A Clinical Research on Real-Time Monitoring of Cerebral Edema After Basal Ganglia Hemorrhage Based on Near-Field Coupling Phase Shift Technology
A novel method was developed based on near-field coupling phase shift (NFCPS) to perform non-contact and bedside monitoring of cerebral edema in the intensive care unit (ICU). A total of 17 subjects were selected to conduct real-time NFCPS monitoring of cerebral edema and divided into surgical group...

The surgical group had the most drastic changes (-3.42 ± 6.0 degrees, at 12 h; -12.85 ± 10.58 degrees, at 24 h; -5.04 ± 2.65 degrees, at 36 h; 0.05 ± 5.74 degrees, at 48 h).

Continuous collection was conducted for 15 min at each time point and then the phase shift was recorded as the NFCPS value. The computed tomography (CT) images of the surgical group and the conservative group were obtained at the same time points.
