This 11×13 inch (28×33cm) X-ray anti-scatter grid fits 10×12 inch photosensitive media. Multiple grid ratios and focal distance options are available, with customizable grid density for radiography systems.
The 11×13 inch (28×33cm) X-ray anti-scatter grid is a high-performance radiographic accessory designed to match 10×12 inch photosensitive materials and flat panel detectors. It effectively filters scattered X-ray radiation generated inside the patient’s body, eliminates image haze, raises radiographic contrast, and delivers sharp, high-definition diagnostic images for clinical radiography.
The product supports flexible parameter customization to satisfy diverse imaging requirements. Standard grid density choices include 40 lines per cm (103 lines per inch), 52 lines per cm (132 lines per inch), and 60 lines per cm (152 lines per inch). Higher grid density reduces visible grid line artifacts on the final image, making it ideal for high-resolution digital DR systems. Users can pick the proper grid density according to detector resolution and clinical use cases.
A full range of grid ratios is available for selection: 8:1, 10:1, 12:1 and 14:1. The 8:1 grid ratio features wide exposure latitude and suits mobile radiography and imaging of thinner body parts. The 10:1 ratio is a versatile mainstream option for general radiography. Higher ratios of 12:1 and 14:1 provide stronger scatter suppression, perfect for thick anatomical regions where large amounts of scattered radiation are produced.
The focal distance (F.D) is optional from 0.8m to 2m. This wide focal range makes the focusing grid compatible with both fixed radiographic rooms and portable mobile X-ray equipment. It is critical to select the focal distance matching the actual working distance between the X-ray tube and grid. If mismatched, vignetting and brightness drop at the image edges will occur and affect diagnosis.
The core working principle uses alternating lead absorber strips and radiolucent interspaces. Primary X-ray photons travel along the gaps between lead strips and pass through the grid onto the detector. Random scattered photons strike the lead strips and get absorbed. Without an anti-scatter grid, scattered rays create a foggy overlay, blurring the boundaries between bone and soft tissue. This grid removes that fog and improves the distinguishability of subtle lesions.
Custom service is available for this 11×13 inch grid. Apart from standard specifications, the factory can adjust the overall dimension and technical parameters to meet special equipment integration needs. It works well in human radiography, veterinary DR imaging and research laboratory radiographic setups.
When deploying this X-ray grid, operators need to adjust exposure parameters accordingly. Higher grid ratios absorb more primary X-rays, so mAs compensation is required. The grid must be installed with the correct orientation, keeping the focal side facing the X-ray tube. With abundant configurable parameters and custom capability, this 11×13 inch anti-scatter X-ray grid is a reliable upgrade for radiographic imaging systems.
