Section 7 – Technical Information
Kodak DryView Mammography Laser Imaging Film is a high-resolution,
infrared-sensitive, photothermographic film designed specifically for the DryView
8600 Laser Imager.
This new film delivers the same diagnostic image quality you get with your current
silver halide laser films – but it requires no “wet” chemistry, no “wet” film processors,
and no darkroom procedures. Which means there is no need for special plumbing,
wet chemistry disposal procedures, or modifications to your facility. This new film is
packaged in daylight load packages and is available in 8 inch by 10 inch size. It is
available in blue 7 mil polyester base.
Spectral Sensitivity
Kodak DryView Mammography Laser Imaging Film is infrared sensitive and has
been sensitized to the infrared laser diode of DryView Laser Imaging Systems.
When the film is handled according to instructions on the film package, safelights are
not needed. If you wish to remove undeveloped film from the daylight load package,
you will need a darkroom setting and a green safelight.
Image Quality
Kodak DryView Mammography Laser Imaging Film delivers diagnostic-quality,
continuous-tone images along with sharp alphanumerics and optimum contrast. This
high-quality silver-based film provides radiologists with diagnostic information similar
to that they are accustomed to viewing – including the spatial resolution, contrast,
and gray levels. Plus, because it is a totally dry imaging process, there is no image
quality variability due to “wet” chemistry.
Image Sharpness
Image sharpness is an important parameter for understanding image quality in
mammography. Image sharpness is determined by measuring the Sharpness
Transfer Function (STF) of square wave modulated bar patterns (on–off–on, etc.) of
various spatial frequencies.
The STF was calculated for the Kodak DryView 8600 Laser Imaging System using
the equation STF = (Dmax – Dmin)/(Dmax + Dmin), where Dmax is the maximum
density of the bars and Dmin is the minimum density between the bars. In order to
determine the STF, the DryView 8600 Laser Imager printed on–off–on bar patterns
on the film with various spatial frequencies at a maximum density of 3.5 OD.
