Synchronization control of pulsatile ventricular assist devices by combination usage of different physiological signals

Li, Xinghui; Zhong, Lunchao; Luo, Lin; Zhu, Shidong; Ni, Kai; Zhou, Qian; Yang, Bibo; Wang, Xiaohao

2019 Computer Assisted Surgery

doi:10.1080/24699322.2018.1560089 pmid:30760103

AbstractThree different types of synchronous control methods based on physiological parameters, electrocardiogram (ECG) and fixed systole, ECG and aortic pressure, and ECG and phonocardiogram (PCG) were used to trigger a proposed intra-ventricular assist device (iVAD). The ECG, aortic pressure,...

The role of the precuneus and posterior cingulate cortex in the neural routes to action

Wang, Zijian; Fei, Liu; Sun, Yaoru; Li, Jie; Wang, Fang; Lu, Zheng

2019 Computer Assisted Surgery

doi:10.1080/24699322.2018.1557903 pmid:30607999

AbstractNeural substrates of action to the object or this specific direct route, however, remain unclear, especially for the connection from the visual pathway to the motor cortex. The study examined this issue by conducting an fMRI experiment, in which two action generation tasks involving...

Influence of extracerebral layers on estimates of optical properties with continuous wave near infrared spectroscopy: analysis based on multi-layered brain tissue architecture and Monte Carlo simulation

Zhang, Yan; Liu, Xin; Wang, Qisong; Liu, Dan; Yang, Chunling; Sun, Jinwei

2019 Computer Assisted Surgery

doi:10.1080/24699322.2018.1557902 pmid:30676092

AbstractContinuous wave near-infrared spectroscopy (CW-NIRS) can be used to measure cerebral activity because it is noninvasive, simple and portable. However, the performance of the continuous wave near-infrared spectroscopy is distorted by the presence of extracerebral layer. Change of optical...
