Area of Science:

Medical Imaging
Digital Image Processing

Background:

Flatbed scanners offer a potential method for digitizing radiographs.
Assessing the performance of these scanners is crucial for reliable medical image acquisition.

Purpose of the Study:

To evaluate the physical performance of a flatbed scanner for digitizing radiographs.
Key performance metrics investigated include dynamic range, reproducibility, and homogeneity.

Main Methods:

An Artix ArtiScan flatbed scanner and Aldus PhotoStyler software were used.
A stepped exposure Kodak T-MAT G film was scanned under various conditions.
Scanned images were analyzed for pixel value distribution and compared to laser densitometer measurements.

Main Results:

Default settings yielded a narrower pixel value range than the film's optical density.
Increasing scanning time widened the pixel range but did not fully match optical density profiles.
Characteristic curve was steeper than the film's; results varied with scan position and time.
Reproducibility was achieved under consistent scanning conditions and after scanner warm-up.

Conclusions:

Flatbed scanners require careful calibration for reliable radiograph digitization.
Operating conditions significantly influence scanner performance and data accuracy.
