Background/Objectives: Microwave imaging can obtain anatomical and functional images of the colon has demonstrated to detect polyps based on their dielectric properties. This study aims evaluate feasibility, safety performance micro-wave-based colonoscopy for diagnosis in humans. Methods: single-center, prospective, observational study. Patients referred elective outpatient diagnostic co-lonoscopy were included. A device provided with microwave antennas was attached tip a conventional...
Background/Objectives: Colonoscopies have some limitations that result in a miss rate detection of polyps. Microwave imaging has been demonstrated to detect colorectal polyps based on their dielectric properties synthetic phantoms, ex vivo tissues and animal models. This study aims evaluate, for the first time, feasibility, safety performance microwave-based colonoscopy diagnosis real-time explorations humans. Methods: was single-center, prospective, observational study. Patients referred...
In this letter, a three-dimensional (3-D) printed compact ultrawideband (UWB) extended gap ridge horn (EGRH) antenna designed to be used for biological measurements of the human body is described. The operational frequency covers microwave band interest from 0.5 3.0 GHz (for an <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$S_{11}$</tex-math></inline-formula> under...
A system to integrate microwave imaging with optical colonoscopy is presented. The overarching goal improve the prevention and early diagnosis of one main health economic burdens an increasingly aging population, i.e., colorectal cancer. For a colonoscopy, gold standard for cancer diagnosis, 22% polyps are not detected, risk after negative can be up 7.9%. To remedy this, able generate alarm when polyp detected designed, manufactured validated colon phantom composed tissue-mimicking...
Providing cellular network services inside residential or office buildings has become challenging, especially for fifth-generation networks that use higher carrier frequencies. Additionally, new energy-efficient contain envelopes such as low-emissivity glass and multi-layer thermal insulations, all of which - unintendedly but effectively also block radio signals. As a solution to those problems indoor coverage, we suggest the passive antenna systems embedded into building walls. We propose...
Microwave imaging can obtain 360° anatomical and functional images of the colon representing existing contrast in dielectric properties between different tissues. Microwaves are safe (nonionizing) have potential reducing visualization problems conventional colonoscopy. This study assessed efficacy a microwave-based colonoscopy device to detect neoplastic lesions an ex vivo human model. Fresh surgically excised colorectal specimens containing cancer or polyps were fixed 3D positioning system,...
This study assesses the efficacy of detecting colorectal cancer precursors or polyps in an ex vivo human colon model with a microwave colonoscopy algorithm. Nowadays, 22% go undetected conventional colonoscopy, and risk after negative can be up to 7.9%. We developed device that consists cylindrical ring-shaped switchable antenna array attached tip colonoscope as accessory. The accessory is connected external unit allows successive measurements processes imaging An acoustic signal generated...
Early detection and resection of colon polyp is the best way to reduce colorectal cancer (CRC) mortality. The current method for early colonoscopy, which has a limited field view, its efficacy highly dependant on endoscopist's experience preparation. This work presents device combining microwave imaging with optical colonoscopy. challenges this new system are presented, such as unknown distance mucosa, leads undesired scattered fields and, antenna size limitations. Four dynamic calibration...
Colonoscopy is currently the most effective way of detecting colorectal cancer and removing polyps, but it has some drawbacks can miss up to 22% polyps. Microwave imaging potential provide a 360° view colon addresses limitations conventional colonoscopy. This study evaluates feasibility microwave-based colonoscopy in an vivo porcine model.A prototype device with microwave antennas attached endoscope was tested on four healthy pigs three gene-targeted mutations adenomatous polyposis coli...
Aims Microwave imaging has demonstrated to detect polyps based on their dielectric properties in ex-vivo colon tissues and in-vivo porcine model. The aim of this study is evaluate the feasibility safety microwave-based colonoscopy for diagnosis humans [1] [2].
Abstract A system to integrate microwave imaging with optical colonoscopy is presented. The overarching goal improve the prevention, diagnosis and understanding of one main health economic burdens an increasingly ageing population that colorectal cancer. Our can address two challenges – detection precancerous lesions called polyps classify them according their malignancy moves forward a major trend field automating medical explorations. To do so, complete able emit alarm when polyp detected...
Colon phantoms that replicate a real colon dielectric properties, shape, and texture are required to verify microwave colonoscopy system. The realism accuracy of the phantom quantified in this study using method based on antenna bandwidth variation.
Colonic lipomas are benign submucosal lesions which exceptionally may associate with colonic neoplasia or adenoma. LST-NG pseudo-depressed type over 2 cm commonly require en-bloc resection ESD other alternative techniques.
