To investigate if a written guide or augmented reality (AR) guide improves free recall of diversified chiropractic adjusting technique and to capture participants' impressions of the study in a poststudy questionnaire. Thirty-eight chiropractic students were evaluated for diversified listing (a nomenclature denoting vertebral malposition and correction) recall, pre-AR and post-AR, or written guide review. The vertebral segments used were C7 and T6. Two randomized groups reviewed an original course written guide (n = 18) or a new AR guide (n = 20). A Wilcoxon-Mann-Whitney (C7) and t test (T6) compared group differences in reevaluation scores. A poststudy questionnaire was given to capture participants' impressions of the study. Both groups showed no significant differences in free recall scores after reviewing the guides for C7 or T6. The poststudy questionnaire suggested a number of strategies could be used to improve current teaching material such as more detail in the written guides and organizing content into smaller blocks. Use of an AR or written guide does not seem to change participants' free recall ability when used to review diversified technique listings. The poststudy questionnaire was useful to identify strategies to improve currently used teaching material. [ABSTRACT FROM AUTHOR]

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]
