An Efficient Method for Segmentation of MRI Spine Images

Intervertebral disc segmentation in MR images using anisotropic oriented flux

“…Nonetheless, the watershed based algorithm persistently encounters an over-segmentation issue. To exploit the directional image features, a hough transform based approach was presented by Shi et al (2007). Its performance on a large dataset is unknown as it was evaluated qualitatively using one image.…”

Fully automatic extraction of human spine curve from MR images using methods of efficient intervertebral disk extraction and vertebra registration

“…Finally, the vertebrae were segmented by connectivity tracing of edges of the vertebrae. Shi [11] proposed a method that used a statistic spine cord model to extract the spine cord. Then, based on the spine cord position, intervertebral disks were segmented.…”

“…Within these slices, only one or two of them, which include a complete spine, are suitable for processing. Currently, most methods require to manually point out the suitable slice (e.g., in [11]). Furthermore, most methods use very complicate algorithms to obtain candidate positions of vertebrae (e.g., in [4]) or intervertebral disks (e.g., in [7]) and even manual selection (e.g., in [6]).…”

A Novel Method VESTAL to Label Lumber Vertebrae and Intervertebral Discs

“…Their approach is based on a Markov-chain-like graphical model of the ordered discs and vertebrae in the lumbar spine. Ruiqiong Shi et al [7] proposed semi-automatic method to detect disc in spine. In preprocessing, average values for window, vertebrae length and width are calculated.…”

“…In literature most of the authors proposed methods based on reference points or MR Images in standard position [5][6][7]. The selection of reference point plays a key role in labelling and it depends on the expertise of radiologist.…”
