Non-invasive body composition measurement methods aid in the health condition evaluation. Constantly improving, are becoming more and more popular among the specialists. Those methods consist of various imaging techniques and ways for obtaining electrical signals generated by the human body. One of those non-invasive methods, based on the human body impedance is the bioimpedance spectroscopy. The...
The commercial Positron Emission Tomography (PET) scanners use inorganic crystal scintillators for the detection of gamma photons. The Jagiellonian-PET (J-PET) detector exhibits high time resolution due to use of fast plastic scintillators and dedicated electronics circuits. Since the time resolution of PET scanner is influenced by numerous factors, e.g. a type of photomultipliers attached to the...
The purpose of the reported research is the elaboration of the method for construction of the cost-effective whole-body single-bed positron emission tomography scanner enabling simultaneous PET/CT and PET/MR imaging. The Jagiellonian Positron Emission Tomograph (J-PET) is built out of 192 scintillator strips arranged axially in three layers forming a cylindrical diagnostic chamber with the diameter...
The parameters (measurements velocity, pulse transit time) are more often used to for cardiology diagnosis. They are essential for qualifications the arterial stiffness and change blood pressure. Can be useful to detect sleep respiratory events or microarousals. The article proposes two concepts aimed at solving the issue of measuring pulse wave velocity PWV and pulse transit time PTT. The first concept...
The increasing demand for innovative systems, used for monitoring the biomedical parameters and comfortable for the patients, leads to the provision of better and better solutions. This paper presents the latest system design for the measurement of psychophysiological parameters for comprehensive use, developed at the Institute of Medical Technology and Equipment in Zabrze (ITAM), in light of previous...
The article is aimed at presenting the organizational concept of the wireless personal area network (WPAN network) transmitting biomedical data, used in the BioSip system. The network transmits data from recording modules attached to various locations on the subject's body to a collective node (data integrator) while maintaining all the necessary properties, such as low power consumption of the modules,...
The paper presents the idea behind the implementation of the BioSiP system designed for monitoring biomedical parameters and the patient's behaviour, based on the architecture of a measurement module system located on the subject's body. The system could be developed owing to the market launch of new generations of electronic devices combining high functionality, small size and low power consumption...
The aim of the article is presenting what kind of influence an appropriate preparation of entry data in digital image processing has got upon the final results. The authors have presented it on the basis of lack of synchronization between entry data and its influence on the quality criterion Universal Image Quality Index "Q". In the article an algorithm based on correlation has been proposed...
The article presents a problem of impact of digital images' synchronization on readings of objective measures used to assess digital image quality. The authors propose a method of unifying results to ensure correlation of an objective assessment method with subjective ratings. The proposed algorithm is based on the Normalized Mean Square Error analysis (NMSE). The algorithm proposed in the article...
Health monitoring and body area network (BAN) applications require wireless intelligent monitoring devices and information systems. The aim of our research is to propose a prototype of wearable wireless monitoring device optimized to supervising the patient and examine the influence of movement on the heart rate during normal daily activities. Main purpose of the proposed system consists in simultaneous...
