BACKGROUND: In the sense of Act No. 123/2000 Coll., as amended (hereinafter referred to as "the Act"), a medical device is understood to be a wide range of resources, especially medical equipment. To implement innovative technologies in practice, it is becoming extremely important to be cost-conscious and effective. The aim of the article is to use an ultrasonographic device case study in a selected hospital to show the possibility of solving the use effectiveness of medical devices. METHODS: Within the first step, a summary of the use of ultrasonographic devices is developed in terms of performance number and time. Also, a summary of all costs for the last 5 years has been created. The analyzed ultrasonographic device set is evaluated in terms of activity indicators, profitability, and Du Pont decomposition. Revenues from the operation of individual instruments and payroll productivity are taken into account. All of this is evaluated in the context of the requirements of the department and the spectrum of ultrasonographic devices. RESULTS: The results show that the economic evaluation of device use efficiency, comparing the requirements of the department and spectrum of the devices, suggests a major revision in use of these devices and savings. CONCLUSION: The new design of the most profitable system differs significantly in the arrangement of individual ultrasonographic devices. The benefit of the study is not just a newly designed organization-specific arrangement, but it can be perceived as a modeling approach that can be used to analyze other sets of medical technology.
BACKGROUND: Using of active cardiac medical devices increases steadily. In Europe, there were 183 implants of ICD and 944 implants of PM, 119 of biventricular ICD and 41 of biventricular PM, all per million inhabitants in 2014. Healthcare environments, including radiotherapy treatment rooms, are considered challenging for these implantable devices. Exposure to radiation may cause the device to experience premature elective replacement indicator, decreased pacing amplitude or pacing inhibition, inappropriate shocks or inhibition of tachyarrhythmia therapy and loss of device function. These impacts may be temporary or permanent. The aim of this study was to evaluate the influence of linear accelerator ionizing radiation dose of 10 Gy on the activity of the biventricular cardioverter-defibrillator in different position in radiation beam. METHODS: Two identical wireless communication devices with all three leads were used for the measurement. Both systems were soused into solution saline and exposed in different position in the beam of linear accelerator per 10 Gy fractions. In comparison of usually used maximum recommended dose of 2 Gy, the radiation doses used in test were five times higher. Using the simultaneous monitoring wireless communication between device and its programmer allowed watching of the devices activities, noise occurrence or drop of biventricular pacing on the programmer screen, observed by local television loop camera. RESULTS: At any device position in radiation beam, there were no influences of the device activity at dose of 10 Gy neither a significant increase of a solution saline temperature in any of the measured positions of CRT-D systems in linear accelerator. CONCLUSIONS: The results of the study indicated, that the recommendation dose for treating the patients with implantable devices are too conservative and the risk of device failure is not so high. The systems can easily withstand the dose fractions of tens Gy, which would allow current single-dose-procedure treatment in radiation therapy. Even though the process of the random alteration of device memory and electrical components by scatter particles not allowed to specify a safe dose during ionizing radiation, this study showed that the safe limit are above the today used dose fractions.

More and more scanners of movement and position are used in biomedicine. Number of these scanners is increasing continually, so there is an idea to integrate monitoring of actimetry and ECG. By analyzing these two important signals, especially verifi cation of their relationship we can fi nd a wide use in the systems of home care, but also in diagnostics of various heart diseases.
