Quarterly published in print and online "Inventi Rapid: Biomedical Engineering" publishes high quality unpublished as well as high impact pre-published research and reviews catering to the needs of researchers and professionals. This multidisciplinary journal covers all recent advances in the field of biomedical technology, instrumentation, and administration. Papers are invited focusing on theoretical and practical problems associated with development of medical technology; introduction of new engineering methods into public health, hospitals and patient care, improvement of diagnosis and therapy, biomedical information storage and retrieval etc.
Fetus facial expression analysis is a recent and upcoming field of study in the area of biomedical image processing. Fetus images are obtained using 3D ultra-sounds. It is one of the important assessments for describing the condition of fetus in womb. The assessment of fetal behavior in different periods of gestation may make possible early diagnosis of various structural or functional abnormalities. Proposed approach is working on 3D fetal images dataset which consists of four steps, namely preprocessing, face detection, facial feature extraction and emotion recognition. This paper describes the study that uses Gabor wavelets for feature extraction and multilayered artificial neural network for classification. The main advantage of the proposed system is that it not only detects facial expression but also improves the Human Computer Interface (HCI) and motivates us to detect and extract different behavior of the baby prior to birth....
The purpose of our study was to analyze the effect of inhomogeneities on dose estimation near an Ir-192 source. Heterogeneity correction factors (HCFs) are calculated using Monte Carlo method and the computed values are compared with the experimentally measured values using ion chamber for different inhomogeneities viz. air, PMMA, polystyrene, water, bone, soft tissue and polysulphone in various phantom conditions viz. in-air, RTPS-PMMA and in-water phantoms. Study reveals that the dose correction factors are of the order of 15 % to 34 %. The agreement between measured and calculated HCFs was found to be within 7 %. The reason for this discrepancy is not clear although it could be related to the geometry of the ion chamber which is 4 cm in diameter and 1.2 cm thick. Hence, it is concluded that the accuracy of dose calculation in brachytherapy and the problem of inhomogeneity correction will become increasingly more important in the future. Further, the Monte Carlo simulation may be used to calculate basic dosimetry data in order to minimizing the dosimetric perturbation arises due to tissue inhomogeneities....
The study was to analyze the dynamic characteristics of ossicular chain under the stimulus frequencies, 125 Hz, 250 Hz, 500 Hz, 750 Hz, 1 kHz, 2 kHz, 3 kHz, 4 kHz, 5 kHz, 6 kHz, 7 kHz and 8 kHz, by finite element method. The finite element model of the ossicular chain of patients could be built by 3D image model of the ossicular chain based on the high resolution computed tomography. The displacement at the footplate would hardly occur when the ossicles was excited by the sound stimuli at frequency above 2 kHz. The presented result shows that the ossicular chain only could transmit the stimuli under 2000 Hz by the vibration of ossicles....
Diseases such as degenerative or rheumatoid arthritis are accompanied by joint destruction. Clinically applied tissue engineering technologies like autologous chondrocyte implantation, matrix assisted chondrocyte implantation, or in situ recruitment of bone marrow mesenchymal stem cells targets the treatment of traumatic defects or of early osteoarthritis. Inflammatory conditions in the joint hamper the application of tissue engineering during chronic joint diseases. Here, most likely, cartilage formation is impaired and engineered neocartilage will be degraded. These developments were underpinned by an earlier revolution in molecular biology and protein engineering as well as key advances in our understanding of rheumatoid arthritis pathogenesis. This review will focus on antibody engineering as the key driver behind our current and developing range of antirheumatic treatments....
