Physiological measurements are necessary for determining parameters of interest. If they deal with indirect measurements, they are not invasive and much more attractive than others. Sweat is a physiological material that can be characterized because its content is useful. It encompasses direct and indirect parameters for measuring health status. One of the parameters is sodium chloride that is an indicator of cystic fibrosis. The main scope of the paper is to illustrate results and findings of designing an acquisition board for conditioning and processing physiological signal containing...

In this paper, the author deals with the advances of electromyographic technique. Nowadays, electromyographic measurements are used in several applications to assess specific pathologies. According to the muscle or myoelectric activity to be monitored, different methodologies have been defined such as, for example, electromyography, electrocardiography, electrogastrography, electroencephalography. Although such techniques require different procedures and instrumentation, each one is based on recording myoelectric signals due to muscle or nerve activity. The analysis of such signals allows...

The main purpose of this work is the assessment of quality performance of medical imaging systems by using objective image quality tests. To this aim, the influence of radiographic parameters has been investigated in order to reduce radiation dose to patients by assuring a good quality of the images.

Stray capacitances, due to e. g. limitations of layout and the use of active circuit elements, lead to limitations of the performance of bioimpedance devices at higher frequencies. The effects of stray capacitances can be avoided by several methods, such as Generalized Impedance Converter (GIC), Negative Impedance Converter (NIC) or external compensating operational amplifier. In this work, the investigation of NIC and GIC for Howland current source shows that both methods are not suitable for multifrequency measurement system, because they need different adjustments of components for every...

An in vitro investigation based on Quantitative Ultrasound (QUS) has been carried out in this paper on a sample of human femoral head, aiming at microstructure characterization and bone quality assessment. Two QUS parameters, Integrated Reflection Coefficient (IRC) and Apparent Integrated Backscatter (AIB) were measured by accurately analyzing ultrasonic signals backscattered from the target bone when immersed in water and insonified at 2.25 MHz. In particular, US data were acquired from 22 different positions along the maximum section perpendicular to the axial direction (head-neck axis) of...

Hip fracture has been recognized as the worst consequence of osteoporosis, as it represents one of the most important causes of disability and mortality in elderly people. An accurate knowledge of the osteoporotic fracture risk in asymptomatic individuals through population mass screenings may be the only way to reduce the occurrence of hip fractures. Aim of this study was to perform a preliminary clinical validation of a new ultrasound (US)- based method for bone densitometry directly applicable on femoral neck. A total of 112 female patients were enrolled for this study (61-75 years of...

The assessment of osteoporotic fracture risk requires the measurement of bone mineral density (BMD) on reference sites (hip and spine) and the evaluation of clinical risk factors (CRFs) for fracture. The Fracture Risk Assessment algorithm (FRAX ®), internationally recognized by official guidelines for osteoporotic patient management, represents a tool for estimating 10-year probability of hip and major fragility fractures by integrating CRFs and femoral neck BMD or T-score, when available. In this work we presented an innovative ultrasound (US)-based method for estimating fracture risk by...

The clinical significance of osteoporosis lies in the relevant occurrence of fractures. Osteoporosis affects about 200 million people in the world and is responsible for 8.9 million fractures each year worldwide. Hip fractures are a major public health burden, from both social and economic point of view, since they represent one of the most important causes of morbidity, disability, decreased quality of life and mortality for the elderly population. It has been demonstrated that bone mineral density (BMD) measurements on lumbar spine or proximal femur, standardly evaluated by dual-energy...

Osteoporosis and overweight/obesity constitute major worldwide public health burdens that are associated with aging. The gold standard for osteoporosis diagnosis is currently represented by bone mineral density (BMD) measurement through dual-energy X-ray absorptiometry (DXA). However, DXA cannot be used for early diagnosis through population mass screenings due to ionizing radiation employment. Because of this, generally, only people considered at high risk of fracture (underweight women after the menopause) undergo to osteoporosis screening. In fact, a significant risk factor for fracture...
