We are particularly interested in examining the problem of aligning CT volumes to corresponding X-ray images. Our objective is to apply the 2D-3D registration in the field of orthopedics, specifically on ankle surgery. The long-term goal of this work is to apply this technique to ankle fusion surgery to determine the proper size and orientation of the screws which are used for fusing the bones together. In addition, we try to localize the best bone region to fix these screws. Our framework adopts the shear-warp factorization method to generate synthetic 2D images from the given 3D volume. Also, the alignment score is determined according to Exponential Correlation (EC) as a new similarity measure. We used a variety of methods to evaluate registration quality of our system. It has been tested on 15 clinical CT datasets. Evaluation results indicate the degree of accuracy of our registration framework.","PeriodicalId":416740,"journal":{"name":"2012 Cairo International Biomedical Engineering Conference (CIBEC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127693126","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 work the authors focus on maintenance activities in developing countries where there is a lack of acquisition planning, assessment, budgeting planning, and critical equipment breakdown. In the past decade there has been an explosion in the use of system dynamics modeling in healthcare. In this paper a system dynamics based model for medical equipment maintenance is designed; it incorporates 8 key variables that influence the progress of medical equipment maintenance. This model shows the effect of changing a key variable on the others. This model is intended to maximize the quality and to minimize the cost and time of medical equipment maintenance. This is developed in a causal loop diagram, which is a cause and effect diagram. iThink software has been used in the development of this model, together with vensim in the development of the causal loop diagram. The results show that the critical variables for maintenance are the defect rate, breakdown rate, and maintenance cost. In conclusion the medical equipment maintenance cost determines the decision for acquiring new equipment. The type and number of equipment to be acquired is determined according to the available budget.","PeriodicalId":416740,"journal":{"name":"2012 Cairo International Biomedical Engineering Conference (CIBEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115462898","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 therapeutic cancer clinical trials, the tumors are measured from medical images such as CT or MR at a baseline time point and the treatment response assessment is followed-up on a frequent basis at subsequent time intervals. In this paper, we will try to evaluate to which degree the measurements from medical images are comparable for clinical trials by specifying sources of uncertainties of image measurements in order to support both clinical trial investigators by giving them confidence in their interpretation of the measurements results and implementers to follow the best-practice guidelines to be taken into consideration to minimize sources of such variability.","PeriodicalId":416740,"journal":{"name":"2012 Cairo International Biomedical Engineering Conference (CIBEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115694133","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}

EEG signals of thirty schizophrenic patients and age-gender matched healthy subjects were recorded from F3 left frontal region and analyzed using wavelet decomposition and Welch power spectral density (PSD) methods. Results show that PSD of all EEG sub-bands in patients was higher than that of control subjects during all periods of the experiment. Moreover, auditory stimuli evoked a significant decrease of Welch PSD of beta activity of EEG data in both groups. However, no significant change was found between stimulation periods in schizophrenia group. This methodology can be used to analyze EEG signals of schizophrenia patients to reach discriminative features between patients and controls.","PeriodicalId":416740,"journal":{"name":"2012 Cairo International Biomedical Engineering Conference (CIBEC)","volume":"290 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116864405","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 robot relies on the hospital WLAN for remote control and transmission of data in both directions between the robot and the control room. Lifting, handling and transporting radioactive materials within the hospital is one of the primary functions carried out by the robot. This function is important to reduce the exposure of hospital staff to harmful radiation. Another function of this robot is audio-visual patient-doctor communication even when the doctor is unable to be physically at the hospital. In case of WLAN failure, the robot can be controlled manually using a joystick. The robot can be easily manufactured at low cost and hence has the potential for commercial production and a wide distribution in local and regional hospitals.","PeriodicalId":416740,"journal":{"name":"2012 Cairo International Biomedical Engineering Conference (CIBEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121273731","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 system analyzes subject's health and fitness features and provides an optimal set of exercise prescriptions. To evaluate subject's health status and for risk stratification, any assessment device can easily communicate with the system as it uses flexible XML based protocols. The system uses hybrid reasoning technique to employ both the experts' knowledge and experience into the system. To validate the system, a comparison between system's prescription outcome and a control dataset is presented along with a case study.","PeriodicalId":416740,"journal":{"name":"2012 Cairo International Biomedical Engineering Conference (CIBEC)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131536468","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}

Cardiac pacemakers can be modeled accurately with relaxation oscillator with some complex changes that make it difficult to tune the model matching with the exact behavior of the cardiac potential generators because of different varying parameters. The proposed model is simple and can easily be tuned with two parameters which make it attractive and useful. The model is based on external forcing function and it is not modeled as self-excited oscillator. The sinusoidal forcing function is applied and its behavior is controlled using two different damping parameters. The results achieved in this way are exactly the same as obtained with the relaxation oscillators. Matlab is used to simulate the model.","PeriodicalId":416740,"journal":{"name":"2012 Cairo International Biomedical Engineering Conference (CIBEC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125185064","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}
