Cerebral hemorrhage, which is an important clinical problem, is often monitored and studied using expensive devices, such as magnetic resonance imaging (MRI) and positron emission tomography (PET) that are unavailable in economically underdeveloped regions. Magnetic induction tomography (MIT) is a new type of non-contact, non-invasive, and low-cost(More)
Cerebral hemorrhage is an important clinical problem that is often monitored and studied with expensive techniques, such as computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). These devices are not readily available in economically underdeveloped regions of the world and in emergency departments and emergency(More)
Based on PSSMI we developed a new cerebral hemorrhage model and a new system for cerebral hemorrhage detection. This study evaluated experimentally the performance of our system through the simulation of phase shift measurements. Some phase shifts were measured at three operation frequencies. The phase resolution was up to 0.005° and the gain was(More)
Cerebral hemorrhage, a difficult issue in clinical practice, is often detected and studied with computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). However, these expensive devices are not readily available in economically underdeveloped regions, and hence are unable to provide bedside and emergency on-site(More)
Intracranial hemorrhage (ICH) is the bleeding induced by parenchyma vascular rupture. In this paper, four novel coils (a contralateral hemisphere cancellation coil, a coaxial coil, a double-end exciting coil, and a Helmholtz coil) were developed to detect the volume change of ICH with the magnetic induction phase shift (MIPS) technique. Both numerical(More)
This study was aimed to improve the sensitivity of magnetic induction phase shift detection system for cerebral hemorrhage. In the study, a cerebral hemorrhage model with 13 rabbits was established by injection of autologous blood and the cerebral hemorrhage was detected by utilizing magnetic induction phase shift spectroscopy (MIPSS) detection method under(More)
BACKGROUND The major therapy for ischemic stroke is thrombolytic treatment, but severe consequences occur when this method is used to treat hemorrhagic stroke. Currently, computed tomography and magnetic resonance imaging are used to differentiate between two types of stroke, but these two methods are ineffective for pre-hospital care. METHODS We(More)
The real-time monitoring and evaluation of the severity and progression of cerebral hemorrhage is essential to its intensive care and its successful emergency treatment. Based on magnetic induction phase shift technology combined with a PCI data acquisition system and LabVIEW software, this study established a real-time monitoring system for cerebral(More)
Cerebral edema is a common disease, secondary to craniocerebral injury, and real-time continuous monitoring of cerebral edema is crucial for treating patients after traumatic brain injury. This work established a noninvasive and noncontact system by monitoring the magnetic induction phase shift (MIPS) which is associated with brain tissue conductivity.(More)
In vivo sampling of interstitial fluid using microdialysis (MD) fibers has become a standard and accepted procedure. The resulting small volume samples, often with low concentrations of the analyte of interest, present a particular challenge to analytical methods. Rapid developments of analytical techniques with high sensitivity accelerate their combination(More)
