“…Current reports on the use of virtual reality for craniotomy planning are quite promising [2,9,18]. They support our finding that VR-based craniotomy planning may play an important role in the future of minimally invasive neurosurgical operations.…”

“…3,6,11,13) However, these systems require several neuroimaging data sets with or without contrast medium, proprietary software, and computer workstations. The present 3D technique for visualizing complex angioarchitecture with the nearby brain surface in cases of superficial AVM uses only the DICOM data of TOF MR angiography without contrast medium.…”

Direct surgery remains important for the treatment of superficial cerebral arteriovenous malformation (AVM). Surgical planning on the basis of careful analysis from various neuroimaging modalities can aid in resection of superficial AVM with favorable outcome. Three-dimensional (3D) magnetic resonance (MR) imaging reconstructed from time-of-flight (TOF) MR angiography was developed as an adjunctive tool for surgical planning of superficial AVM. 3-T TOF MR imaging without contrast medium was performed preoperatively in patients with superficial AVM. The images were imported into OsiriX imaging software and the 3D reconstructed MR image was produced using the volume rendering method. This 3D MR image could clearly visualize the surface angioarchitecture of the AVM with the surrounding brain on a single image, and clarified feeding arteries including draining veins and the relationship with sulci or fissures surrounding the nidus. 3D MR image of the whole AVM angioarchitecture was also displayed by skeletonization of the surrounding brain. Preoperative 3D MR image corresponded to the intraoperative view. Feeders on the brain surface were easily confirmed and obliterated during surgery, with the aid of the 3D MR images. 3D MR imaging for surgical planning of superficial AVM is simple and noninvasive to perform, enhances intraoperative orientation, and is helpful for successful resection.

“…Consequently, efforts have been made to identify processes in the target delineation process amenable to improvement, such as multimodality image incorporation [8,[17][18][19][20][21][22], instructional modification [23][24][25], visual atlas usage [11-15, 26, 27], window-level adjustment [28], autosegmentation [29,30], and software-assisted contouring [25]. While specialized data entry mechanism for spatial data is common in other arenas (e.g., video games [31] and virtual simulation workstations [32,33]), there have been comparatively few efforts to modify ROI definition at the hardware level in radiotherapy. Previously, ergonomic analysis by Kotani and Horii [2] compared pen-tablet and mouse UIDs, demonstrating improved performance by pen-tablet UID on standardized repetitive computer drawing tasks (e.g., clicking, dragdropping) and polygon tracing.…”

The purpose of this study was the prospective comparison of objective and subjective effects of target volume region of interest (ROI) delineation using mousekeyboard and pen-tablet user input devices (UIDs). The study was designed as a prospective test/retest sequence, with Wilcoxon signed rank test for matchedpair comparison. Twenty-one physician-observers contoured target volume ROIs on four standardized cases (representative of brain, prostate, lung, and head and neck malignancies) twice: once using QWERTY keyboard/scroll-wheel mouse UID and once with pen-tablet UID (DTX2100, Wacom Technology Corporation, Vancouver, WA, USA). Active task time, ROI manipulation task data, and subjective survey data were collected. One hundred twenty-nine target volume ROI sets were collected, with 62 paired pen-tablet/mouse-keyboard sessions. Active contouring time was reduced using the pen-tablet UID, with mean ± SD active contouring time of 26 ±23 min, compared with 32 ± 25 with the mouse (p ≤ 0.01). Subjective estimation of time spent was also reduced from 31 ±26 with mouse to 27 ± 22 min with the pen (p = 0.02). Task analysis showed ROI correction task reduction (p = 0.045) and decreased panning and scrolling tasks (p < 0.01) with the pen-tablet; drawing, window/ level changes, and zoom commands were unchanged (p = n.s.) Volumetric analysis demonstrated no detectable differences in ROI volume nor intra-or inter-observer volumetric coverage. Fifty-two of 62 (84%) users preferred the tablet for each contouring task; 5 of 62 (8%) denoted no preference, and 5 of 62 (8%) chose the mouse interface. The pen-tablet UID reduced active contouring time and reduced correction of ROIs, without substantially altering ROI volume/coverage.
