The 2214 features a nanofocus X-ray source and multiple detectors, providing the broadest range of applications for high-resolution imaging.

What is the difference between the two X-ray sources available in the X4 Poseidon Modular Micro-CT?

The X4 Poseidon Modular Micro-CT offers two X-ray sources, each with distinct imaging capabilities. One is a transmission source with a spot size as fine as 2 μm, providing higher resolution. The other is a reflection source with a spot size of 5 μm.

The key difference is in the 3D spatial resolution:

• Transmission source: Voxel size of 2 x 2 x 2 μm (8 μm³)
• Reflection source: Voxel size of 5 x 5 x 5 μm (125 μm³)

This results in a 15.6x improvement in resolution with the transmission source, allowing for significantly finer detail in your scans compared to previous Bruker desktop micro-CT systems. If you don’t require such high resolution, the reflection source could be a more affordable alternative while still providing excellent imaging performance for less detailed scans.

What is the smallest spot size on the Poseidon?

The transmission X-ray source on the X4 Poseidon Modular Micro-CT offers the smallest spot size in Bruker’s desktop micro-CT lineup, with a resolution of 2 μm. This is 15.6x finer than the spot sizes available on previous generations of desktop micro-CT systems, providing exceptional detail in imaging.

What is the difference between X-ray spot size and pixel size in a Micro-CT system?

In a micro-CT system, the spot size refers to the smallest area the X-ray source can focus on and defines the ultimate edge of resolution for the system. It’s the smallest possible feature that the X-ray system can resolve.

On the other hand, pixel size refers to the 2D size of each pixel projected onto the detector. The pixel size is an important factor in determining the resolution of the final scan. If the pixel size is much larger than the spot size, it becomes the limiting factor for resolution. To achieve the highest resolution, the pixel size should be several orders of magnitude smaller than the X-ray spot size, allowing multiple pixels to be used to resolve smaller features.

If I have used a SkyScan Micro-CT in the past, do I need specific training for the X4 Poseidon Modular Micro-CT?

While the SkyScan series of micro-CT systems and the X4 Poseidon share similar technology, the methods for optimizing and setting up scans differ.
