It is widely acknowledged that image thinking is significant in medical education. The colorful pictures and animations need to be presented for the users (observers) to make the content easier to be understood. By the appropriate matching of pictures and text, readers are able to associate the text with the image on the screen to reach better understanding. In this case, 3d and dynamic images will take the place of the plane and static ones. The study software applied the image processing software and animation software, such as Photoshop, Flash software. 3d max software is used for processing and preparation the simulation stereo skeleton. the Java language of Cult 3D models help give the characteristics of model rotating and zooming in and out; Using multimedia interactive software, Neobook, makes sure interactive amity of interface and establishes a good interactive operating environment between the users and 3d models. For the basic medical education which has higher visual thinking demand, multimedia education has already be widespreaded and used. This software has interactive function and three-dimensional content, 3d instead of static, dynamic replace static state. It is not only keeping the traditional advantage (such as the logical arrangement of content, strictly text description, etc.), but also providing the learning reference material to the users which has intuitive visual experience, independently and freely self-selection, flexible processing. It is beneficial to understand and learn related contents. This study software shows rich and colorful pictures, 3d dynamic display contents, animation process of image to the users, so as to increase understanding and grasping the contents on human spine. It has multiple functions such as help studying and teaching.

The implementation of numerical methods to solve and study equations for cardiac wave propagation in realistic geometries is very costly, in terms of computational resources. The aim of this work is to show the improvement that can be obtained with Chebyshev polynomials-based methods over the classical finite difference schemes to obtain numerical solutions of cardiac models. To this end, we present a Chebyshev multidomain (CMD) Pseudospectral method to solve a simple two variable cardiac models on three-dimensional anisotropic media and we show the usefulness of the method over the traditional finite differences scheme widely used in the literature.

Three dimensional (3D) printed cardiac models are useful for WATCHMAN device procedural planning, sizing, and complication reduction. These models also provide accurate representation of dynamic heart anatomy, helping practitioners determine their procedural approach and select proper device sizing. While the efficacy of 3D models obtained from Computed Tomography and Transesophageal Echocardiography over 2D Transesophageal Echocardiography imaging for WATCHMAN procedural planning has been demonstrated, this project aims to directly compare 3D Computed Tomography versus 3D Transesophageal Echocardiography and determine which is more favorable. Computed Tomography and Transesophageal Echocardiography 2D imaging studies from patients that underwent LAA WATCHMAN closure device implantation we used as templates for 3D cardiac models. These 3D models were scored using a 10-point Likert questionnaire. Scoring was conducted by a diverse team that included cardiologists, research specialists, medical students, and 3D printing technicians.  Three dimensional models developed using Computed Tomography demonstrated favorability over 3D models by all qualitative measures. Scoring indicates that Computed Tomography based 3D models are superior tools for WATCHMAN sizing, multi-level medical education, and physician preparedness. To our knowledge, this is the only study that compares 3D models crafted from each imaging modality, and we hope that it encourages future use of 3D modeling techniques based on Computed Tomography scans.
