Intraoperative Biomechanical Registration of the Liver: Does the Heterogeneity of the Liver Matter?
Conclusion: As the use of an heterogeneous model does not improve significantly the registration result and increase the computation time we recommend to perform the type of registration task described in the paper with a simplified homogeneous model. Graphical abstract (Source: IRBM)

Spectrophotometry and Photoacoustic Imaging: A Comparative Study
This study aims at comparing absorbance measured by a spectrophotometer and multispectral photoacoustic signals of various coloured phantoms. We compare qualitatively the shape of the spectra obtained, using these two modalities for each sample. Our data suggest that spectrophotometry is a promising way to define reference spectra for classification of multispectral photoacoustic datasets. Graphical abstract (Source: IRBM)

Using Human Factor Cepstral Coefficient on Multiple Types of Voice Recordings for Detecting Patients with Parkinson's Disease
In this study, we wanted to discriminate between two groups of participants (patients with Parkinson's disease and healthy people) by analyzing 3 types of voice recordings. Firstly we collected multiple types of voice recording of three sustained vowels /a/, /o/ and /u/ at a comfortable level which was collected from the 40 participants (20 PD and 20 healthy). The technique used in this study is to extract Human Factor Cepstral Coefficients (HFCC). The extracted HFCC were compressed by calculating their average value in order to get the Voiceprint from each voice recording. Subsequently, a classification method was perform...

Non-invasive Myocardial Shear Wave Elastography Device for Clinical Applications in Cardiology
Conclusion This study presented a new device to evaluate non-invasively myocardial stiffness using an ultrafast ultrasound scanner in a clinical setting. The in-vivo, non-invasive and clinical feasibility was demonstrated showing the potential of the device to evaluate myocardial stiffness accurately up to 25 KPa and for myocardial wall thickness superior to 5-mm.

Four Ethical Issues of “E-Health”
Publication date: Available online 12 September 2017 Source:IRBM Author(s): E. Kleinpeter This communication aims at introducing four ethical issues raised by e-health. The first one is the question of the generation and redefinition of the notion of “health data”, their usage and protection, in the context of the multiplication and decentralization of measure devices. The second one addresses the issue of equality of access to e-health technologies on political and economical grounds and in terms of material and cognitive accessibility. The third question is to determine what is the implicit definitions of the conc...

Local Orientation Imaging for Tissue Structure Using Ultrasound Imaging
Publication date: Available online 5 September 2017 Source:IRBM Author(s): E. Turquin, L. Petrusca, O. Bernard, M. Viallon, H. Liebgott, F. Varray Cardiovascular diseases and myocardium infarction are main causes of death worldwide. After acute myocardium infarction, remodeling occurs within weeks resulting from a loss of cardiomyocytes in the damaged myocardium, and subsequent changes with regional tissue organization. Imaging methods able to render the local tissue directivity would be useful to detect the lesion and evaluate its extent. In this field, diffusion MRI is the reference. However, because of its long ...

Measurement of the Mechanical Properties of the Human Kidney
Publication date: Available online 5 September 2017 Source:IRBM Author(s): A. Karimi, A. Shojaei The kidney plays an important role by filtering of all the blood in the body. Mechanical loading as a result of accident or any kind of trauma can disrupt the normal function of the kidney. Since the abdominal injuries these days are on the rise, understanding the mechanical response of the kidney, as one of the most important organs in the abdomen, is of great interest to design of protective equipment as well as preventive measures. Therefore, the precise reliable mechanical properties of the human kidney are a crucial to...

Lung Segmentation by Cascade Registration
Conclusions The proposed method allows lung segmentation despite the loss of contrast, and can be used to quantify the lung aeration in subjects with ARDS. An improvement in the bottom-most region may be foreseen by combining gray-level based registration and anatomical-landmark matching. Graphical abstract (Source: IRBM)

Relevant Properties for Immobilizing Short Peptides on Biosurfaces
Publication date: Available online 26 July 2017 Source:IRBM Author(s): P. Sevilla, J. Gil, C. Aparicio Understanding protein and oligopeptide adsorption on biomaterial surfaces is important to develop new biomaterials with improved properties. The phenomenon of peptide adsorption is determined by many parameters such environmental pH, surface topographical features, surface polarity, peptide structure, and/or surface and peptide electric charges. We assessed the effect of surface and peptide net charges on oligopeptide adsorption on synthetic surfaces under different conditions. We have also assessed the ability of im...
