چکیده مقاله:

Background The use of a medical simulator should enhance the goals of minimally invasive surgery: patient safety, cosmesis, shortening the length of hospital admissions, and reducing cost. Using an innovative approach to the handling of ultrasound images in virtual reality simulation, this article describes a process that employs a hybrid model of deformable models that can be applied in the teaching and practice of oocyte retrieval in infertility programs. MaterialsAndMethods Oocyte aspiration is modeled using a spline mass model by which the collapse of tissue during needle insertion can be modeled using tensor mass models. Organ incision can be modeled using a mass-tensor type model in the incision area and the remainder of the organ can be modeled employing a tensor pre-computation approach. The interface between the two can be designed to comply with the finite element method (FEM)-type method. The displacement of the common nodes shared by both models are hence imposed by the mass-tensor model, which, in turn, receives the resulting forces as its input. Results Analogous to the relationship between robotics and simulation, the present innovation of simulation can be applied to the simulation of ultrasound guided surgeries. Conclusion The goals of laparoscopic surgery will only be achieved if gynecologic surgeons choosing this less invasive approach have the requisite expertise. We believe that the use of this ultrasound deformable model for virtual surgery, will contribute to the attainment of these skills and improved clinical outcomes.

Endoscopic surgery training using virtual reality and deformable tissue simulation

Surgical training systems based on virtual reality (VR) and simulation techniques for tissue deformation may represent a more cost-e!ective and e$cient alternative to traditional training methods. Additionally, VR is a technology that can teach surgeons new procedures and can determine their level of competence before they operate on patients. At Forschungszentrum Karlsruhe (FZK), a virtual rea...

O-10: Assessment of Oocyte and Embryo Quality in Different Time between Oocyte Retrieval and hCG Priming

Background: Abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. In this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (hCG) administration. Materials and Methods: A total of 985 metaphase II were ...

Deformable models for laparoscopic surgery simulation

This paper introduces a method for handling deformation in interactive, real time computer graphics simulations which involve deformable objects and require a high degree of visual realism. Our proposal, the oirrua[ structure, is a “divide and conquer” approach, which combines anovel physical model with a geometric modelling utilizes the theory of elasticity and Newtonian mechanics, applied by ...
