Classification with CNN features and SVM on Embedded DSP Core for Colorectal Magnified NBI Endoscopic Video Image

Flexible fibre optic endoscopes were developed in the mid-1960s, leading to the growth of gastrointestinal endoscopy as we now know it. The recent availability of cheaper, miniaturized colour chips has led to the development of video endoscopes, providing an excellent clear view that does not deteriorate with age (as it does with fibre optic devices). With improvements in software, the endoscopic video image can be magnified: modern instruments will zoom up to 25 × magnification, and mucosal detail can also be enhanced electronically so that small lesions a few millimetres in size can be seen quite clearly. The modern video endoscope image can be instantly printed out and archived digitally on a computer system....

This document describes the surgical robot console system based on 3D Slicer for image-guided surgery. Considering the image-guided surgery, since image workstations have complex User Interface (UI) and extra functions, it is supposed that such UI is not suitable for surgeon who is the robot operator. The proposed robot console is designed as a simple UI for the robot operator, which can display the endoscopic video image, the sensor data, the robot status and simple images for guiding the surgery. Therefore, we expect that the surgeon can concentrate on the operation itself by utilizing the robot console. On the other hand, since the robot console system is based on 3D Slicer, the robot console can use the abundant image operation functions. Moreover, it can use the flexibility of tool connectivities by using the OpenIGTLink protocol. In addition, since the video image is captured by using the multifunctional library OpenCV , we can expect the extensibility about the function of the proposed system.

We report a novel method of reconstructing the 3D structure of the prostatic urethra and measuring its elasticity using endoscopic video images, and discuss their relation to clinical relevancy. Information regarding pixel color and brightness in the endoscopic video image is converted to relative distance between the object and the light source. An opened, 3D image of the prostatic urethra is obtained from a video image captured by the endoscope as it is slowly pulled through the urethra. The elasticity of the urethra is determined by recording a video image of the endoscope fixed in the prostatic urethra, with and without irrigation under water pressure of approximately 80 cm H 2 O . Angulation of the prostatic urethra is estimated by the number of intersections between the outline of protruded prostate and the midline of the urethra in patients with severe voiding dysfunction scheduled for transurethral resection of prostate, and in those scheduled for transurethral resection of bladder tumor without apparent discomfort during urination. The number of intersections showed a relationship with voiding symptoms. In conclusion, reconstruction of the 3D structure of the prostatic urethra from endoscopic video images is a feasible method that shows promise for estimating the mechanism of voiding dysfunction.
