“…Furthermore, they have proved to be well received by students (Nieder et al, 2000;McNulty et al, 2009). Whether human cadavers have a select advantage over computer-based material is a matter of ongoing debate, however it is clear that both techniques utilise spatial ability and could have the potential to improve individual spatial abilities that are susceptible to change.…”

Spatial ability has been found to be a good predictor of success in learning anatomy.However, little research has explored whether spatial ability can be improved through anatomy education and experience. This study had two aims: 1, to determine if spatial ability is a learned or inherent facet in learning anatomy and 2, to ascertain if there is any difference in spatial ability between experts and novices in anatomy.Fifty participants were indentified: 10 controls, 10 novices, 10 intermediates and 20 experts. Participants completed four computerized spatial ability tasks, a visual mental rotation task, categorical spatial judgment task, metric spatial task and an image-scanning task. The findings revealed that experts (P = 0.007) and intermediates (P = 0.016) were better in the metric spatial task than novices in terms of making more correct spatial judgments. Experts (P = 0.033), intermediates (P = 0.003) and novices (P = 0.004) were better in the categorical spatial task than controls in terms of speed of responses. These results suggest that certain spatial cognitive abilities are especially important and characteristic of work needed in clinical anatomy, and that education and experience contributes to further development of these abilities.

“…This approach permits a better understanding of the features of the specimen by allowing the demonstration of structural details from many angles. 10,11 Melin-Aldana H and Sciortino D found that QTVR movies are also of great potential use in teaching, when it is not possible or practical to maintain an adequate organ "museum," such as a collection of hearts with congenital anomalies and subjects in their study reported more efficient learning of object structure using this interactive technology, compared with using passive observation. They proposed that the use of QTVR technology has an important place in the demonstration of surgical specimens, making a significant contribution to the teaching of anatomic pathology.…”

A comparative study of traditional and digital method in teaching surgical pathology to undergraduate medical students

et al. 2018

Background: During undergraduate medical course surgical pathology is taught on formalin preserved specimens (FPS), a traditional teaching method. These specimens are morphologically altered in color and size due to chemical effect of formalin. Author believe that surgical pathology and disease process can be better understood by digital pictures and videos of surgical procedures. Hence, author did this intervention study to compare the teaching of surgical pathology by traditional method (i.e. Formalin preserved specimen) with digital method.Methods: This prospective study was conducted at Department of Surgery, Himalayan Institute of Medical Sciences, Swami Rama Himalayan University. Final year MBBS (Bachelor of Medicine, Bachelor of Surgery). Students (Four Batches, 20-25 students, n=91) were taught surgical pathology by digital method (per operative and resected specimen pictures/videos) and traditional method (Formalin preserved specimen). Four specimens were taught with cross over i.e. two specimens with help of digital method and two by traditional method. Before start of teaching pretest (Multiple choice Questions, MCQ) was taken and it was followed by post-test (MCQ) for each topic. All teaching was done by single associate professor of surgery. Response of students was assessed by Likert’s scale. Evaluation of the results was done by paired t-test.Results: 94.3% students liked new method of teaching and 90.8% believed that new method leads to better understanding of the subject. In two specimens (Appendix and Gall Bladder) taught by digital method there was statistically significant increase in post test score as compared to FPS method. In specimens (carcinoma colon and breast carcinoma) there was also increase in the post test score though not statistically significant.Conclusions: Digital method was found to be better method for understanding surgical pathology and clinical correlation and should be used to complement traditional method.

“…Any diameter and angle of the structures could be conveniently measured. Various features, such as transparency control, specific object selection, animation, 3D animation as a QuickTime VR (Nieder et al, 2000), and a variety of manipulation modes, made visualization of the complex clp anatomy feasible. However, those attributes were counterbalanced by frequent program hangups.…”

“…The object editor after surface reconstruction (Boissonat, 1988) allowed activation of the nine independent structures, each of which could be individually set in shininess and opacity. Options were rotation-limited to x-and z-directions, like a QuickTime VR (Nieder et al, 2000) object, or free rotation in all three axes, or stereoscopic rotation giving 3D depth when a pair of red/cyan glasses were used. Objects could be visualized either as wire frame, simple box, or as fullframed, with every polygon outlined.…”

Evaluation of two 3D virtual computer reconstructions for comparison of cleft lip and palate to normal fetal microanatomy

et al. 2006

Cleft lip and palate reconstructive surgery requires thorough knowledge of normal and pathological labial, palatal, and velopharyngeal anatomy. This study compared two software algorithms and their 3D virtual anatomical reconstruction because exact 3D micromorphological reconstruction may improve learning, reveal spatial relationships, and provide data for mathematical modeling. Transverse and frontal serial sections of the midface of 18 fetal specimens (11th to 32nd gestational week) were used for two manual segmentation approaches. The first manual segmentation approach used bitmap images and either Windows-based or Mac-based SURFdriver commercial software that allowed manual contour matching, surface generation with average slice thickness, 3D triangulation, and real-time interactive virtual 3D reconstruction viewing. The second manual segmentation approach used tagged image format and platformindependent prototypical SeViSe software developed by one of the authors (F.W.). Distended or compressed structures were dynamically transformed. Registration was automatic but allowed manual correction, such as individual section thickness, surface generation, and interactive virtual 3D real-time viewing. SURFdriver permitted intuitive segmentation, easy manual offset correction, and the reconstruction showed complex spatial relationships in real time. However, frequent software crashes and erroneous landmarks appearing "out of the blue," requiring manual correction, were tedious. Individual section thickness, defined smoothing, and unlimited structure number could not be integrated. The reconstruction remained underdimensioned and not sufficiently accurate for this study's reconstruction problem. SeViSe permitted unlimited structure number, late addition of extra sections, and quantified smoothing and individual slice thickness; however, SeViSe required more elaborate work-up compared to SURFdriver, yet detailed and exact 3D reconstructions were created. © 2006 Wiley-Liss, Inc.Key words: lip anatomy; velopharyngeal anatomy; serial sections; 3D reconstruction; 3D triangulation; SURFdriver; SeViSe; real-time viewingThe key to excellent static and functional results in cleft lip and palate (clp) reconstructive surgery lies in detailed knowledge of the normal and pathological labial, palatal, and velopharyngeal anatomy. The current therapeutic concepts of clp treatment aim at functional reconstruction or imitation of normal anatomy, as expounded by Kriens
