The main characteristic of this technique is the production of a strongly focused acoustic field composed by a near-field and far-field zones, separated by a well-defined focus. Usually, due to the complexity of the vibration of real transducers, this acoustic field is assumed to be produced by a uniform vibrating curved radiator, with a characteristic but unreal acoustic field. If the radiation of the transducer is not uniform, the acoustic field changes importantly. In this paper, we are proposing a technique to characterize the shape of the focused transducers and to measure the radiation distribution very close to the transducer radiating curved surface. The technique uses the electric continuity to detect the position of the transducer surface at each point using a 3D automated positioner (6.4 μm of step resolution). The position is saved, and another measurement is carried out using a hydrophone to measure the pressure at each same point, and obtain the radiating profile. The technique has shown to be appropriate for determining the transducer's shape, with a resolution limited by the positioning system. The pressure radiating profile shown a ring-type behaviors as expected.","PeriodicalId":375152,"journal":{"name":"2018 Global Medical Engineering Physics Exchanges/Pan American Health Care Exchanges (GMEPE/PAHCE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123953871","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}

With the increase of technology and computational storage facilities, usage of Real World Data (RWD) and Big Data Mining (BDM) techniques is proving to be a useful tool for automated data analysis. Entities dealing daily with medical practice such as clinics and hospitals possess databases with a wellspring of information worthwhile being studied to aid clinicians establishing disease patterns identification, future trends, and therapeutic relationships. Aiming at assessing cardiovascular disease (CVD) progression of diabetic patients, a nearly 20 years old private clinic data-base was studied. Primarily goal, and subject of this paper, was the evaluation of the data-base reliability to continue the study of CVD progression. Manual inspection of the database content revealed missing and misleading fields, inconsistency of inputted instrumental data, temporal and user dependency of fields filling, particularly concerning CV data. But, statistics computed on the 20222 diabetic patients' records whose empty entries were eliminated revealed RWD conclusions coherent with published ones.","PeriodicalId":375152,"journal":{"name":"2018 Global Medical Engineering Physics Exchanges/Pan American Health Care Exchanges (GMEPE/PAHCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116345287","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}

Also, healthy feet readings were taken with an industrial thermographic camera and an infrared (IR) thermometer for the comparison of data between the prototype and calibrated equipment. The data were compared to correct the prototype characteristic equation for predict and approximated human skin temperature and search for a thermographic description of the diabetic foot. The difference in infrared energy emitted by the feet is not known. But by the interpretation of the temperature, it was known that the average of the difference between the feet of people with diabetes mellitus and without diabetes is of 4.27 °C for the right foot and 3.39 °C in the left foot. This information was collected with the equipment developed in the laboratory and interpreted with a characteristic equation with 98% correlation.

A general definition of health is explained by the opposite concept of disease. To maintain a healthy state of the individual, a health management protocol based on user's own physiological data is required for individual. In this paper, we propose a protocol for predicting and managing health information of users based on personal physiological history data using linear regression analysis. Subjects were selected for obesity based on BMI, and linear regression analysis was performed between exercise parameters and obesity index according to personal training exercise. Exercise parameters are cumulative exercise distance and exercise days, and obesity parameters are BMI, body fat rate, and body muscle rate. The user can receive feedback on the predicted date that can reach the health information result and actively participate through the gamification function that visually feedbacks the changing health information through the avatar function of the smart device respectively. These protocols will be applied to a personalized health management platform that will prevent disease and maintain a healthy state in the future.","PeriodicalId":375152,"journal":{"name":"2018 Global Medical Engineering Physics Exchanges/Pan American Health Care Exchanges (GMEPE/PAHCE)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121126590","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}

Peculiar acoustic components associated with inspiratory, expiratory, S1 and S2 phases of cardiopulmonary function such as for example asthmatic wheezes serve as useful diagnostic indicators. Supplementing traditional auscultation with automatic detection and categorization of characteristic signals provides opportunities of enhanced long term monitoring which is indispensable in COPD or other cardiac origin abnormalities. Also, due to age related or other sensorial limitations of a health care professional, automatic event detection of LS-HS could significantly enhance these aspects of medical diagnosis. In particular, proposed novel method is based on the elements of VAD (Voice Activity Detection), associated with similar to LS-HS frequency components, and utilization of Gaussian Mixture Models (GMM). The automatic detection with GMM is accompanied by Mel Frequency Cepstral Coefficients (MFCC) and Hilbert transform. This technique allows detecting and classifying peculiar events of LS and HS, and obtain a higher classification rates when compared with other VAD forms. The efficiency classification achieved with parallel Hidden Markov Models (HMM) was 95% for LS and 92% for HS, documenting their viable clinical suitability.","PeriodicalId":375152,"journal":{"name":"2018 Global Medical Engineering Physics Exchanges/Pan American Health Care Exchanges (GMEPE/PAHCE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123106512","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}
