This device is able to manipulate the needle inside the closed-bore MRI scanner under the control of the interventional radiologist inside both the scanner room and the console room. The device consists of a 2 degrees of freedom (DOF) needle driver and an actuation box. The 2-DOF needle driver is placed inside the scanner bore and driven by the actuation box settled at the end of the table through a beaded chain transmission. This novel remote actuation design could reduce the weight and profile of the needle driver that is mounted on the patient, as well as minimize the potential imaging noise introduced by the actuation electronics. The actuation box is designed to perform needle intervention in both manual and motorized fashion by utilizing a mode switch mechanism. A mechanical hard stop is also incorporated to improve the device's safety. The bench-top accuracy evaluation of the device demonstrated a small mean needle placement error (<i><</i> 1 mm) in a phantom study.</p>","PeriodicalId":72029,"journal":{"name":"...

The electrical activity of the brain along the scalp suffered from sleep apnea using Electroencephalogram (EEG) is addressed. The correlation between the EEG signals was compared to detect the features of sleep apnea. The Empirical Mode Decomposition (EMD) and Bivaiiate were adopted in this project to evaluate the extracted EEG signals. The performance of EMD has greatly improved when the number of samples was decreasing. The segmentation error analyzed in the Event Related Potential (ERP) reflected the occurrence of apnea. The delta power associated to the body autonomous system and homeostasis regulation is due to the drop of oxygen when sleep apnea happened. Using Hilbert Huang Transform, there is energy waveform in low frequencies when an apnea has happened. These can be linked to the delta power which relates to the body autonomous system and homeostasis regulation. The EMD, EEMD and Bivariate methods were compared to show key features linked with apnea for analysis purposes.","PeriodicalId":72029,"journal":{"name":"...
