This paper presents a method for geometrical and time-delay auto-calibration of an ultrasonic computed tomography (USCT) system. The algorithms used for the calibration are based on the principles similar to the global positioning system (GPS) navigation. Ultrasonic transmitters and receivers in USCT can be viewed like satellite transmitters and mobile receiver units in GPS. However, unlike in GPS, none of the positions of the transmitters or receivers in USCT are assumed to be known and all are the to-be-calibrated unknowns. The presented method is capable of calibrating the positions of all ultrasonic transducers and their individual time delays at once. No calibration phantoms are necessary.

Formalizace lékařských doporučení pomocí obecného grafického GLIF modelu je prezentována na formalizovaných Evropských doporučeních pro prevenci kardiovaskulárních chorob v klinické praxi z roku 2003 a Evropských (ESH/ESC) hypertenzních doporučeních z roku 2003 (HLD). Model vede uživatele rozhodovacími algoritmy pro diagnostiku několika chorob, stanovení celkového kardiovaskulárního rizika a výběr příslušné léčby. Navíc může ukázat jak základní informaci, tak příslušnou část kompletního textu lékařských doporučení (LD), která se týká vybraného elementu GLIF modelu. Formalizace LD lze použít jako zpětné vazby pro autory k odstranění nejasností a informačních nekonzistencí LD. Stanovení celkového kardiovaskulárního rizika a výběr lékové třídy je snažší ve srovnání s časově náročnou manipulací s tabulkami papírových LD. Lékářům nabízí systém pro podporu rozhodování a kontroluje jejich rozhodovací algoritmy ve srovnání s algoritmy LD. V budoucnosti by mohl sloužit jako nástroj pro audit práce lékařů jejich odbornou společností především jako automatický systém s přímou extrakcí dat ze strukturovaného zdravotního záznamu. Počítačová prezentace LD má potenciál pro snažší implementaci znalostí LD než klasická papírová forma LD, a může tak zlepšit primární péči u kardiovaskulárních chorob.

Formalization of medical guidelines by means of a general GLIF graphic model is demonstrated in the formalized 2003 European Guidelines on Cardiovascular Disease Prevention and 2003 ESH/ESC Hypertension Guidelines. It leads a user through the decision algorithm in diagnostics of several diseases, total cardiovascular risk estimation and appropriate treatment. Moreover, it can show both the basic information and the appropriate part of guidelines (GL) complete text concerning the selected GLIF model element. The formalization of GL can function as a feedback for authors to remove uncertainties and information inconsistencies in GL. Estimation of the total cardiovascular risk and selection of a drug class is easier compared to a time consuming manipulation with tables of paper guidelines. It offers to physicians a system for a decision support and it checks their decision algorithms in comparison with those of GL. It could serve as a tool for an audit of physicians work by their professional society using the automatic system, preferably with a direct data access from a structured electronic health record in future. Computer GL presentation has the potential for an easier GL knowledge implementation than the classical paper GL form and thus to improve the primary care of cardiovascular diseases.

Advanced mathematical and deep learning (DL) algorithms have recently played a crucial role in diagnosing medical parameters and diseases. One of these areas that need to be more focused on is dentistry. This is why creating digital twins of dental issues in the metaverse is a practical and effective technique to benefit from the immersive characteristics of this technology and adapt the real world of dentistry to the virtual world. These technologies can create virtual facilities and environments for patients, physicians, and researchers to access a variety of medical services. Experiencing an immersive interaction between doctors and patients can be another considerable advantage of these technologies, which can dramatically improve the efficiency of the healthcare system. In addition, offering these amenities through a blockchain system enhances reliability, safety, openness, and the ability to trace data exchange. It also brings about cost savings through improved efficiencies. In this paper, a digital twin of cervical vertebral maturation (CVM), which is a critical factor in a wide range of dental surgery, within a blockchain-based metaverse platform is designed and implemented. A DL method has been used to create an automated diagnosis process for the upcoming CVM images in the proposed platform. This method includes MobileNetV2, a mobile architecture that improves the performance of mobile models in multiple tasks and benchmarks. The proposed technique of digital twinning is simple, fast, and suitable for physicians and medical specialists, as well as for adapting to the Internet of Medical Things (IoMT) due to its low latency and computing costs. One of the important contributions of the current study is to use of DL-based computer vision as a real-time measurement method so that the proposed digital twin does not require additional sensors. Furthermore, a comprehensive conceptual framework for creating digital twins of CVM based on MobileNetV2 within a blockchain ecosystem has been designed and implemented, showing the applicability and suitability of the introduced approach. The high performance of the proposed model on a collected small dataset demonstrates that low-cost deep learning can be used for diagnosis, anomaly detection, better design, and many more applications of the upcoming digital representations. In addition, this study shows how digital twins can be performed and developed for dental issues with the lowest hardware infrastructures, reducing the costs of diagnosis and treatment for patients.

BACKGROUND: Medical Faculties Network (MEFANET) has established itself as the authority for setting standards for medical educators in the Czech Republic and Slovakia, 2 independent countries with similar languages that once comprised a federation and that still retain the same curricular structure for medical education. One of the basic goals of the network is to advance medical teaching and learning with the use of modern information and communication technologies. OBJECTIVE: We present the education portal AKUTNE.CZ as an important part of the MEFANET's content. Our focus is primarily on simulation-based tools for teaching and learning acute medicine issues. METHODS: Three fundamental elements of the MEFANET e-publishing system are described: (1) medical disciplines linker, (2) authentication/authorization framework, and (3) multidimensional quality assessment. A new set of tools for technology-enhanced learning have been introduced recently: Sandbox (works in progress), WikiLectures (collaborative content authoring), Moodle-MEFANET (central learning management system), and Serious Games (virtual casuistics and interactive algorithms). The latest development in MEFANET is designed for indexing metadata about simulation-based learning objects, also known as electronic virtual patients or virtual clinical cases. The simulations assume the form of interactive algorithms for teaching and learning acute medicine. An anonymous questionnaire of 10 items was used to explore students' attitudes and interests in using the interactive algorithms as part of their medical or health care studies. Data collection was conducted over 10 days in February 2013. RESULTS: In total, 25 interactive algorithms in the Czech and English languages have been developed and published on the AKUTNE.CZ education portal to allow the users to test and improve their knowledge and skills in the field of acute medicine. In the feedback survey, 62 participants completed the online questionnaire (13.5%) from the total 460 addressed. Positive attitudes toward the interactive algorithms outnumbered negative trends. CONCLUSIONS: The peer-reviewed algorithms were used for conducting problem-based learning sessions in general medicine (first aid, anesthesiology and pain management, emergency medicine) and in nursing (emergency medicine for midwives, obstetric analgesia, and anesthesia for midwifes). The feedback from the survey suggests that the students found the interactive algorithms as effective learning tools, facilitating enhanced knowledge in the field of acute medicine. The interactive algorithms, as a software platform, are open to academic use worldwide. The existing algorithms, in the form of simulation-based learning objects, can be incorporated into any educational website (subject to the approval of the authors).

Rigid structural spine scoliosis of a child and even non progressive congenital scoliosis (e.g. isolated hemivertebra) can be treated by hypercorrective brace in full day regime. The article shows the new type of corrective brace with adjustable force effect. The brace consists of 3 stiff parts connected by joints and telescopes. The parts of brace are made from plastic according to plaster form of child trunk. The joints allow only mutual turning brace parts at frontal plane. The special telescopes were developed which operated with prescribed forces, it means the brace and trunk parts are mutually turned at prescribed moments. The article shows the algorithm for calculation of spine stress state, and spine curve correction for given brace with adjusted telescope forces. The second algorithm calculates the telescope forces for demanded spine curve correction. The computer program can be used for computer aid design of brace forces. The force effect of the new type of brace is demonstrated on a 14 months old boy with congenital scoliosis of lumbar spine (hemivertebra L1 and L3 on the right side). Curvature measured according to Coob was changed after application of this brace from 47.5° to 32.0°.
