Modeling for Plastic and Reconstructive Breast Surgery

چکیده
In this paper, we present the modeling and estimation aspects of a virtual reality system for plastic and reconstructive breast surgery. Our system has two modes, a model creation mode and a model tting mode. The model creation mode allows a surgeon to interactively adjust the shape of a virtual breast by varying key shape variables, analogous to the aesthetic and structural elements surgeons inherently vary manually during breast reconstruction. Our contribution is a set of global deformations with very intuitive parameters that a surgeon can apply to a generic geometric primitive in order to model the breast of his/her patient for pre-operative planning purposes and for communicating this plan to the patient. The model tting mode allows the system to automatically t a generic deformable model to patient speci c three-dimensional breast surface measurements using a physically-based framework. We have tested the accuracy of our technique using both synthetic and real input data with very encouraging results.

Primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of B-Cell origin. The association of anaplastic lymphoma kinase (ALK) negative anaplastic large cell lymphoma (ALCL), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especia...

BACKGROUND Many young women are satisfied with their large breasts but suffer from sagging due to heaviness. In this article we present a novel modification of vertical scar breast reduction based on a special indication. METHODS From January 2006 to May 2012, twenty five individual patients underwent operation using modified technique with superior pedicle and vertical scar. Young women betwee...

متن کاملReconstructive and Oncoplastic Surgery for Giant Phyllodes Tumors: A Single Centre\'s Experience
Phyllodes tumors are biphasic fibroepithelial neoplasms of the breast. While the surgical management of these relatively uncommon tumors has been addressed in the literature, few reports have commented on the surgical approach to tumors greater than ten centimetres in diameter – the giant phyllodes tumor. We report a case of giant breast tumors and discuss the techniques utilized for pre-...
متن کاملVirtual 3-dimensional modeling as a valuable adjunct to aesthetic and reconstructive breast surgery.
Three-dimensional (3D) imaging technology currently is used by various commercial industries as a method for analyzing objects and shapes. Recent work from our group and others offer data to support the use of 3D imaging as a valuable tool in aesthetic and reconstructive breast surgery. We have developed a system for creating 3D breast models that provides clinical data that can help guide surg...
