Quicktime virtual reality technology in light microscopy to support medical education in pathology

QuickTime virtual reality (QTVR) is a software technology that creates, on a normal computer screen, the illusion of holding and turning a three-dimensional object. QTVR is a practical photo-realistic virtual reality technology that is easily implemented on any current personal computer or via the Internet with no special hardware requirements. Because of its ability to present dynamic photo-quality images, we reasoned that QTVR can provide a more realistic presentation of anatomic structure than two-dimensional atlas pictures and facilitate study of specimens outside the dissection lab. We created QTVR objects, using portions of the skull, and incorporated them into an instructional program for first-year medical students. To obtain images, the bones of the skull were mounted on a rotating table, and a digital camera was positioned on a swinging arm so that the focal point remained coincident with the rotational center of the object as the camera was panned through a vertical arc. Digital images were captured at intervals of 10 degrees rotation of the object (horizontal pan). The camera was then swung through an arc with additional horizontal pan sequences taken at 10 degrees intervals of vertical pan. The images were edited to place the object on a solid black background, then assembled into a linear QuickTime movie. The linear movie was processed to yield a QTVR object movie that can be manipulated on vertical and horizontal axes using the mouse. QTVR movies were incorporated into an interactive environment that provided labeling, links to text-based information and self-testing capabilities. This program, Yorick-the VR Skull, has been used in our first-year medical and graduate gross anatomy courses for the past two years. Results of student evaluation of the program indicate that this QTVR-based program is an effective learning tool that is well received by students.

Introduction. Virtual Reality (VR) is an interactive-immersive, computer-generated environment or experience that may be estimated as the evolution of existing communication interfaces towards different levels of immersion. Over the past 15 years, VR and AR technologies have been actively introduced into clinical medicine. Children are the most active users of modern gadgets and the Internet, so their compliance with new technology is considered the highest. The purpose. To demonstrate the virtual reality (VR) technologies potential in pediatric practice. Materials and methods. For the review, foreign and domestic publications from 2016 to 2023 were used. An analysis of the VR potential in pediatrics was carried out, its positive effects were identified, as well as unresolved issues both on the part of patients and the scientific and clinical community. Results. The pediatrics niches that are likely to be occupied by VR in the future are in the field of rehabilitation, habilitation, psychiatry, and palliative medicine. It is possible to use VR technologies to enhance pain relief, reduce anxiety, depression in almost all subspecialties of pediatrics. Due to its non-invasiveness, the possibility of combining with pharmacological methods, a high degree of empathy and compliance on the part of pediatric patients is ensured. It is also important to ensure epidemiological safety, which has become very popular during a pandemic. Conclusions. The conducted studies and review of scientific publications demonstrate the high potential of VR virtual reality methods in pediatrics. Decreased investment in knowledge-intensive areas, including the use of VR technologies in medicine, may limit their implementation in clinical practice. It is necessary to unite scientific professional communities to conduct randomized clinical trials with the subsequent development of protocols and clinical guidelines for VR in pediatrics.

The application of VR technology in physical education will undoubtedly bring a different experience to school sports activities. However, due to the lack of funds and professionals, it is difficult to carry out VR technology in teaching activities. So we can start from the context setting and use economical means to pave the way for physical education.

Due to improvements in the medical techniques used, virtual reality technologies are increasingly used to treat various diseases. Simultaneously, various ethical issues emerged. Knowing exactly what problems the treating physician and the patient may be facing is important to increase the effectiveness of therapy. This will help minimize or at least prevent negative consequences. A qualitative secondary study was conducted on the ethical issues arising from the application of virtual reality technologies in treatment. Papers suitable for analysis were searched using the keywords virtual reality, ethical issues, and medicine. The works of the last 10 years were selected, most of the sources being at most 5 years old. After analyzing papers and studies which describe the experience of applying virtual reality technologies in medicine, the range of ethical problems that are currently relevant was determined most accurately. Firstly, the vulnerability of patients is evident, which arises from the realism of the avatars and the deep immersion in the virtual world. Without the physicians supervision, the patient may experience a high degree of psychological pressure, which has a negative effect. Secondly, strong emotional involvement is possible, which may develop attachment to the artificial intelligence and cause derealization, depersonalization, and other mental disorders. Thirdly, active interaction with the virtual world may be accompanied by long-lasting effects, such as gaming disorder. Finally, patients may have difficulties in distinguishing between reality and simulation, which affects autonomous choice and compromises informed consent. Virtual reality technologies may potentially change the lives of trauma patients and improve their quality of life. However, these changes are accompanied by ethical issues that must be addressed with respect to the vulnerability and nature of trauma.

Artificial intelligence involves imitating human thought, consciousness, and other aspects. This is similar to having machine with human brain that can think, produce independently. However, unlike human brain, it has a speed, memory advantage. A virtual reality interactive glove is built using a nine-axis inertial sensor, an artificial intelligence deep learning algorithm. In this research work, Product Design Interaction and Experience Based on Virtual Reality Technology (PDIE-VRT-SCGAN) were proposed. Initially, input gestures data are gathered from the Virtual Reality Experiences (VRE) dataset. The input gestures data is then pre-processed using Multi-Window Savitzky-Golay Filter (MWSGF) to reduce noises, increase overall quality of the gestures data. In order to improving overall user engagement in product design interactions on virtual reality (VR) technology, the pre-processed gestures data are then fed into an adversarial network called a Semi-Cycled Generative Adversarial Network (SCGAN). In general, SCGAN does not express some adaption of optimization strategies for determining optimal parameters to promise exact to improving overall user engagement in product design interactions using VR technology. Therefore, FOX-inspired Optimization (FIO) is proposed to enhance weight parameter of SCGAN method, which precisely improving the user experience in product design interaction. The efficacy of PDIE-VRT-SCGAN method is assessed using a number of performance criteria, including tracking accuracy, frame rate, latency, rendering time, error rate, and user error. The proposed PDIE-VRT-SCGAN method attains 22.36%, 25.42% and 18.17% higher tracking accuracy, 21.26%, 15.42% and 19.27% higher latency, 28.36%, 25.32% and 28.27% higher frame rate compared with existing methods, such as design and implementation of virtual reality interactive product software depend on artificial intelligence deep learning algorithm(DVRI-PS-AI-DL), virtual evaluation system for product designing utilizing virtual reality (VES-PD-VR), and analysis of unsatisfying user experiences with unmet psychological needs for virtual reality exergames utilizing deep learning approach (AUUE-UP-VRE-DLA) respectively.
