Barco's Mammo Tomosynthesis 5MP display system has been developed to optimize reading and
interpretation of digital breast images and breast tomosynthesis
The system uses DuraLight Nova backlights to ensure highly uniform images from center
to corner of the display
Additionally, DuraLight Nova provides twice the brightness of traditional mammography displays
Higher luminance boosts the apparent contrast of clinical images, which improves the visibility
of small details in breast tissues
This means that, even in bright image areas, which typically have poor contrast, the higher
luminance reveals conspicuous details
In dark image areas as well, details that were difficult to see before are now detectable
– because the smaller the object, the more luminance you need
Why?
First of all, the human eye has to contend with internal noise signals
Higher luminance makes images more discernible from the eye’s internal noise
Secondly, some of the light is not absorbed by the retina
This becomes worse as we grow older, making it more difficult to see small details
So, higher luminance is required to make up for this loss of light
Higher luminance also decreases the pupil’s diameter
And small details are more discernible with a small pupil opening instead of the other
way around
But how much brighter are Barco’s DuraLight Nova backlights?
One way to compare the brightness of medical displays is to count the Just Noticeable Differences
Traditional displays offer a calibrated luminance of 500 candela per square meter
DuraLight Nova offers twice the brightness of traditional mammography displays
And the I-Luminate button lets you boost the brightness up to 2000 candela per square meter
Plus, DuraLight Nova has twice the lifetime of traditional backlights – so the lifetime
of your backlights increases to no less than 5 to 7 years
In addition to high luminance, you also need high grayscale precision to avoid artifacts
Take a look at these gray rectangles
Although each gray rectangle is a uniform shade, the left side of each rectangle appears
darker than the right side
This effect – called banding – causes artifacts
To avoid banding, a 10-bit LCD panel is required, because it produces more gray levels – and
thus smoother grayscales – than an 8-bit panel
The higher luminance and smoother grayscales also allow you to read your studies in more
comfortable room lighting
So, no more dark reading rooms and no more eye fatigue
And because small details are more easily detected, you don’t need image manipulation
tools – such as the magnifying glass – as often to see them
DuraLight Nova also features film mode to illuminate reference film
In short, DuraLight Nova boosts detection and conspicuity of details, while doubling
your display’s lifetime and speeding your workflow
