RadiCS Chapter 9 Pattern TG18-LPH89, 50, 10 Supporting standard: EUREF TG-LPH89 TG-LPH50 TG-LPH10 Description Line pairs consisting of two single-pixel-wide horizontal lines with different grayscales are formed, covering the entire screen. The higher grayscale is equal to the lower grayscale +12%, and there are three types of patterns. The (high grayscale : low grayscale) values of the patterns are LPH89 = (255 : 228), LPH50 = (143 : 128), and LPH29 = (29 : 26).

RadiCS 81 Chapter 10 Information 2. About RadiCS Software 2-1. Prerequisite RadiCS Software We have long developed monitors. With those skills, knowledge and measuring data, we have developed RadiCS for users of medical image diagnosis to manage the quality of monitors efficiently according to our interpretation of the quality control standard for each medical image monitor.
RadiCS Chapter 10 Information Correlation Between DIN and RadiCS Pattern Check Screens without the aspect ratio 1:1 are not applicable since the aspect ratio of the test pattern in DIN is 1:1. Therefore, RadiCS has patterns with its own solution for each. Test Pattern 1 Test Pattern 2 Test Pattern 3 The same as Bild 3 pattern. Scaling must be in accordance with a screen resolution. The same as Bild 2 pattern. Scaling must be in accordance with a screen resolution. The same as Bild 5 pattern.

RadiCS Chapter 10 Information Correlation Between AAPM and RadiCS Pattern Check Screens without the aspect ratio 1:1 are not applicable since the aspect ratio of the test pattern in AAPM is 1:1. Therefore, RadiCS has patterns with its own solution for each one. TG18-QC TG-AD TG18-AFC TG18-CT TG-UN80 The same as each pattern. Scaling must be in accordance with a screen resolution. Grayscale 204 white patterns.
RadiCS 85 Chapter 10 Information Cautions AAPM constancy testing has 3 types, tests that monitor users perform daily, tests that medical physicists perform or QC (quality control) technologists perform under their instructions monthly / quarterly, and tests that medical physicists perform annually. RadiCS is mainly intended for constancy testing of the second type, but pattern checks can be performed for all three types of testing.
RadiCS Chapter 10 Information Grayscale Check ACR includes an equality sign but RadiCS doesn’t because the target error rate is < 10% of GSDF. This is a judgment condition for DICOM Part 14 GSDF. The number of grayscale measuring points is fixed at 18 and is unchangeable. The measurement result is 17 points because it is expressed as (JNDn + 1 – JNDn) / 2. Uniformity Check ACR includes only a notation about chromaticity uniformity of Δ(u’, v’).
RadiCS 87 Chapter 10 Information Correlation Between IEC, JIS and RadiCS Pattern Check Screens without the aspect ratio 1:1 are not applicable since the aspect ratio of the test pattern in IEC and JIS is 1:1. Therefore, RadiCS has patterns with its own solution for each. Test Pattern 1 Test Pattern 2 Test Pattern 3 Test Pattern 4 The same as Bild 2 pattern. Scaling must be in accordance with a screen resolution. The same as Bild 1 pattern. Scaling must be in accordance with a screen resolution.

RadiCS 89 Chapter 10 Information Luminance Check Lmax and Lmin specified in QS-RL include the ambient luminance and are the same as L’max and L’min used in RadiCS. QS-RL specifies Lmin Delta 1.0 cd/m2, but RadiCS includes no equality sign. Lamb stands for the ambient luminance and refers to the same value as “Ls” of DIN. The inequality Lmax/Ls > 100 (or 40) in the standard has been transformed into Ls > Lmax/100 (or 40). In QS-RL, the luminance is specified as |Delta Ls| ≤ 0.3 Ls.
RadiCS Chapter 10 Information Cautions Category A Mammo conforms to the PAS1054 mammography standard. This standard includes monitor resolution of 2000 × 2500 or above as a condition, but RadiCS makes no such determination.
RadiCS 91 Chapter 10 Information Correlation Between JESRA and RadiCS Pattern Check Since the test patterns used in JESRA have the aspect ratio of 1:1, they cannot be applied directly to monitors. Thus, RadiCS determines necessary test patterns based on the inspection to be performed and generates its own patterns corresponding to the monitor’s resolution. TG18-QC TG18-UN80 Clinical Image and JIRA CHEST-QC (JESRA) Equivalent to the pattern with the same name in the standard.
RadiCS Chapter 10 Information Uniformity Check Although JESRA includes an equality sign, each judgement condition in RadiCS does not. In the standard, the uniformity is checked with the TG18-UN80 patterns. However, since these patterns have the aspect ratio of 1:1, they are not applicable directly. RadiCS displays two windows (grayscale: 204) with the size of 10 % of the whole display area at the center and a corner of the screen. It then measures the luminance at the center of both windows.
RadiCS 93 Chapter 10 Information Uniformity Check IPEM recommends using TG18-QC or SMPTE patterns, but these patterns are not suitable for measuring 50% grayscale uniformity. Instead, RadiCS displays grayscale 128 windows equivalent to 10% of the display area in the center of the screen and in the corners, and measures the center portion of each window. IPEM includes an equality sign but RadiCS does not.
RadiCS Chapter 10 Information Correlation Between EUREF and RadiCS Pattern Check The patterns used for EUREF are the same as those used for AAPM. RadiCS determines the properties to be verified and independently prepares appropriate patterns for each resolution. TG18-QC TG18-LPH (89,50,10) TG18-LPV (89,50,10) This is scaled to match the resolution. This is scaled to match the resolution. This is scaled to match the resolution.

RadiCS determines the properties to be verified and independently prepares appropriate patterns for each resolution. TG18-QC This is scaled to match the resolution.
RadiCS Chapter 10 Information Luminance Check In DMG QCM, the luminance measurement does not include the ambient luminance. In RadiCS, an apostrophe (’) in the L’max, for example, indicates that it includes the ambient luminance. However, entering the ambient luminance value as 0 cd/m2 can effectively exclude the ambient luminance from the luminance measurement. Note that none of inequalities used in RadiCS includes an equality sign although every judgement condition in JESRA includes it.
