We analyzed the excitation thresholds for three such waveforms, varying their timing parameters. Their thresholds were compared to the threshold of the monophasic waveform having the same active pulse duration. The results show that pseudo-monophasic thresholds are considerably higher than those of monophasic waveform having the same pulse duration for the shorter pulse durations, but tend to equalize towards long pulses, where it becomes practically irrelevant whether the waveform is purely monophasic or pseudo-monophasic. This case study was performed by computational nerve modeling and simulation using SENN (Spatially Extended Nonlinear Node) nerve model.","PeriodicalId":134768,"journal":{"name":"2018 EMF-Med 1st World Conference on Biomedical Applications of Electromagnetic Fields (EMF-Med)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121202528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SAR and temperature distributions were evaluated and relevant differences were found. Also, the large and unknown variation in blood perfusion results in a large uncertainty in the predicted temperature distributions.
