Our expert spends time with the CT technician calibrating the machine for the optimum output. With this calibration set we can adjust each of the several hundred thousand data points to provide more accurate results.
Because CT scanners do not react well to metal, it is necessary to change the strings to nylon. However, the adjustment of the instrument is never breached. The instrument is removed from the case and the strings are replaced one at a time by our experienced luthier. Metal fittings such as the chinrest hardware and e-tuner are removed whenever possible for the best images.
The instrument is laid flat on its back in a soft, foam cradle and aligned with the laser guides. Our expert rolls the gantry (bed) into the scanner and hundreds of thousands of separate measurements begin to take place. In a matter of minutes, the scan is complete. The strings and fittings are replaced and the instrument goes back into its case. The process is completely non-invasive. The instrument is only out of its case for a few minutes and is not touched by any measurement tools.
The CT technician copies the aquired raw data onto our hard drive and we leave with the information in a format that cannot be read by anyone else to preserve anonymity. The information is used by us to create detailed thickness maps, elevation maps, density maps, and other images. The data is analyzed using software developed specifically for this purpose by our medical imaging specialist. All these images and information are crucial for our experts in preparing the detailed written report on the condition of the instrument.
The printed report is provided in a beautiful, hard-bound presentation book and contains a CD with the complete report and all generated images in a digital format. All of our work is strictly confidential based on the medical model of anonymity and nothing will be divulged without written permission of the person or entity that commissioned the report.
Confidentiality and transparency are extremely important to us; they are not mutually exclusive terms. The owner of an instrument has a right to confidentiality and controlled release of any information obtained and the potential buyer has the right to full disclosure. The core of our work is designing a system where both rights are respected and we believe we have been very successful at that.
