MicroCT Service Request Guide

High-resolution micro-computed tomography (microCT) is a powerful non-destructive imaging technique used to visualize the internal structure of samples in three dimensions. To ensure high-quality data acquisition and efficient processing, laboratories follow a standardized service request workflow. This guide outlines the typical steps involved in submitting a sample for microCT analysis.

1. Preliminary Consultation

Before submitting a formal request, researchers should engage with the facility staff. During this phase, you will discuss the research objectives, the nature of the samples, and the required resolution. Staff can advise on feasibility, potential artifacts, and sample preparation requirements to ensure the imaging parameters align with your research goals.

2. Sample Preparation and Safety

Proper sample preparation is critical for successful microCT scans. Depending on the material, samples must be stabilized to prevent movement during the rotation process. Key considerations include:

• Size Constraints: Ensure the sample fits within the field of view of the scanner.
• Density: High-density materials may require specific filter settings to avoid beam hardening artifacts.
• Hazardous Materials: All samples must be clearly labeled and declared. Biological or chemical hazards require specific safety documentation prior to submission.

3. Formal Submission

Once the project parameters are finalized, a formal request form must be submitted. This document generally requires:

• Contact information and project funding details.
• Detailed sample description (material type, size, and quantity).
• Specific scanning requirements (desired voxel size, rotation steps, and field of view).
• Requested turnaround time and data delivery format.

4. Data Acquisition

After the sample is accepted, the facility team will perform the scans. This stage involves setting up the X-ray source and detector geometry to optimize contrast and resolution. Once the raw projection data is collected, a reconstruction algorithm is applied to convert these projections into a 3D volume (typically in DICOM or TIFF formats).

5. Data Analysis and Transfer

Following successful reconstruction, the data undergoes a quality control check. Once approved, the facility will provide instructions for downloading the reconstructed volumes. Many facilities also offer post-processing services, such as 3D segmentation, porosity analysis, or morphometric measurements, which can be arranged as part of the service request.

Best Practices for Success

To avoid delays, ensure that all samples are properly packaged and clearly labeled with unique identifiers. If your research involves time-sensitive experiments, coordinate with the facility well in advance to reserve equipment time. Clear communication regarding your specific analytical needs will ensure that the resulting data provides the insights necessary for your research project.
