The RAS/EMBS International Conference on Biomedical Robotics and Biomechatronics - BioRob 2018 - is a joint effort of the two IEEE Societies of Robotics and Automation - RAS - and Engineering in Medicine and Biology - EMBS.BioRob covers both theoretical and experimental challenges posed by the application of robotics and mechatronics in medicine and biology. The primary focus of Biorobotics is to analyze biological systems from a "biomechatronic" point of view, trying to understand the scientific and engineering principles underlying their extraordinary performance. This profound understanding of how biological systems work, behave and interact can be used for two main objectives: to guide the design and fabrication of novel, high performance bio-inspired machines and systems for many different applications; and to develop novel nano, micro-, macro- devices that can act upon, substitute parts of, and assist human beings in prevention, diagnosis, surgery, prosthetics, rehabilitation.
Broad coverage of concepts and methods of the physical and engineering sciences applied in biology and medicine, ranging from formalized mathematical theory through experimental science and technological development to practical clinical applications.
Microwave theory, techniques, and applications as they relate to components, devices, circuits, and systems involving the generation, transmission, and detection of microwaves.

A computer-based statistical pattern recognition program from digitized spectral waveform envelopes of amniotic fluid displacement during fetal 'respiration'' was developed to extract discriminant features of respiratory maturation. The accuracy of the model reached 98% in estimating maturity in 37 healthy controls. A subset of high-risk subjects was classified with 100% accuracy in relation to maturity and growth. The incorporation of ...

Ultrasound images obtained with a simple linear or sector scan show a granular appearance, called "speckle." This speckle is analyzed. The reduction in speckle that can be obtained with a compound scan with maximum amplitude writing is computed. The reduction in speckle is almost as large as can be obtained with averaging. It depends on the number of independent amplitude ...

The natural observation was conducted on a female baby named as Sunshine during one year from her birth. The results indicated that she showed the preference for the environment similar to maternal womb in typical situations of feeding, sleeping, and bathing. Based on this, the paper proposed the hypothesis that, the initial attachment of infant might be the attachment to ...
A computer-based statistical pattern recognition program from digitized spectral waveform envelopes of amniotic fluid displacement during fetal 'respiration'' was developed to extract discriminant features of respiratory maturation. The accuracy of the model reached 98% in estimating maturity in 37 healthy controls. A subset of high-risk subjects was classified with 100% accuracy in relation to maturity and growth. The incorporation of computer algorithms to extract significant kinematic variables (p < ,05) using pattern-based recognition of spectral signal features may provide a method to classify respiratory-related maturation in medical practice and obtain objective clinical indices of abnormal pulmonary states
Ultrasound images obtained with a simple linear or sector scan show a granular appearance, called "speckle." This speckle is analyzed. The reduction in speckle that can be obtained with a compound scan with maximum amplitude writing is computed. The reduction in speckle is almost as large as can be obtained with averaging. It depends on the number of independent amplitude values that are measured. The condition for the independence of two amplitude values is derived, and thus a limit is given for the possible reduction in speckle.
This paper we present a new design of hollow out of plane titanium microneedle array for aminioic fluid extraction. The structural analyses have been made to determine the mechanical strength of microneedle array. The analysis has involved simulation of three-dimensional model of microneedle array. This analysis predicts the deformation when bending and axial loads are applied to the needle. Successful penetration into skin was verified by measuring the insertion force of the microneedle. The lumen region is made hollow such that the fluid extraction is more reliable than the tapered needle. The extracted amniotic fluid is used for analysis of down syndrome in the fetus. This needle is more reliable than the normal hypodermic needle which has less insertion pain, skin clogging effect is less, no blood loss and safe procedure for the mother and the fetus. This microneedle is designed and simulated using COMSOL Multi physics simulation software.
The natural observation was conducted on a female baby named as Sunshine during one year from her birth. The results indicated that she showed the preference for the environment similar to maternal womb in typical situations of feeding, sleeping, and bathing. Based on this, the paper proposed the hypothesis that, the initial attachment of infant might be the attachment to maternal womb, and it might extend as emotional attachment of the infant after birth.
The power spectrum of acoustic A-mode backscattering was used to determine size of small scatterers. Mean acoustic size of scatterers and histological measurement of mean alveolar sac size were determined from alveolar regions of the normal preterm lamb lung. Comparisons between these date showed no statistical difference (/spl alpha/=0.05, p value=0.144), and suggested that A-mode ultrasound could provide important information about the anatomical changes of the developing alveolus.
A number of utilities should be delivered to householders to fulfil certain requirements via disparate infrastructures associated with production, distribution and consumption. Since the major of these utilities require enormous expenditure and bring complexity, undesired interactions and difficulty in installation, maintenance and management are always encountered. To deal with these issues, a number of models for the single-utility product have been proposed such as the blood of city and the umbilical cording vision. In this study, we propose a model by drawing an analogy between a womb and home so as to supply all services through one utility product. To form the mental picture of the analogy, the life cycle from the birth to the death are taken into consideration in four aspects: foetus as the householder, placenta as the security, umbilical cording as the networking, and amniotic fluid as the stabilizer of the indoor temperature.
In recent years near-infrared optical tomographic imaging (OTI) has made big strides towards becoming a clinically relevant medical imaging modality. Imaging of dynamic changes in blood parameters, functional brain imaging, and breast imaging are the most advanced areas of application of this novel technique. In this study we focus on difficulties that are encountered when OTI is employed for imaging tissues that contain fluid-filled regions. Examples of such tissues are the brain, which contains low scattering cerebrospinal fluids, joints, which enclose translucent synovial fluids, and the maternal abdomen, which is filled with amniotic fluid. In these cases widely accepted image reconstruction schemes that rely on the diffusion approximation have limited applicability, and more advanced model-based iterative image reconstructions methods that make use of the equation of radiative transfer promise more accurate results.
Sepsis is one of the most common disease of mortality during neonatal period, especially infected by Listeria monocytogene (LM). If organisms were acquired in uterus, sepsis can lead to serious septicemia with a higher mortality than acquired after birth. Clinical datas were collected in 9 cases who suffered from sepsis caused by LM Following characteristics of the LM infection were summarized. such as: Pregnancy history: Mother has symptom of infection such as chills, fever. Turbid amniotic fluid and fetal distress in uterus, the neonates have fever, dyspnea, rash, hepatosplenomegaly, seizure, Most cases white blood cell count is elevated, but in cases where white blood cell count is below 5×109/L always indicated serious infection. Blood culture and CSF test should be done as routine test, correct medicine should be choose by Neonatologists in order to found the neonates accorded with meningitis.
A numerical model is used to investigate finite amplitude ultrasound propagation through multiple layers of tissue-like media. This model uses a finite difference method to solve the nonlinear parabolic KZK wave equation. The code is modified to include an arbitrary frequency dependence of absorption and transmission effects for wave propagation across a plane interface at normal incidence. Measurements are taken of the axial nonlinear pressure field generated from a circular focused, 2.25 MHz source, through single- and multiple-layered tissue mimicking fluids. Two tissue mimicking fluids are developed to show acoustic properties similar to amniotic fluid and a typical soft tissue. The measured values of the nonlinearity parameter sound velocity and frequency dependence of absorption for both fluids are presented. These acoustic parameters, in addition to the measurement of the source conditions, are input to the numerical model allowing the experimental conditions to be simulated. Comparisons are made between the model predictions and the axial pressure field measurements. Results are presented in the frequency domain showing the fundamental and three subsequent harmonic amplitudes on axis, as a function of axial distance. The results show that significant nonlinear distortion can occur through media with characteristics typical of tissue. Excellent agreement is found between theory and experiment indicating that the model can be used to predict nonlinear ultrasound propagation through multiple layers of tissue-like media.
