Machine learning-based colon deformation estimation method for colonoscope tracking [PDF]
SPIE Medical Imaging 2018: Image-Guided Procedures, Robotic
Interventions, and Modeling, 2018 This paper presents a colon deformation estimation method, which can be used to estimate colon deformations during colonoscope insertions. Colonoscope tracking or navigation system that navigates a physician to polyp positions during a colonoscope ...

Tracking accuracy evaluation of electromagnetic sensor-based colonoscope tracking method [PDF]
Computer-Assisted and Robotic Endoscopy, LNCS 9515, pp.101-108,
2015, 2022 This paper reports a detailed evaluation results of a colonoscope tracking method. A colonoscope tracking method utilizing electromagnetic sensors and a CT volume has been proposed. Tracking accuracy of this method was evaluated by using a colon phantom.

Colon Shape Estimation Method for Colonoscope Tracking using Recurrent Neural Networks [PDF]
Published in Proceedings of MICCAI 2018, LNCS 11073, pp 176-184, 2020 We propose an estimation method using a recurrent neural network (RNN) of the colon's shape where deformation was occurred by a colonoscope insertion. Colonoscope tracking or a navigation system that navigates physician to polyp positions is needed to reduce such complications as colon perforation. Previous tracking methods caused large tracking errors

Clinical Medicine Insights: Pathology, 2018 Perineurioma is a mesenchymal neoplasm best known in soft-tissue pathology. A colonic perineurioma is a relatively recently described entity and sometimes encountered in specimens from the large intestine, especially distal colon. Without its recognition, a perineurioma can be misdiagnosed as other more common gastrointestinal spindle cell neoplasms ...

Proceedings of the National Academy of Sciences of the United States of America, 1999 Oligonucleotide arrays can provide a broad picture of the state of the cell, by monitoring the expression level of thousands of genes at the same time. It is of interest to develop techniques for extracting useful information from the resulting data sets.

Comprehensive molecular characterization of human colon and rectal cancer
Nature, 2012 To characterize somatic alterations in colorectal carcinoma, we conducted a genome-scale analysis of 276 samples, analysing exome sequence, DNA copy number, promoter methylation and messenger RNA and microRNA expression.

Colon capsule endoscopy for colonic surveillance [PDF]
Colorectal Disease, 2019 AbstractAimResources used in surveillance colonoscopies are taking up an increasing proportion of colonoscopy capacity. Colon capsule endoscopy (CCE) is a promising technique for noninvasive investigation of the colon. We aimed to investigate CCE as a possible filter in colonic surveillance with the primary outcome of reducing the number of ...
