TWAIN with Eva Select Sensor Setup Guide

This guide describes the installation and setup of the ImageWorks Eva Select intraoral sensor for use with Dentrix Ascend Imaging via a TWAIN driver.

Overview

Dentrix Ascend Imaging supports the acquisition of intraoral images from ImageWorks Eva Select intraoral x-ray sensors via TWAIN drivers on a computer running the Windows operating system. The ImageWorks Eva Select sensor drivers must be installed on each computer that will acquire images from an ImageWorks Eva Select sensor.

Note: Prior to the installation of the ImageWorks Eva Select sensor drivers, the acquisition agent application must be installed on each computer that will acquire images. Refer to Setting up the acquisition agent for instructions on downloading and installing the acquisition agent.
