imaging (CSI), is plagued by various artifacts, due primarily to the limitations dictated through use of the Fourier transform. To counter these impediments, numerous “constrained” reconstruction methods have been suggested, which typically inject some type of a priori information, usually with the aid of structural MR images, into the signal model. While this may be desirable for some applications, it introduces an assumption which posits a general equivalency between the spatial and spectral distributions, which may not always be appropriate. This work examines an alternative formulation in which, with the aid of statistical techniques and spatial regularization, constituent high-resolution spatial and spectral components are estimated from the raw MRSI data. We demonstrate the efficacy of this technique, and the robustness of the estimated components to alternative sampling strategies, thereby broadening the applicability of the method and offering the prospect of reduced acquisition times in more pressed clinical settings.","PeriodicalId":178011,"journal":{"name":"2013 IEEE 10th International Symposium on Biomedical Imaging","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116331825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The success of the NL-means rests on the fact that there are typically enough such similar voxels in natural, and even medical images; in other words, that there is some self-similarity/redundancy in such images. However, similarity between voxels (or rather, between patches around them) is usually only assessed in a spatial neighbourhood of the voxel under study. As the human brain exhibits approximate bilateral symmetry, one could wonder whether a voxel in a brain image could be more accurately denoised using information from both ipsi- and contralateral hemispheres. This is the idea we investigate in this paper. We define and compute a mid-sagittal plane which best superposes the brain with itself when mirrored about the plane. Then we use this plane to double the size of the neighbourhoods and hopefully find additional interesting voxels to be included in the weighted sum. We evaluate this strategy using an extensive set of experiments on both simulated and real datasets.","PeriodicalId":178011,"journal":{"name":"2013 IEEE 10th International Symposium on Biomedical Imaging","volume":"120 1 Suppl 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116375035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
