Algorithms correctly identified 100% of the trials analyzed, using manually analyzed video recordings as a ground-truth. In addition, visual analysis suggests that IMU data is able to differentiate between task expert and task naïve participants, potentially allowing for performance indicators to be derived. Results from this preliminary study suggest strong potential for IMUs to be a useful tool for sports analytics in para ice-hockey.","PeriodicalId":152478,"journal":{"name":"2020 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121792625","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 main aim of the overall research project is the realization of an Internet-connected device able to allow the execution of standardized tests and to share results with specialized medical centers. At this stage, the system has been focused on two parameters useful for medical exams: tremor and hands trajectory. This paper describes the realized set-up based on fixed receiving coils and one mobile transmitting coil. It reports preliminary experimental results based on a robotic arm adopted as a reference. Obtained results clearly show the capability of the realized system to accurately estimate both the tremor frequency and the hand trajectory, even if high levels of tremor are applied.","PeriodicalId":152478,"journal":{"name":"2020 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123589663","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}

Saccomandi","doi":"10.1109/MeMeA49120.2020.9137230","DOIUrl":"https://doi.org/10.1109/MeMeA49120.2020.9137230","url":null,"abstract":"Minimally invasive techniques are gaining a major role in treating superficial gastrointestinal cancers. Energy-based approaches have been investigated as potential alternative to the gold-standard techniques (e.g., Endoscopic Submucosal Dissection). Among these techniques, the laser has been studied for achieving a selective ablation of the gastric mucosa. Together with the optimization of the laser settings for avoiding tissue perforation or insufficient ablation, a tool providing quantitative information about the intraoperative tissue state can support the treatment guidance. This work aims at providing a novel non-invasive approach based on the use of hyperspectral imaging (HSI) for monitoring ablative therapy in in vivo gastric mucosa. The three-dimensional datasets generated by the HSI provide spatial and spectral information of the scene, thus collecting tissue optical features during the ablation therapy in each pixel of the images. The operation of a diode laser focused on the porcine gastric mucosa was controlled in accordance with chosen temperature thresholds (i.e., 36, 60, 70, 80, 100, 110 °C), measured with a thermographic camera. HSIs of the living gastric mucosa undergoing laser procedure hold diagnostic information about the thermal outcome. Two tests have been performed, and the temperature dependence of three characteristic spectral wavelengths have been analysed: oxyhemoglobin (Hb02) in the visible range 500-600 nm, methemoglobin (metHb) around 630 nm, and deoxyhemoglobin (Hb) at 760 nm. The data have been processed in terms of absorbance at the set temperature relative to the absorbance at initial body temperature (36 °C). After 60 °C the percentage relative absorbance of metHb increased significantly in both tests (i.e., 92.3±1.9 % at 70 °C and 229.4±4.7% at 100 °C in Test2); regarding the Hb at 110 °C, Test1 reported an increase of 43.8±1.7 %, versus 127.2±3.8% in the Test2. On the other hand, HbO2 chromophore experiences an increase only for the first stages of heating later decreasing in favour of metHb and Hb formation.In both tests, similar trends for characteristic wavelengths are found, thus demonstrating the potential of the HSI measurement in laser-induced thermal damage monitoring. Although optical response show dependence on the tissue type and condition, this finding encourages future studies to standardize this promising technique.","PeriodicalId":152478,"journal":{"name":"2020 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131315935","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}

In this paper, a novel automated image acquisition and analysis system combining an infrared thermal camera with a RGB-D sensor is proposed for detection of NEC in preterm newborns. Calibration procedures are defined to ensure frame synchronization and observation consistency among the color, depth and infrared images. Segmentation and extraction of the body are automatically performed on the infrared image with the help of the additional color and depth information collected by the RGB-D sensor. Automated analysis of the temperature distribution over the entire abdominal region minimizes interference from manual intervention and facilitates operation in a clinical environment. An experimental comparison of temperature distribution in normal babies and those with NEC demonstrates encouraging initial results.","PeriodicalId":152478,"journal":{"name":"2020 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131336135","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}

Various methodologies often do not account for potential errors in arterial pressure and diameter measurements. This paper highlights these pitfalls through the design and instrumentation of a bi-modal probe integrated with A-scan ultrasound and force sensor. This probe is used for simultaneous and single-site assessment of pressure – diameter (PD) loop of superficial arteries. In-vivo measurement of PD loop is a gateway to study the mechanical properties of artery, design and development of vascular grafts and clinically significant for measurement of arterial stiffness, local pulse wave velocity, and central blood pressure. The novelty comes with the usage of an image free A-scan mode of ultrasound, which makes it possible to keep the force sensor and ultrasound transducers very close, solving one of the challenges faced by state-of-the-art techniques in single site measurement. In addition to this, in-house-developed acquisition hardware and software ensures matched frequency response and time synchronization for both pressure and diameter signals. Signals were reliably recorded with an SNR of 20 dB and constructed PD loop is in the clockwise direction with pressure signals leading diameter signals.","PeriodicalId":152478,"journal":{"name":"2020 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131356702","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}

One of motor symptoms is freezing of gait (FoG) that consists in a few seconds during which patients can't start to walk again. In this paper 41 patients affected by PD, with and without FoG, underwent gait analysis performing three gait tasks: normal gait, a motor dual task and a cognitive task. A statistical analysis was performed on clinical, demographical and on the spatial and temporal parameters in order to find any difference between PD patients with and without FoG; the last one obtained no statistically significant results. Thus, a machine learning analysis was implemented employing tree-based algorithms (decision tree, Random Forests, Gradient Boosted Tree, Ada-Boosting of a decision tree) and using as input the spatial and temporal features of gait. The results were promising since accuracy, specificity and sensitivity overcame 90%, reaching also 100% of sensitivity in some cases. The best algorithms were Gradient Boosted Tree and the Ada-Boosting of a decision tree while Random Forests and decision tree obtained lower results. This study proved that machine learning can help to identify patients affected by mild form of FoG that exposes them to a major risk of developing more severe form of freezing with a consequent increased risk of falling.","PeriodicalId":152478,"journal":{"name":"2020 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132706370","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}

In the present work, ETS algorithm has been used in the post-processing phase firstly to reconstruct different sine waveforms generated through an in-house mathematical software simulating physiological conditions and secondly to reconstruct a real ECG recording. The uncertainty of the ETS method for all the reconstructions carried on has been estimated by means of Monte Carlo Simulation (MCS).
