“…Kerdok performed indentation tests on samples of RTV-6166 with and without implanted fiducials and reported that there was no discernible change in its material properties even when using fiducials that had nearly twice the diameter of the ones used in our work [10].…”

“…The tissue phantom was made of GE RTV-6166, the same transparent, homogeneous silicone gel used for the Truth Cube [10]. An experienced brachytherapy surgeon selected this gel as providing more realistic resistance to a needle than alternative soft plastic and porcine gelatin materials.…”

“…Our work also relies on phantom data, but differs in that it focuses on the dynamic effects of needle insertion. Other related work includes the 2D prostate needle insertion simulation developed by Alterovitz, et al [9], and the Truth Cube developed by Kerdok, et al [10]. Our tissue phantom's design was inspired by the Truth Cube, a silicone gel volume with embedded fiducials whose displacements were tracked to estimate the gel's properties in compression tests.…”

Abstract. Models that predict the soft tissue deformation caused by needle insertion could improve the accuracy of procedures such as brachytherapy and needle biopsy. Prior work on needle insertion modeling has focused on static deformation; the experiments presented here show that dynamic effects such as relaxation are important. An experimental setup is described for recording and measuring the deformation that occurs with needle insertion into a soft tissue phantom. Analysis of the collected data demonstrates the time-and velocity-dependent nature of the deformation. Deformation during insertion is shown to be well represented using a velocity-dependent force function with a linear elastic finite element model. The model's accuracy is limited to the period during needle motion, indicating that a viscoelastic tissue model may be required to capture tissue relaxation after the needle stops.

“…In 2003 in a project named "Truth cube" 1 , Kerdok et al [3] validated their finite element deformation using the volumetric displacement data of 343 beads embedded in a silicone rubber cube and tracked by Computed Tomography. Material properties and geometry were known and boundary conditions had been carefully controlled while CT images were taken.…”

Abstract.Computer assisted procedures play a key role in the improvement of surgical operations. The current techniques in simulation potentially lead to more accuracy, more safety and more predictability in the surgical room. Despite the important number of algorithms proposed for interactively modelling deformable objects such as soft human tissues, very few methods have attempted to simulate complex anatomical configurations. In this paper, we present a new approach for soft tissue modelling whose novelty is to integrate the interactions between a given soft organ and its surrounding organs. The proposed discrete model is compared to finite element method in order to quantify its performance and physical realism. The model is applied to the simulation of the prostate-bladder set.

“…The manikin was designed to be deformable with constant volume. To achieve this, we selected medical-grade, two-part silicone rubber (model RTV6166, General Electric Company; Fairfield, Connecticut), which has proven successful for simulating tissue while maintaining constant volume [8]. This material is deformable but exhibits linear behavior to at least 30 percent strain with a stiffness of 780 N/m.…”

Abstract-Consensus is still lacking on how best to capture the shape of a residual limb. Computer-aided design systems have not proven more accurate, repeatable, or reliable than traditional plaster of paris methods. Research is limited in design, relates to clinical trials, and is based on opinions and clinical experience. Many outcome measurements are based on qualitative estimations of prosthetic fit or patient feedback rather than quantitative measurements. Research must identify the most accurate, repeatable, and reliable methods for residual-limb shape capture under conditions most likely to enhance socket fit. Measurement is difficult because a reference grid is required for identifying the residual limb's axis for ensuring direct comparison. This article describes a manikin production method for testing the shape capture of the residual limb. Diameters and volume were measured at specific levels with a programmable computer numerical control milling machine and a displacement tool, with a combined accuracy of 5 micrometers.
