The current International Organization for Standardization (ISO) standard (ISO 8600-3: 1997 including Amendment 1: 2003) for determining endoscope field of view ( FOV) does not accurately characterize some novel endoscopic technologies such as endoscopes with a close focus distance and capsule endoscopes. ![]() Wang, Quanzeng Khanicheh, Azadeh Leiner, Dennis Shafer, David Zobel, Jurgen The details of potential savings in scan time and the signal-to-noise ratio (SNR) performance in comparison to i FOV scans for both phantom and in-vivo images are also described. The achieved FOV is experimentally validated by the point spread function (PSF) of a phantom scan. The proposed solution is built on the geometry of the PROPELLER trajectory permitting the scan prescription and data reconstruction to remain largely similar to standard PROPELLER. This work presents an empirical closed-form solution to adapt the PROPELLER trajectory for an e FOV. When imaging elongated objects, significant savings in scan time can potentially be achieved by supporting an elliptical field-of-view (e FOV). Traditionally two-dimensional scans are designed to support an isotropic field-of-view (i FOV). The imaging system also includes automated or manually controlled display system and software for providing an interactive graphical user interface (GUI) that displays a full 360-degree field of view and allows the user or automated ATR system to select regions for higher resolution inspection.Įlliptical field-of-view PROPELLER imaging. Each bank of imagers is controlled by a dedicated processing module in order to handle information flow and image analysis of the outputs of the camera system. The sensor head encloses a combination of wide field-of-view CMOS imagers and narrow field-of-view CMOS imagers. The imaging system includes a sensor head for scene acquisition, and a control apparatus inclusive of distributed processors and software for device-control, data handling, and display.
