Cardiovascular diseases are the leading cause of global mortality accounting for more than 17 million deaths annually. This represents approximately 30 % of all global mortality with an increasing trend and consequent growth in the use of cardiac imaging systems. Transesophageal echocardiography represents a highly convenient method to diagnose heart pathologies and to monitor cardiac procedures....
A behavior-oriented human-machine communication system based on bio-inspired information processing is developed in this paper. A low cost acoustic interface using microphones is created as an emotional interaction channel for robotic assistants in domestic environments for the care of elderly people with mild cognitive impairment. Classification of communication signals such as striking, petting,...
Transesophageal Echocardiography (TEE) is used to visualize ultrasound heart images for diagnosis or surgery monitoring. The existing TEE is operator dependent and does not provide sufficient safety features to localize the TEE probe tip inside the human body. In order to improve safety in the usage of TEE, a novel technique for TEE probe tip localization has been developed. This technique is based...
There exists growing demand for the improvement of Transesophageal Echocardiography probe control. In order to provide remote control, a Fuzzy Logic based approach is presented. Preliminary results based on MATLAB2014a enclose the simulation of desired motor behavior of 2 Dynamixel MX-28 which actuate ultrasound probe movements. We conclude that the Fuzzy Logic toolbox is highly applicable for simulating...
The quality of ultrasound images highly depends on sonographer skills. This paper describes a platform for the reduction of operator dependency during transabdominal ultrasound examinations. The design includes a linear system to enable automatic transabdominal ultrasonography of the cervix. The system was integrated within APLIO MX SSA-780A TOSHIBA ultrasound machine. Results show operator independent...
There exists an increasing demand of human development support systems in progressive health care. Early Intervention Support System For Special Children (Elissa) is used. It shows limited functionality for activity tracking. In order to counteract this, continuous face tracking based head movement control is developed. The major contribution of this paper lies in the implementation of face tracking...
In this paper, an analysis of the Electroretinography response for both flickering and current stimulations is presented. To perform the analysis, data from 6 subjects was collected. The subjects underwent two types of stimulation: (1) flickering, and (2) current. Electrodes with two different inner diameters (0.4 cm) and (0.7 cm) were used to record retina responses. The configuration of electrode...
A system that determines the correct position of the umbilicus enables the automatic ultrasound diagnosis of the human abdomen. The customization of the diagnosis procedure using personalized scanning is important when it comes to more precise and predictable medical treatment. The setup used here is based on a combination of three linear motors controlled by an ATmega328 microcontroller using real-time...
For the development of clinical care pathways for the Brazilian hospital information system Pajé, a modeling tool is required. For the selection of this tool, some modeling standards were reviewed, applied and subsequently evaluated. Four modeling tools, zOOml, gmodeler, dia and UMLet were tested and validated for the process of modeling UML diagrams based on predefined requirements. Results show...
Temperature measurement in magnetic fields is indispensable for Magnetic Resonance safety studies and for temperature calibrations during Magnetic Resonance applications. A selection of these procedures is subject to the application of MR-compatible robotic systems. The existing problem for the software version NI LabVIEW 2013 is the lack of an instrument to automatically process data from a fiber-optical...
As stated by WHO, around 9.2% of 28 million newborn babies worldwide are stillbirths. Moreover, approximately 358,000 women died in 2008 due to birth complication. Most of these incidents occur in developing countries. Existing telehealth systems are not integrated in rural and remote areas. Midwives in those areas do not get any support by medical specialists during high risk pregnancy situations...
Maternal mortality plays a major role as one negative factor in the context of improvements in developing countries. In the perspective of Wawasan 2020 this paper provides a solution towards the decrease of maternal mortality by presenting an entire prenatal care kit consisting of soft- and hardware. Several published approaches in prenatal care are discussed herein. The difference of our approach...
In order to reduce uncomfortable cervix screening either using Pap smear or transvaginal ultrasound scanning, an autonomous transabdominal ultrasound scanning is proposed. This requires an exact probe position and angulation to capture the cervix image. In this paper, we present a new method to detect cervix in the best position and angulation. More than 100 samples were processed and analyzed. Image...
