Detector coils inside the patient act as antennas, coupled to the magnetic resonance radio frequency transmit field, thereby making the catheter visible in an MR environment. The elongated transmission conductor which is attached to the coil is coupled to the RF field as well. This coupling heats the conductor, causing dangerous tissues heating, which has hindered the clinical use of MR-catheters up to now. Transmitting the signal wirelessly through induction coupling, between the coil on the catheter’s tip and a surface coil outside the patient, is a feasible way to avoid using the conductive transmission wire. However, induction coupling still encounters problems regarding catheter orientation and frequency splitting. The purpose of this work is to present a mathematical model for the frequency splitting to facilitate the matching and tuning processes. Also, to propose a novel design of two perpendicular uncoupled coils on the catheter tip to keep coupling at all orientations. These coils were fabricated with a multilayer fabrication process for flexible electronics on the microscale.","PeriodicalId":6710,"journal":{"name":"2019 IEEE SENSORS","volume":"92 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84062941","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 motivation is that obtaining high quality images requires the acquisition, processing and storage of a large amount of data so that, with sparsity (disabled some array elements positions in the reception), the amount of data to be stored should be reduced in order to increase the scan rate. The experiments of the proposed method were performed using simulated and in-vivo dataset available in the PICMUS website. The tests were performed using 128 elements for transmission and 128, 65, 44, and 23 elements sparsely distributed in the reception. The performance evaluation has been done using the Full Width at Half Maximum (FWHM) and the Contrast Ratio (CR). Results showed that the images generated by the proposed method, with reduced number of active elements in the reception, were close to those provided by DAS in terms of spatial resolutions and contrast, indicating that the proposed SMV method is suitable for ultrasound imaging.","PeriodicalId":6710,"journal":{"name":"2019 IEEE SENSORS","volume":"114 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76347351","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}

Our approach uses an additional IMU to detect the head acceleration of a patient and to correct the corresponding drift in the vestibular prosthesis. The algorithm includes four major parts. First, we extract features from the shoe-mounted IMU to classify human activities through convolutional neural networks. Second, we fuse data from the head-mounted IMU (vestibular prosthesis). Third, we artificially create additional data samples from a small pool of training data for each classification class. Fourth, we use the classified activities to calibrate the reading from the head-mounted IMU. The results indicate that during daily routine activities the firing rate baseline of a vestibular prosthesis system without calibration fluctuates between 100 pulses/s to 150 pulses/s; in contrast, an appropriate calibration to human activity results in correction of 4 pulses/s in extreme cases, providing a stable baseline firing rate while the head is not moving. In this work, we specifically study the contribution of gyroscope scale factor on the drift of the vestibular prosthesis system and propose a corresponding calibration method.","PeriodicalId":6710,"journal":{"name":"2019 IEEE SENSORS","volume":"54 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90966596","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}
