Evaluation of flushing parameters for clear view vascular endoscopy

Abstract Vascular diseases like aneurysms or atherosclerosis belong to the leading causes of death. For diagnosis and treatment, medical imaging is essential. Standard methods are Ultrasound, X-ray-based Angiography, Computed tomography Magnet Resonant Imaging. Additionally, Intravascular Ultrasound Optical Coherence Tomography available for intravascular imaging. One technique direct investigation inner vessel vascular endoscopy, also called angioscopy. It based on insertion an optical endoscope into blood Dependent diameter, these endoscopes have be very small. Angioscopy can provide valuable information about condition wall serve procedure observation implant assessment. But angioscopy requires absence a clear field view. In prior research, we already developed placement tiny fiber inside catheter combination. As essential step toward clinical study, now want evaluate flushing parameters needed achieve view endoscope. The affected by flow diameter. We designed test setup that allows angioscopic examination simulation realistic conditions, such as different diameters includes pattern image quality
