“…Invasive markers are more reliable but confer risk of pain, infection, bleeding and scarring from their fixation to tissue. Systems which can achieve automatic markerless registration with low error are ideal and are the subject of ongoing research including in open, 112,113 laparoscopic 114 and robotic surgery 115 …”

Background This systematic review aims to critically appraise the intraoperative use of augmented and mixed reality technology to improve surgical outcomes. Method A literature search of PubMed, Scopus, Cochrane Central Register of Controlled Trials, http://ClinicalTrials.gov and WHO ICTRP was performed in accordance with Cochrane Handbook for Systematic Reviews of Interventions. Results This review included 94 studies on 2473 patients, comprising 78 studies on augmented reality and 16 on mixed reality. This technology has seen broad intraoperative application. Augmented and mixed reality can reduce operative duration, blood loss, and the duration of inpatient care. Current evidence shows that they achieve this most in percutaneous surgery. Conclusions Augmented and mixed reality technology improve surgical outcomes by increasing navigational speed and reducing navigational error intraoperatively. However, they have technical limitations which are the subject of ongoing research. Further studies are necessary to define how this technology is best applied intraoperatively. Systematic Review Registration: PROSPERO CRD42020205892.

“…In this setting, the group improved the AR technique by implementing hyper-accurate 3D reconstruction technology (HA3D) [32] and further developed a 3D elastic AR system, which allowed simulating the prostate deformation caused by the robotic instruments in the dynamic phase of the surgery and, therefore, to better adapt the imaging overlay during the surgical procedure [31] . Porpiglia et al conducted a prospective study including 40 PCa patients, 20 undergoing 3D AR RARP and 20 undergoing 2D cognitive RARP [33] . In the 3D AR group, capsular involvement was correctly identified in 100% of cases versus 47% in the 2D cognitive group (P < 0.05).…”

“…This barrier was overcome by Porpiglia et al, who described an elastic AR model in 2019. However, all current MRI-based AR systems still have the limitation of requiring manual adjustment of the image by another urologist during surgery [33] . Therefore, the development of new automated models in this field will be necessary.…”

The recent application of novel technologies to the robot-assisted radical prostatectomy (RARP) procedure has provided a new perspective and demonstrated potential usefulness in surgical planning, intraoperative navigation, and education of both patients and healthcare professionals, allowing for a patient-tailored prostate cancer (PCa) treatment. Integration of novel techniques into robotic surgery has improved the accuracy of surgery and has demonstrated a potential benefit in functional and oncological outcomes in patients with PCa. However, further randomized and prospective studies are needed to assess and validate the role of these technologies in clinical practice. The aim of this review is to summarize the current evidence on the new emerging techniques, such as three-dimensional (3D) imaging and printing, augmented reality (AR), and confocal microscopy (CM), and their impact on RARP and its oncological outcomes.

“…MR has long been used to augment a person's sensory capabilities by overlaying medical images or volumetric models in situ for ultrasound-guided needle biopsies [9,10], robot-assisted surgery [11], laparoscopic surgery [12,13], and transcranial magnetic stimulation [14]. Some implementations also include static guides illustrating where to align an instrument [15,16].…”

Purpose: In “human teleoperation” [1], augmented reality (AR) and haptics are used to tightly couple an expert leader to a human follower. To determine the feasibility of human teleoperation, we quantify the abil- ity of humans to track a position and/or force trajectory via AR cues. The human response time, precision, frequency response, and step response were characterized, and several rendering methods were compared. Methods: Volunteers (n=11) performed a series of tasks as the fol- lower in our human teleoperation system. The tasks involved tracking pre-recorded series of motions and forces, each time with a different rendering method. The order of tasks and rendering methods was ran- domized to avoid learning effects and bias. The volunteers then performed a series of frequency response tests and filled out a questionnaire. Results: Rendering the full ultrasound probe as a position target with an error bar displaying force led to the best position and force tracking. Following force and pose simultaneously was more difficult but did not lead to significant performance degradation versus following one at a time. On average, subjects tracked positions, orientations, and forces with rms tracking errors of 6.2 ± 1.9 mm, 5.9 ± 1.9˚, 1.0 ± 0.3 N, steady-state errors of 2.8 ± 2.1 mm, 0.26 ± 0.2 N, and lags of 345.5 ± 87.6 ms respectively. Performance decreased with input frequency, until the person could no longer follow, depending on the input amplitude. Conclusion: This paper characterizes human tracking ability in aug- mented reality human teleoperation, which shows the system’s feasi- bility and good performance, and is important for designing future human computer interfaces using augmented and virtual reality.
