The laser scanning survey is one of the most updated and growing technique to acquire digital data for the architectural archives, including the cultural heritage applications and the archeological sites documentation. In the last years, many approaches have been proposed integrating digital photogrammetry and image processing algorithms. The laser scanner, sometimes, has been used only to prod...

PURPOSE To assess the three-dimensional repeatability of thickness measurements for epithelium, stroma, cornea, flap, and residual stromal bed using the Artemis very high-frequency (VHF) digital ultrasound arc-scanner (ArcScan Inc). METHODS Five consecutive measurements were obtained for 10 eyes of 10 patients 1 year after LASIK using the Artemis VHF digital ultrasound arc-scanner across the ...

Although new ultrasound signal processing can be designed from simulation data or recorded data, the development and prototyping of new medical ultrasound imaging tools is essentially based on processing the radio frequency (RF) data, which is the signal generated by the ultrasound probe. Unfortunately, the diversity and technological level of knowledge required for implementing a whole ultraso...

This technical procedure demonstrates a 4-step completely digital workflow for the fabrication of complete dentures in edentulous patients. The scan data arches were obtained using an intraoral scanner, followed by modeless trial denture bases additive manufacturing. Using base and wax rim assembly, interarch relationship was recorded. record digitized scanner reversed each maxillary mandibular...

Digitization is the process of converting information into a digital format. The economy that is based on digital computing technologies is known as Digital Economy. The digital economy is also sometimes called the Internet Economy or Web Economy. Right now, in most of the countries, inside the people’s wallet, they probably have a couple of credit cards, an identification card, automatic telle...

introduction: three-dimensional (3d) scanners are widely used in medicine. one of the applications of 3d scanners is the acquisition of anthropometric dimensions for ergonomics and the creation of an anthropometry data bank. the aim of this study was to evaluate the precision and accuracy of a modified 3d scanner fabricated in this study. methods: in this work, a 3d scan of the human body was o...

In China, efforts are being made to preserve historical documents in the form of digital data so that they can be effectively used while being protected. Stitching technology is expected to play a role in these efforts as it can be used to divide a large historical document into multiple areas, scan those areas using a compact contactless scanner, and seamlessly connect the resulting images. Si...

A desktop scanner was colorimetrically characterized to average CIELAB error of less than unity for Kodak Ektachrome transparencies and Ektacolor paper, and Fuji Photo Film Fujichrome transparencies and Fujicolor paper. Independent verification on spectrally similar materials yielded average ∆E*ab error of less than 2.1. The technique first modeled the image formation of each medium using eithe...

This study investigated the trueness of a digital implant impression according to orientation scan body (ISB) and scanning method. With flat surface ISB facing either buccal or proximal direction, was scanned using one tabletop scanner (T500) three types intraoral (TRIOS 3, CS3600, i500). The effects differences in method were assessed. Postalignment data subsequently obtained with abutments ge...

COVID-19 contact tracing is a preventive solution to slow the spread of virus. Several countries have implemented manual as well digital tracking using smartphone applications. A proximity-based system device BLE (Bluetooth Low Energy) technology focuses on and controlling virus in local communities. The devices consist signal sending (tag) receiving (scanner). Suppose factory. tag will be used...
