This practice describes the format, dimensions, and contrast required to make diagnostically significant measurements of the display and camera system resolution for both digital and analog monochrome signal sources. The practice provides users of medical diagnostic imaging systems with a comprehensive test pattern for day-to-day operational checks and adjustments of focus, brightness and contrast, resolution response, mid-band streaking, uniformity, and linearity of viewing monitors and hard copy recordings. This practice is not intended to create a standard for image characteristics such as resolution, geometry and linearity, uniformity, phosphor defects, etc. However, use of the pattern is encouraged as an appropriate tool for evaluating the measurement and specification of such image characteristics.
