“…Simulated ablation is also possible using this technology. According to the authors (Harders et al (2005b)), the cutting approach used by this simulator is optimized for their specific application domain and is relatively complex, requiring further work before arbitrary cut paths in 3D are supported. Niederer et al (2009) have also recently developed a hysteroscopy simulator that focuses on accurate simulation of deformation of the uterus.…”

Virtual reality (VR) medical simulations deliver a tailored learning experience that can be standardized, and can cater to different learning styles in ways that cannot be matched by traditional teaching. These simulations also facilitate self-directed learning, allow trainees to develop skills at their own pace and allow unlimited repetition of specific scenarios that enable them to remedy skills deficiencies in a safe environment. A number of simulators have been validated and have shown clear benefits to medical training. However, while graphical realism is high, realistic haptic feedback and interactive tissues are limited for many simulators. This paper reviews the current status and benefits of haptic VR simulation-based medical training for bone and dental surgery, intubation procedures, eye surgery, and minimally invasive and endoscopic surgery.

Hysteroscopic surgery is pivotal in management of many gynecological pathologies. The skills required for performing advanced hysteroscopic surgery (AHS), eg, transcervical hysteroscopic endometrial resection (TCRE), hysteroscopic polypectomy and myomectomy in the management of menorrhagia, hysteroscopic septulysis in fertility-related gynecological problems and hysteroscopic removal of chronically retained products of conception and excision of intramural ectopic pregnancy ought to be practiced by contemporary gynecological surgeons in their day-to-day clinical practice. AHS is a minimally invasive procedure that preserves the uterus in most cases. Whilst the outcome is of paramount importance, proper training should be adopted and followed through so that doctors, nurses, and institutions may deliver the highest standard of patient care.

This article describes a new approach for producing highly realistic visualizations that are interactively cuttable by utilizing the programmability of the graphics rendering pipeline. It combines interactively changing scalar-field derived mesh geometry with static mesh geometry that contains additional lighting terms created offline using three-dimensional modeling software packages. This improves visual realism of surgical simulations whilst enabling more efficient surface representations for interactive areas of the same model, in this case the newly formed surface created when interactively cutting a model. The boundary between the interactively cut surface (generated from the scalar field), and the remaining surface triangles of the static model, is jagged and unrealistic when un-enhanced. Here we describe a method for blending the two models using a simple bleeding effect along the cut edge. This allows the cut edge and the internal cut surface to blend and thereby conceals unrealistic and distracting jagged cut edges. The bloodied edge is more realistic than an unmodified hard edge, which improves the quality of the simulation overall. Moreover, as the available processing power increases the resolution that can be achieved will increase and should allow this method to be extended for slice cutting simulation.
