For the operator the process is similar to painting the ear canal and pinna with light. The scanner operates at 15 frames per second, with each section of scan data captured in 0.01 seconds - fast enough that any head movement or hand jitter is automatically captured and resolved by the scanner.Training Procedure
Users can be trained during a single training course. Performance is tested for proficiency on rubber ears, then human ears before training is completed.
Every scan is accurate, every time. The scanning system performs a self-validation before allowing the user to proceed with a scan.Accuracy
The scanner has a volumetric accuracy of +/-90μm. For perspective, both a human hair and a sheet of paper are about 100μm thick. That means if you laid a sheet of paper on a flat table, we could tell you the thickness of the paper. See our case studies enclosed.
The operator is presented with a real-time view of the collected scan data. During a scan, and before the customer leaves, the operator is automatically presented with scan completeness. The operator has the opportunity to review and add to the scan at any time if necessary.Scan Speed
A complete scan can be as quick as 90 seconds per ear.
United Sciences created three laser-scanning modes, which
enables the user to quickly capture every important surface of
the entire ear. Scanning the ear is as easy as A, B, C.
A: Industry Leading 3D Tracking – The eFit scanner’s tracking system was purpose-built for ear scanning, achieving unmatched accuracy, resolution, speed, working range, working angle, and mobility.
B: Ring Scanner – A live view of the ear canal is used to guide the user through a complete ear canal scan using a ring of blue light at the tip of the device probe.
C: Line Scanner – A line of laser light is projected from the scanner and is used to capture a majority of the outside of the ear, quickly and easily.
Safety – eFit allows the user to capture the true dimensions of the ear, eliminating silicone blowby risks.
Non-Contact – The scanning data is acquired with a non-contact laser scanning system.
Video Otoscope – The operator is presented with a real-time view of the ear and ear canal, which is used by the operator to obtain a safe and complete scan.
Depth gauge – The eFit scanware provides real-time estimated tip location and depth information to the operator, as well as a configurable depth target, warning message, and alarm.
