C PerfectLum PERFECTLUM USER MANUAL TABLE OF CONTENTS Introduction When it comes to medical imaging seeing the whole picture is important With a standard set up you run the risk of missing the details In turn this represents a health risk to the patient A missed detail may lead to an expensive PerfectLum lawsuit The problem isn t in the image itself or in the practitioners eye It is in the monitor itself PerfectLum adjusts your display to DICOM Digital Imaging Communications standards This changes your monitor from it s original calibration and ensures that you see the finer details of every image displayed With the software installed on all of your computers you thus ensure that no matter what image you are looking at it will be the same on every display This manual will walk you through all of the functions in PerfectLum To navigate the online manual use the buttons above to work through each section The links to the right will take you to other sections of the manual At any time you can return to this table of contents by clicking on the Main Window link also on the right TABLE OF CONTENTS Section 1 Installation Section 2 Setting Up PerfectLum Section 3 Measure Color Section 4 Perform Calibration Section 5 Scheduling Jobs Section 6 PerfectLum History Section 7 Checking Uniformity Section 8 Displaying Test Patterns Section 9 Dicom Conformance Section 10 Reference Calibration

In other words regardless of the capabilities of the Standardized Display System the same range of P Values will be presented similarly Image DICOM Presentation Values Standardized Modality of Polarity Presentation Display Interest System Note The Presentation LUT may be an identity function if for example the Polarity is unchanged and the Values of interest transformation outputs P values The Grayscale Standard Display Function is an element of the image presentation after several modifications to the image have been completed by other elements of the image acquisition and presentation chain The purpose of defining this Grayscale Standard Display Function is to allow applications to know a priori how P Values are transformed to viewed Luminance values by a Standardized Display System In essence defining the Grayscale Standard Display Function fixes the units for the P Values output from the Presentation LUT and used as Digital Driving Levels to Standardized Display Systems A second objective to select a Display Function which provides some level of similarity in grayscale perception or basic appearance for a given image between Display Systems of different Luminance and which facilitates good use of the available Digital Driving Levels of a Display System While many different functions could serve the primary objective this Grayscale Standard Display Function was chosen to meet the second objective With such a fun

4. The human eye is relatively less sensitive in the dark areas of an image than it is in the bright areas of an image This variation in sensitivity makes it much easier to see small relative changes in Luminance in the bright areas of the image than in the dark areas of the image A Display Function that adjusts the brightness such that equal changes in P Values will result in the same level of perceptibility at all driving levels is perceptually linearized The Grayscale Standard Display Function incorporates the notion of perceptual linearization without making it an explicit objective The employed data for Contrast Sensitivity are derived from Barten s model of the human visual system Specifically the Grayscale Standard Display Function refers to Contrast Sensitivity for the Standard Target consisting of a 2 deg x 2 deg square filled with a horizontal or vertical grating with sinusoidal modulation of 4 cycles per degree The square is placed in a uniform background of Luminance equal to the mean Luminance L of the Target The Contrast Sensitivity is defined by the Threshold Modulation at which the grating becomes just visible to the average human observer The Luminance modulation represents the Just Noticeable Difference ND for the Target at the Luminance L Note The academic nature of the Standard Target is recognized With the simple target the essential objectives appear to be realizable Only spurious results with more realistic tar

It does not define when conformance with the Grayscale Standard Display Function is achieved or how to characterize the degree of conformance reached Note A definition of conformance would require thorough evaluations of human visual system sensitivity to deviations of Display Functions from the Grayscale Standard Display Function for medical images Figure show the context for the Grayscale Standard Display Function The Grayscale Standard Display Function is part of the image presentation There will be a number of other modifications to the image before the Grayscale Standard Display Function is applied The image acquisition device will adjust the image as it is formed Other elements may perform a window and level to select a part of the dynamic range of the image to be presented Yet other elements can adjust the selected dynamic range in preparation for display The Presentation LUT outputs P Values presentation values These P Values become the Digital Driving Levels for Standardized Display Systems The Grayscale Standard Display Function maps P Values to the log luminance output of the Standardized Display System How a Standardized Display System performs this mapping is implementation dependent The boundary between the DICOM model of the image acquisition and presentation chain and the Standardized Display System expressed in P Values is intended to be both device independent and conceptually if not actually perceptually linear
