Aluminum Grid❤
Using a grid effectively removes unwanted stray lines and improves image contrast.❤

■ Features
- The JPI grid is manufactured using high-purity lead and is highly effective at eliminating scattered radiation.
- By using uniform aluminum and lead foils and polishing them with precision, we achieve high-quality, uniform images.
- You can eliminate moiré patterns by using a grid optimized for high density (such as 120 lines per centimeter) that matches the image sensor.
- We can provide simulation data based on physical properties that closely match actual measurements, as well as recommendations for optimal grid specifications.
- By developing and operating digital image analysis software in-house, we are able to provide a more stable and high-quality grid.
- In addition to 17×17-inch grids, we can also produce custom-sized grids, including medium and long-length sizes using MegaGrids.
- Using the carbon cover improves durability and ensures consistent X-ray transmission.
- In addition to standard square grids, we can also manufacture custom shapes to meet your specific requirements.
■ JPI Grid Specifications
| Size | Grid outer dimensions |
|---|---|
| Number per cm | Number of absorbent strands per 1 cm |
| Ratio | Grid thickness (ratio of absorbent material thickness to intermediate material thickness) |
| Focal length | Distance from the X-ray tube to the grid (FD/SID) |
■Megagrid
Traditionally, long and medium-sized grids were manufactured by joining two or three panels together. As
a result, the joints were located near the center of the image, which posed a problem because they interfered with the central area where the primary lesion was visible.
We have developed a technology that expands the maximum manufacturable grid size to 680 × 680 mm, and by positioning the joints at any desired location, we are able to produce grids that do not interfere with the center of the image.
