2014 Medical Image Analysis  
In this study, we propose a method for automatic segmentation of intra-cochlear anatomy in post-implantation CT of unilateral recipients, thus eliminating the need for pre-implantation CTs in this population  ...  The approach is to segment the intra-cochlear anatomy in the pre-implantation CT, localize the electrodes in the post-implantation CT, and register the two CTs to determine relative electrode array position  ...  The content is solely the responsibility of the authors and does not necessarily represent the official views of this institute.  ...

An artifact-robust, shape library-based algorithm for automatic segmentation of inner ear anatomy in post-cochlear-implantation CT

Fitsum A. Reda, Jack H. Noble, Robert F. Labadie, Benoit M. Dawant, Sebastien Ourselin, Martin A. Styner
2014 Medical Imaging 2014: Image Processing  
In this work, we present an algorithm for automatically segmenting intra-cochlear anatomy in post-implantation CTs.  ...  Pre-implantation CT has been necessary because it is difficult to localize the intra-cochlear structures in post-implantation CTs alone due to the image artifacts that obscure the cochlea.  ...  Thus far, the shape of the cochlea and intra-cochlear anatomy has been determined using a pre-implantation CT, which we then register to a post-implantation CT.  ...

2019 Medical Imaging 2019: Image Processing  
In IGCIP, we segment the intra-cochlear anatomy and localize the electrode arrays in the patient's head CT image.  ...  To segment the intra-cochlear anatomy, we use an active shape model (ASM)-based method. Though it produces satisfactory results in most cases, sub-optimal segmentation still happens.  ...  In IGCIP, we use image processing algorithms to automatically segment the intra-cochlear anatomy, typically in the patient's pre-operative CT image [2] , and to localize the electrode array in the post-operative  ...

2011 IEEE Transactions on Biomedical Engineering  
Segmentation of intra-cochlear cavities could thus aid the surgeon to choose the point of entry and angle of approach that maximize the likelihood of successful implant insertion, which may lead to more  ...  However, because the membrane that separates the intra-cochlear cavities is too thin to be seen in conventional in vivo imaging, traditional segmentation techniques are inadequate.  ...  An earlier version of this paper was printed in the Proceedings of the SPIE Conf. on Medical Imaging 2010: Image Processing, pp. 762302.  ...
