The research on electromagnetic detection technology for brain diseases requires precise simulation of the human head. This article combines high-precision computed tomography (CT) images and magnetic resonance imaging (MRI) to establish an numerical model head with a real anatomical structure. (1) It had Asian characteristics encompassed 14 different structures, including skin, muscles, cranial bones, cerebrospinal fluid, cerebral veins, arteries, gray matter, white matter brain, basal...
Abstract Background:
Microwave detection is a prospective method in promptly identifying strokes, thereby facilitating clinical intervention and improved prognosis. We aimed to explore the factors affecting microwave stroke results, including brain tissue volume, composition, motion artifacts.
Methods:
Various conductivities were simulated using different concentrations of sodium chloride solutions. Physical experiments conducted utilizing system, with observations...
Early diagnosis and continuous monitoring are the key to emergency treatment intensive care of patients with acute ischemic stroke (AIS). Nevertheless, there has not been a fully accepted method targeting assessment AIS in clinical.
Cerebral edema (CE) is a non-specific pathological swelling of the brain secondary to any type neurological injury. The real-time monitoring focal CE mostly found in early stage great significance reduce mortality and disability. Magnetic Induction Phase Shift (MIPS) expected achieve non-invasive continuous CE. However, most existing MIPS sensors are made hard materials which makes it difficult accurately retrieve information. In this article, we designed conformal two-coil structure...
Closed cerebral hemorrhage (CCH) is a common symptom in traumatic brain injury (TBI) patients who suffer intracranial with the dura mater remaining intact. The diagnosis of CCH prior to hospitalization and early stage disease can help get earlier treatments that improve outcomes. In this study, noncontact, portable system for TBI-induced detection was constructed measures magnetic induction phase shift (MIPS), which associated mean conductivity caused by ratio between liquid (blood/CSF...
Abstract The hemorrhagic and the ischemic types of stroke have similar symptoms in early stage, but their treatments are completely different. timely effective discrimination two can considerable improve patients' prognosis. In this paper, a 16-channel noncontact microwave-based detection system was proposed demonstrated for potential differentiation stroke. animal experiments, 10 rabbits were divided into groups. One group consisted five cerebral hemorrhage models, other ischemia models....
Abstract Background As a serious clinical disease, ischemic stroke is usually detected through magnetic resonance imaging and computed tomography. In this study, noninvasive, non-contact, real-time continuous monitoring system was constructed on the basis of induction phase shift (MIPS) technology. The “thrombin method”, which conformed to pathological development process stroke, used construct an acute focal cerebral ischemia model rabbits. MIPS measurement, “symmetric cancellation-type”...
Abstract Background To investigate the feasibility of intracranial pressure (ICP) monitoring after traumatic brain injury (TBI) by electromagnetic coupling phase sensing, we established a portable shift (ECPS) test system and conducted comparison with invasive ICP. Methods TBI rabbits’ model were all synchronously monitored for 24 h ECPS testing We investigated abilities to detect targeted ICP feature extraction traditional classification decision algorithms.

Acute cerebral ischemia is an important clinical disease that usually detected by magnetic resonance imaging or computed tomography.The inductive phase shift (MIPS) a new method for detecting diseases, which non-invasive, miniaturized, and low-cost.A total of 25 rabbits were studied using two-coil sensor with 0.3-200 MHz frequency range, all the subjects measured 1 hour.Based on rabbit acute model, divided into unilateral ligation, bilateral non-ligation groups.The results showed average...
Cerebral blood flow (CBF) monitoring is of great significance for treating and preventing strokes. However, there has not been a fully accepted method targeting continuous assessment in clinical practice. In this work, we built noninvasive system cerebral pulsation (CBFP) that based on magnetic induction phase shift (MIPS) technology designed physical model the middle artery (MCA). Physical experiments were carried out through different simulations CBF states. Four healthy volunteers...
Introduction: Intracerebral hemorrhage (ICH) is a devastating disease with high rates of mortality and disability. The survival rate postoperative outcome ICH can be greatly improved through prompt diagnosis treatment. CT MRI are now the gold standards for ICH, but they not practical use in pre-hospital emergencies or at bedside monitoring. Methods: Based on earlier research detection single parallel plate electrode sensor, we developed 16-electrode Electrical Capacitance Tomography (ECT)...
Abstract Background Cerebral edema is an extremely common secondary disease in post-stroke. Point-of-care testing for cerebral types has important clinical significance the precise management to prevent poor prognosis. Nevertheless, there not been a fully accepted bedside method that. Methods A symmetric cancellation near-field coupling phase shift (NFCPS) monitoring system established based on symmetry of left and right hemispheres fact that unilateral lesions do affect healthy hemispheres....
