This study aims at obtaining a patient specific 3D model of human knee joint from Computed tomography (CT) data via reverse engineering approach. CT scan data in digital imaging and communications in medicine (DICOM) format was loaded into DeVide, medical image processing software to obtain 3D Computer aided design (CAD) model. The CAD model was saved in Stereolithography (STL) format, which was further processed in MeshLab and MagicsRP software to obtain error-free file. Static stress and deformation analysis at the joint was performed for Stainless steel (SS 316L) and CoCrMo alloy in ANSYS software. Anatomical model of the knee joint was fabricated on EOSINT P395 machine using PA2200 polyamide powder. Finite element analysis shows that CoCrMo alloy has lower deformation in comparison with stainless steel. (C) 2018 Elsevier Ltd. All rights reserved.

The medical device industry is experiencing a move toward devices that communicate with cell phones, primarily driven by the desire for lower-cost medical monitoring tools that promote personalized medicine. A concurrent phenomenon is the emergence of makerspace resources that allow individuals, as hobbyists or engineers in training, to prototype technical gadgets with the aid of 3D printers and connectible components - components that would traditionally have been designed from the ground up by a trained engineer but can now be purchased with standardized interfaces and supporting software libraries. This paper describes the initial implementation of a wearable electrocardiograph project for a senior-level undergraduate biomedical instrumentation course sequence at Kansas State University. The project integrated circuit-level design concepts with makerspace tools consistent with the move toward personalized medicine. Each student in the course was tasked with designing a wearable electrocardiograph that communicates with a cell phone via a Bluetooth Low Energy (BLE) link. The student was responsible for the low-level analog circuit design (e.g., differential amplifiers, filters, and single-ended design for battery operation), the digital circuitry (e.g., analog-to-digital conversion), the board layout/population, and the 3D-printed case. Due to time constraints, teaching-assistant help was offered in terms of the BLE data transmission and the cell phone app. Portable data acquisition hardware (Digilent Analog Discovery 2 units) and virtual instrument software (WaveForms 2015 software) provided students with means to build and test circuitry outside of the confines of traditional benchtop laboratories. Student performance was assessed relative to learning objectives specified for the project, and pre/post surveys were employed to gauge student self-perceptions of learning with regard to physical device components, instrumentation concepts, analog circuitry, digital

In this paper, the restoration of the Mandible after trauma or eradicated as a result of cancer tumors is a difficult challenge faced by Oral and maxillofacial surgery. The mandible is an essential element in the appearance of the human face. It gives the distinctive shape of the face, carries the lower teeth, and also supports the processes of expression, breathing and chewing. The purpose of this paper is to propose a new methodology and strategy that provides an integrated environment of techniques and software used to simulate implantation based on patient medical imaging data and the creation of an STL model. The implantation included a case study of a 35-year-old man with a traffic accident in the Mandible. Obtained patient data obtained from CBCT to design a medical model for the required area. modeling done using threshold technology and computer-aided design. A suitable environment for a comprehensive medical simulation was developed to construct the final medical model and integrate implantation and mandible using the Meshmixer platform. The proposed processes and methodology illustrate the possibility of more specialized implantation where rapid prototyping and reverse engineering techniques can be applied in the medical field to improve surgery, diagnosis, and treatment.

With the development of computer technology, computer technology has been used to simulate human factors in the field of maintenance, that is, the application of human body data in maintenance engineering through advanced technology methods, so as to obtain the maintenance design principles and basis. Virtual Reality(VR) provides a new idea for ergonomics applied to equipment maintenance, that is, to build a virtual maintenance environment, introduce a digitalhuman-machine model, and simulate the maintenance process to achieve the maintenance process. Simulation and corresponding ergonomics analysis provide a powerful aid for maintenance design and maintenance process analysis.

The aim of this exploration is to research on the simulation of virtual wetsuit wearing effect with 3D software technology based on 2D pattern block. We make wetsuits try-on test of different sizes according to the female human body models we built, then check the pattern design and the clothing comfort in accordance with the "human body-wetsuit" system, and finally modify and adjust the pattern constantly to achieve our desired goal. It will help designers to omit the repeated actual manufacture modifying works for the optimized pattern block design of wetsuit.
