The PTI-890 Quad Gamma Test Pattern Phantom consists of four frequencies of parallel-line equally spaced bars arranged in an L-Shaped configuration in each of its quadrants. This type of bar configuration allows the user to measure spatial resolution and spatial linearity in all four quadrants of a gamma camera with one image.
There is no need to turn the phantom and take multiple images to ensure that each camera quadrant is tested with each bar width.
