Combining Surgical Navigation and 3D Printing for Less Invasive Pelvic Tumor Resections

Pelvic Resections: Surgical Considerations and Classification

Pelvic resections.

The complexity of pelvic anatomy and the extent of tumor growth makes treatment of patients with primary bone sarcomas in the pelvis difficult in terms of local control. Before the 1970s, most tumors in the bony pelvis were surgically treated with hindquarter amputation. Currently, improved techniques for clinical staging, adjuvant treatments, evolutions in metallurgy, and development of new su...

Surgical Planning by 3D Printing for Primary Cardiac Schwannoma Resection

We report herein a case of benign cardiac schwannoma in the interatrial septum. A 42-year-old woman was transferred from a clinic because of cardiomegaly as determined by chest X-ray. A transthoracic echocardiography and chest computed tomography examination revealed a huge mass in the pericardium compressing the right atrium, superior vena cava (SVC), left atrium, and superior pulmonary vein. ...

Fabrication of Capacitive Acoustic Resonators Combining 3D Printing and 2D Inkjet Printing Techniques

A capacitive acoustic resonator developed by combining three-dimensional (3D) printing and two-dimensional (2D) printed electronics technique is described. During this work, a patterned bottom structure with rigid backplate and cavity is fabricated directly by a 3D printing method, and then a direct write inkjet printing technique has been employed to print a silver conductive layer. A novel ap...

designing and implementing a 3D indoor navigation web application

​During the recent years, the need arises for indoor navigation systems for guidance of a client in natural hazards and fire, due to the fact that human settlements have been complicating. This research paper aims to design and implement a visual indoor navigation web application. The designed system processes CityGML data model automatically and then, extracts semantic, topologic and geometric...
