Augmented reality technology can enhance people's perception and interactive experience of real scenes due to its characteristics of fusion of virtual and real, and has become a popular technology in the field of computer science. This article mainly studies the application of contrast‐enhanced ultrasound combined with augmented reality medical technology in the treatment of rabbit liver cancer with high‐energy focused knife. Sixty healthy male New Zealand white rabbits were used in this study. Seldinger's method was used to superselective embolize the artery supplying tumor with the help of hepatic angiography, which can kill tumor cells to the greatest extent and reduce the damage to normal liver cells. At the same time, another assistant under the guidance of ultrasound inserted the temperature probe into the position 1 cm away from the microwave radiation source, and then started the microwave ablation (MWA) treatment. High intensity focused ultrasound (HIFU) treatment is carried out under general anesthesia, the breathing rhythm of patients is controlled by ventilator, the proper position is set before operation, the real‐time monitoring is carried out by ultrasound monitoring mediated by medium water, and the HIFU three‐dimensional scanning treatment system is used to accurately cover all tumor treatment areas from point to line and from line to surface, so as to kill tumor cells to the greatest extent. The data of each group were processed by SPSS17.0 statistical software, and the measurement data were expressed as mean ± SD. ANOVA analysis of variance was used to compare the differences among the groups, and LSD method was used to make pairwise comparison within the group. p < 0.05 was considered as having statistical difference. The growth rate of tumor was 56.1% and 60.3%, respectively. Contrast‐enhanced ultrasound combined with augmented reality medical technology provides a new way for the treatment of rabbit liver cancer. [ABSTRACT FROM AUTHOR]

Augmented Reality (AR) sandtables facilitate the shaping of sand to form a surface that is transformed into a digital terrain map which is projected back onto the sand. Although a mature technology, there are still few instances of sandtables being used in surface analysis. Fundamentally there has not been any reported formal assessment of how well sandtables perform in an educational context compared to other conventional learning environments. We compared learning outcomes from using an AR sandtable versus a conventional 3D GIS to convey key concepts in terrain and hydrological analyses via usability and knowledge testing. Overall results from students at a research-intensive New Zealand university reveal a faster task performance and more learning satisfaction when using the sandtable to undertake experimental tasks. Effectiveness and knowledge quiz results revealed no significant difference between the technologies though there was a trend for more accurate answers with 3D GIS tasks. Student learning wise, the sandtable integrated core concepts (especially morphometry) more effectively though both technologies were otherwise similar. We conclude that sandtables have high potential in geospatial teaching, fostering accessible and engaging means of introducing terrain and hydrological concepts, prior to undertaking a more accurate and precise surface analysis with 3D GIS.

Purpose:New rehabilitation strategies for post-stroke upper limb rehabilitation employing visual stimulation show promising results, however, cost-efficient and clinically feasible ways to provide these interventions are still lacking. An integral step is to translate recent technological advances, such as in virtual and augmented reality, into therapeutic practice to improve outcomes for patients. This requires research on the adaptation of the technology for clinical use as well as on the appropriate guidelines and protocols for sustainable integration into therapeutic routines. Here, we present and evaluate a novel and affordable augmented reality system (Augmented Reflection Technology, ART) in combination with a validated mirror therapy protocol for upper limb rehabilitation after stroke. Method:We evaluated components of the therapeutic intervention, from the patients’ and the therapists’ points of view in a clinical feasibility study at a rehabilitation centre. We also assessed the integration of ART as an adjunct therapy for the clinical rehabilitation of subacute patients at two different hospitals. Results:The results showed that the combination and application of theBerlin Protocol for Mirror Therapytogether with ART was feasible for clinical use. This combination was integrated into the therapeutic plan of subacute stroke patients at the two clinical locations where the second part of this research was conducted. Conclusions:Our findings pave the way for using technology to provide mirror therapy in clinical settings and show potential for the more effective use of inpatient time and enhanced recoveries for patients. Implications for RehabilitationComputerised Mirror Therapy is feasible for clinical useAugmented Reflection Technology can be integrated as an adjunctive therapeutic intervention for subacute stroke patients in an inpatient settingVirtual Rehabilitation devices such as Augmented Reflection Technology have considerable potential to enhance stroke rehabilitation [ABSTRACT FROM PUBLISHER]
