This paper introduces the Radial Elements Method – REM for the simulation of deformable objects. The REM was conceived for the real time, dynamic simulation of deformable objects. The method uses a combination of static and dynamic approaches to simulate deformations and dynamics of highly deformable objects. The real time performance of the method and its intrinsic properties of volume conserv...

abstract: objective: giant cell tumor of soft parts is a rare neoplasm that mainly affects adulst and the elderly and is usually located in the extremities. here we report a child with giant cell tumor of soft tissue, which is a very rare condition in childhood. clinical presentation: a 5 year old girl presented with a 5 month history of left lower extremity pain. she had developed paraplegia b...

In this paper, we discuss physically based approaches to the modeling of deformable soft tissue for the long-term prediction of patient’s postoperative appearance in cranio-maxillofacial (CMF) surgery simulations. Since the biomechanical properties of living tissues and their numerical modeling are, in general, very complex, our focus is on the investigation of qualitative and quantitative diff...

Introduction: Fishbone is the most common foreign body found in the oropharynx. Conventionally patients with suspected fishbone in the throat would have mirror laryngoscopy followed by lateral soft tissue X-ray to look for the fishbone or observe impacts caused by the fishbone i.e. soft tissue swelling or air in upper esophagus. However, the most common site of fishbone impact is the suprahyoid...

objective: since orthodontic and orthognathic treatment planningin each ethnic group must be done according to the soft tissue facial characteristicsregarded as beauty,they thus vary from country to country.the main purpose of this articlewas to determine the mean range of the middle third of soft tissue facial profile and anteroposterior lip positioningusing 3angular and 2 linear measurements ...

Background: Laser-tissue interaction on low-level laser therapy (LLLT) has widespread medical applications (e.g., improved wound healing). The tensile strength of radiated tissue by LLLT is known to be increased mainly because of cross collagen bands developed after radiation.Objective: In this work, we studied the instantaneous effect of radiation of polarized laser beam on the viscoelastic ti...

We report here a rare case of lateral ectopia of thyroid without orthotopic thyroid tissue in an Indian teenager, who was referred to our department for a thyroid scintigraphy. Technetium Pertechnetate (99mTcO4- ) scan showed uptake in laterally placed soft tissue structure along with functioning thyroid tissue in high anterior midline neck region in line with thyroglossal...

The aim of our work is to provide maxillofacial surgeons with an integrated osteotomy planning system for complex bone relocations, facilitating a preoperative assessment of functional as well as æsthetic rehabilitation. On this account we try to establish a robust modeling approach based on a histomechanical soft tissue model that reliably predicts the postoperative facial appearance. For two ...

The modeling of grasping and cutting in surgery are two fundamental tasks that must be achieved for the development of a reality-based haptic interface in robot-assisted surgery. Currently, the lack of these models with soft tissue has limited the accuracy of such interfaces in surgery. As a result, we have taken the first steps in realizing soft tissue models through the development of an auto...
