چکیده

In this paper we present our 3D simulation environment of the breast. The tool is based on Virtual Reality methods and can simulate in real time the dynamics and the deformations of a breast in 3D. Our breast models are defined using patient specific data reproducing the 3D geometry of the patient’s breast surface and approximating the physical properties of the internal breast tissue layers. 3D scans of the patient are used to define the geometry of the breast model and an experimental protocol is defined to acquire the physical properties of the model, as the tissue layers, their elasticity, mass and volume. The simulation environment permits a full 3D interaction with the breast model through graphic and haptic interfaces, 3D navigation, multiple display modes including textures, multiple lights and cameras. Resumo. Este artigo apresenta nosso simulador tridimensional do seio. A ferramenta é baseada em métodos de Realidade Virtual e pode simular, em tempo real, a dinâmica e as deformações de um seio em 3D. Nossos modelos do seio são definidos usando informações especı́ficas das pacientes, reproduzindo a geometria tridimensional da superfı́cie do seio da paciente e aproximando as propriedades fı́sicas dos tecidos internos do seio. Imagens tridimensionais da paciente são usadas para definir a geometria e um protocolo experimental é definido para adquirir as propriedades fı́sicas do modelo, como suas camadas de tecido, sua elesticidade, massa e volume. O ambiente de simulação permite uma interação tridimensional do usuário com o seio virtual, através de interfaces gráfica e háptica, navegação tridimensional, múltiplos modos de apresentação, incluindo texturas, luzes e câmeras.

Design of a Novel Recombinant Multi-Epitope Vaccine against Triple-Negative Breast Cancer

Background: Triple-negative breast cancer (TNBC) is determined by the absence of ERBB2, estrogen and progesterone receptors’ expression. Cancer vaccines, as the novel immunotherapy strategies, have emerged as promising tools   for treating the advanced stage of TNBC. The aim of this study was to evaluate Carcinoembryonic antigen (CEA), Metadherin (MTDH), and Mucin 1 (MUC-1) proteins as vaccine ...

Simulation of Store Separation using Low-cost CFD with Dynamic Meshing

The simulation of the store separation using the automatic coupling of dynamic equations with flow aerodynamics is addressed. The precision and cost (calculation time) were considered as comparators. The method used in the present research decreased the calculation cost while limiting the solution error within a specific and tolerable interval. The methods applied to model the aerodynamic force...

The influence of respiratory motion on dose distribution of 3D-CRT and IMRT- A simulation study

Background: 3DCRT (three-dimensional conformal radiotherapy) and IMRT (intensity-modulated radiotherapy) has provided us with tools to delineate the radiation dose distribution of tumor targets. However, the precision of radiation can be compromised by respiratory motion, which usually limits the geometric and dosimetric accuracy of radiotherapy. The purpose of this study is to evaluate the imp...

Optimization of tangential fields arrangement in the breast cancer 3D conformal radiation therapy

Introduction: The incidence of breast cancer increases with the rate of 1-2% at the world. Radiation therapy is one of the available choices for breast cancer treatment. The single isocentre half-beam block technique is considered as a standard technique to avoid hot and cold spots within the PTV. The major advantage of half beam technique is that the both contralateral breast...
