The TOR 18FG fluoroscopy phantom is a routine test object crafted for regular use, typically on a weekly or monthly basis. Its primary purpose is to facilitate a quick and easy assessment of imaging performance, focusing on aspects prone to deterioration. Following an initial grey-scale check, image quality is evaluated by counting the detected details and resolved bar-patterns. Maintaining a continuous record of these numbers allows for the detection of any trends indicating a decline in imaging performance over time. This approach ensures ongoing monitoring and enables timely intervention if needed to maintain optimal fluoroscopy imaging quality.

The TOR 18FG fluoroscopy phantom is a versatile tool used for fluoroscopy and fluorography, offering the capability to conduct various essential checks. These checks include:

1. Monitor Brightness and Contrast Adjustment:

• Assesses the adjustment of monitor brightness and contrast levels, specifically focusing on highlighting and lowlight details in the imaging.

2. Resolution Limit:

• Measures the resolution limit within a range of 0.5 to 5.0 line pairs per millimeter (LP/mm), providing insights into the system's spatial resolution capabilities.

3. Low-Contrast Large-Detail Detectability:

• Evaluates the system's ability to detect low-contrast large details, specifically using 18 details with an 8mm diameter. This test is crucial for assessing the system's sensitivity to subtle image variations.

4. Circular Geometry (Lead Circle):

• Checks the circular geometry, particularly the lead circle, ensuring that the imaging system maintains accurate and consistent geometric representations.

It's noteworthy that Frank Shields can provide smaller diameter field of view versions of the TOR 18FG fluoroscopy phantom upon request. These versions maintain the same features as the standard phantom, making them ideal for applications with mini C-arms.
