A 3D Telepresence system allows users to interact with each other in a virtual, mixed, or augmented reality (VR, MR, AR) environment, creating shared space for collaboration and communication. There are two main methods representing within these environments. Users can be represented either as point cloud reconstruction-based avatars that resemble physical user virtual character-based controlled by tracking the users' body motion. This work compares both techniques identify differences...

When two or more users attempt to collaborate in the same space with Augmented Reality, they often encounter conflicting intentions regarding occupation of working area and self-positioning around such without mutual interference. Reality is a powerful tool for communicating ideas during co-assisting task that requires multi-disciplinary expertise. To relax constraint physical co-location, we propose concept Duplicated where digital copy 3D region interest users' environment reconstructed...

Background Gait and balance impairments are common in neurological diseases, including stroke, negatively affect patients’ quality of life. Improving gait among the main goals rehabilitation. Rehabilitation is mainly performed clinics, which lack context specificity; therefore, training patient’s home environment preferable. In last decade, developed rehabilitation technologies such as virtual reality augmented (AR) have enabled outside clinics. Here, we propose a new method for persons who...

Three decades after the first set of work on Medical Augmented Reality (MAR) was presented to international community, and ten years deployment MAR solutions into operating rooms, its exact definition, basic components, systematic design, validation still lack a detailed discussion. This paper defines components any (AR) solution extends them exemplary Systems (MARS). We use some original MARS applications developed at Chair for Computer Aided Procedures deployed medical schools teaching...

ABSTRACT While immune checkpoint inhibitor (ICI) therapies are effective treatments for many cancers, ICI associated with immune-related adverse events. We present a 67-year-old man non–small cell lung carcinoma, who developed severe dysphagia biopsies from an esophagogastroduodenoscopy showing histopathology consistent eosinophilic esophagitis while on maintenance therapy pembrolizumab. The patient's symptoms worsened despite standard therapy. However, he had complete resolution of once...

Left-right confusion occurs across the entire population and refers to an impeded ability distinguish between left right. In medicine this phenomenon is particularly relevant as right are always defined with respect patient's point of view, i.e. doctor's left. Traditional anatomy learning resources such illustrations in textbooks naturally consider by consistently depicting a patient seen observer standing front. Augmented Reality Magic Mirrors (MM) one example novel teaching show user's...

When users create hand-drawn annotations in Virtual Reality they often reach their physical limits terms of precision, especially if the region to be annotated is small. One intuitive solution employs magnification beyond natural scale. However, scaling whole environment results wrong assumptions about coherence between and virtual space. In this paper, we introduce Mag-noramas, a novel interaction method for selecting extracting interest that user can subsequently scale transform inside Our...

Intensive care units (ICUs) that host patients infected by the SARS-CoV-2 Coronavirus are separated from other units. In regular ICU ward rounds, a number of experts different medical areas and expertise present to discuss situation patient. However, this procedure is contrasting COVID-19 measures such as reduced contact personnel traffic. project, we demonstrate system for mixed reality (MR) teleconsultation support wards (ARTEKMED). Through ARTEKMED, remote can join local 3D reconstructed...

Anatomy education is an indispensable part of medical training, but traditional methods face challenges like limited resources for dissection in large classes and difficulties understanding 2D anatomy textbooks. Advanced technologies, such as 3D visualization augmented reality (AR), are transforming learning. This paper presents two in-house solutions that use handheld tablets or screen-based AR to visualize models with informative labels in-situ visualizations the muscle anatomy. To assess...

A recurrent problem in egocentric Augmented Reality (AR) applications is the misestimation of depth. Providing alternative views from non-egocentric perspectives can convey useful information for that require correct judgment depth as it case placement and alignment virtual real content, but also exploration visualization tasks.In this paper, we introduce Mirrors. Through integration a mirror, our approach capable to reflect changes content an AR application while users benefit perceptual...

Abstract Objectives Due to the coronavirus disease 2019 (Covid-19) pandemic, all scientific conferences in year 2020 had be adapted their form of presence accommodate for safety regulations, postponed, or canceled entirely. As organizers annual Computer Assisted Radiology & Surgery International Conference Exhibition (CARS)-Conference 2020, we decided hold a “hybrid” conference, i.e., virtual conference with partial mitigate drawbacks purely conference. It is purpose this paper describe...

Fluoroscopic X-ray guidance is a cornerstone for percutaneous orthopaedic surgical procedures. However, two-dimensional observations of the three-dimensional anatomy suffer from effects projective simplification. Consequently, many images various orientations need to be acquired surgeon accurately assess spatial relations between patient's and tools. In this paper, we present an on-the-fly support system that provides using augmented reality can used in quasi-unprepared operating rooms. The...

Current teleconsultation solutions for preclinical emergencies can transmit knowledge from a remote expert to local paramedic using audio and 2D video channels. Such technology lacks precision efficiency medical diagnostic tasks, visual feedback is often missing between participants. We investigate mixed reality 3D solution use, which provides reconstruction of the scene expert, displayed in Virtual Reality. A join virtually as an Augmented Reality avatar. The annotate guide paramedics...

Medical teleconsultation was among the initial use cases for early telepresence research projects since medical treatment often requires timely intervention by highly specialized experts. When remote experts support interventions, a holistic view of surgical site can increase situation awareness and improve team communication. A possible solution is concept immersive telepresence, where users virtually join operating theater that transmitted based on real-time reconstruction local site....

Enabling collaborative telepresence in healthcare, especially surgical procedures, presents a critical challenge. The decompressive craniotomy procedure stands out as particularly complex and time-sensitive. current teleconsultation approach relies on 2D color cameras, often offering only fixed view limited visual capabilities between experts surgeons. However, can be addressed with Mixed Reality immersive technology to potentially enable better consultation of the procedure. We conducted an...

Patients with Cystic Fibrosis related diabetes [CFRD] are treated insulin and high calorie diets to maintain body mass.

Purpose: Image guidance is crucial for the success of many interventions. Images are displayed on designated monitors that cannot be positioned optimally due to sterility and spatial constraints. This indirect visualization causes potential occlusion, hinders hand-eye coordination, leads increased procedure duration surgeon load. Methods: We propose a virtual monitor system displays medical images in mixed reality using optical see-through head-mounted displays. The streams high-resolution...

Magnetically steerable robotic catheters (MSRC) are a promising technology for percutaneous endovascular intervention (PEI) procedures to treat peripheral arterial diseases (PAD), where magnetic actuation is used steer the catheter tip during navigation. However, today's MSRC systems require fluoroscopic imaging location sensing procedure, which risks creating radiation-induced injuries both patient and radiologist. Aiming reduce duration of x-ray radiation in interventions using MSRCs, this...
