Soft-tissue Biopsy Technique
The instrument described here consists of a special syringe on which sharp cutting needles of various sizes are mounted. These produce undistorted biopsy specimens. Suction is used only to retain the specimen within the needle, and the cleancut cylinder of tissue is quite unlike that obtained by aspiration. Gillman and Gillman&2 used this principle for their liver biopsy instrument. We have ret...
متن کاملFast Least Square Matching
Least square matching (LSM) is one of the most accurate image matching methods in photogrammetry and remote sensing. The main disadvantage of the LSM is its high computational complexity due to large size of observation equations. To address this problem, in this paper a novel method, called fast least square matching (FLSM) is being presented. The main idea of the proposed FLSM is decreasing t...
متن کاملA meshless Galerkin method with moving least square approximations for infinite elastic solids∗
Combining moving least square approximations and boundary integral equations, a meshless Galerkin method, which is the Galerkin boundary node method (GBNM), for twoand three-dimensional infinite elastic solid mechanics problems with traction boundary conditions is discussed. In this numerical method, the resulting formulation inherits the symmetry and positive definiteness of variational proble...
متن کاملA robust anisotropic hyperelastic formulation for the modelling of soft tissue.
The Holzapfel-Gasser-Ogden (HGO) model for anisotropic hyperelastic behaviour of collagen fibre reinforced materials was initially developed to describe the elastic properties of arterial tissue, but is now used extensively for modelling a variety of soft biological tissues. Such materials can be regarded as incompressible, and when the incompressibility condition is adopted the strain energy Ψ...
متن کاملTechniques for soft tissue management around the implants: a review
Dental implants, as a result of their excellent success rates and advantages over fixed or removable methods, have become the optimal treatment for replacing missing teeth. Surgical and restorative techniques that can reduce the loss of hard and soft tissues that often accompany implant placement are desirable. Achieving an esthetic outcome in tooth replacement and implant treatment requires a...
