“…Augmented reality can be described as live direct or indirect view of a physical real-world environment whose elements are augmented by computer generated sensory input such as sound, video, graphics, or GPS data [1,2,4,5]. One's current perception of reality can be enhanced by the functions of this technology.…”

“…One's current perception of reality can be enhanced by the functions of this technology. Augmented reality is related to a more general concept called mediated reality, in which a computer modifies a view of reality [4,5]. The term of virtual reality is methodologically different from the term of augmented reality.…”

“…The term of virtual reality is methodologically different from the term of augmented reality. Virtual reality completely replaces the real world with a simulated one [4][5][6][7]. Augmentation is conventionally in real time and in semantic context with environmental elements.…”

“…The preoperative neuro-radiological images can be transferred into the computer memory to use as the source of augmented reality graphics [4][5][6]. The graphic images including the target of the pathology can be projected by using a simple, small and suitable projection machine to the patients' head in the hibrite model of the virtual and real imaging in a single place.…”

“…Navigation by augmented reality using image overlay systems has been introduced in several clinical settings, including neurosurgery, orthopedics, urology, and abdominal surgery, and has shown potential utility in assisting the performance of safe and secure surgical or interventional procedures [13][14][15][16][17][18][19][20][21][22][23]. We recently devised a new medical navigation system that superimposes threedimensional (3D) models onto real-time images taken by the back-camera of a tablet personal computer (PC) [24].…”

Purpose The purpose of this study was to develop and preliminarily test a radiotherapy system for patient posture correction and alignment using mixed reality (MixR) visualization. The write‐up of this work also provides an opportunity to introduce the concepts and technology of MixR for a medical physics audience who may be unfamiliar with the topic. Methods A MixR application was developed for on optical‐see‐through head‐mounted display (HoloLens 2) allowing a user to simultaneously and directly view a patient and a reference hologram derived from their simulation CT scan. The hologram provides a visual reference for the exact posture needed during treatment and is initialized in relation to the origin of a radiotherapy device using marker‐based tracking. The system further provides marker‐less tracking that allows the user tofreely navigate the room as they view and align the patient from various angles. The system was preliminarily tested using both a rigid (pelvis) and nonrigid (female mannequin) anthropomorphic phantom. Each phantom was aligned via hologram and accuracy quantified using CBCT and CT. Results A fully realized system was developed. Rigid registration accuracy was on the order of 3.0 ± 1.5 mm based on the performance of three users repeating alignment five times each. The lateral direction showed the most variability among users and was associated with the largest off‐sets (approximately 2.0 mm). For nonrigid alignment, the MixR setup outperformed a setup based on three‐point alignment and setup photos, the latter of which showed a difference in arm position of 2 cm and a torso roll of 6–7°. Conclusions MixR visualization is a rapidly emerging domain that has the potential to significantly impact the field of medicine. The current application is an illustration of this and highlights the advantages of MixR for patient setup in radiation oncology. The key feature of the system is the way in which it transforms nonrigid registration into rigid registration by providing an efficient, portable, and cost‐effective mechanism for reproducing patient posture without the use of ionizing radiation. Preliminary estimates of registration accuracy indicate clinical viability and form the foundation for further development and clinical testing.
