all kinds can be imaged. The sample size can be up to 100 mm in diameter, with the resulting image resolution being proportional to the sample size. Typical scan time per sample is 2 hours, but depends on the required image quality and sample size. The scan time is usually in the range of 10 minutes to 240 minutes.

  • Quantitative Analysis of Synthetic Materials:

    Synthetic materials can be fabricated for any purposes in every fields. For example scaffolds with properties similar to trabecular bone are samples of synthesized materials for biological purposes.

    LOTUS Micro-CT systems can be used to quantify parameters like porosity of scaffolds or mineralized matrix formations by high resolution 3D imaging and applying different image processing algorithms.

    LOTUS Micro-CT chain starts with acquisition of very precise projections, continues with 3D fast and robust reconstruction, 2D and 3D visualization, processing and measurements and ends with enabling users/operators to analyze their samples with a friendly user interface (UI).

    Thus, the internal structure and micropores of any biological or non-biological materials like scaffolds seeded with rat calvarial (Cal) or marrow stromal (Str) cells can be analyzed, both quantitatively and qualitatively( i.e. visually), by utilizing LOTUS X-ray microtomography scanners.

    Micro-CT imaging should be a non-separable activity for quality control and quantitative assessment of any synthesized materials, especially biological implants or scaffold which are embedded in human bodies.

    In addition to LOTUS scanners sales, LOTUS Micro-CT lab provides 3D imaging and analysis services worldwide with very low prices with providing results very fast.

  • Bone Mineral Density Analysis:

    Bone mineral density (BMD, mg/cm3) is an important measure in the evaluation of osteoporosis. LOTUS-inVivo and LOTUS-inVitro Micro-CT systems provide a non-destructive way of measuring bone mineral density in Pre-clinical studies.

  • Digital Rock Analysis:

    Micro-CT scanners are able to perform X-ray imaging of core sub-samples from 10 to 500 times higher resolution than macro-CT scanners, known as medical CT scanners. Scan resolution is generally guided by the size of the sample, so the smaller the sample, the higher the resolution.

    A 25-micrometer resolution sub-sample scan (a standard test plug) is being used in the sample selection process for sophisticated reservoir-condition flow studies.

    Small features (e.g., micro fractures, small vugs, anomalies, etc.) are hard to visualize with macro-CT imaging but are captured well with micro-CT scanners. Primarily, these scans are used as an advanced screening tool for high-value testing. However, scan data bring extraordinary value for quantifying varying phases in plug samples (e.g., salt crystal locations, location of asphaltene, distribution of fluids, etc.) for assessment of their impacts on porosity, permeability and flow behavior. Fracture propagation as a result of increasing vertical stress on rocks also can be visualized.

    LOTUS-NDT Micro-CT scans at higher pore-scale resolutions help resolve features as small as 1 micrometer. Image acquisition and segmentation at such resolutions aid in grain and pore system characterization. When consolidated with appropriate and extensive physical measurements, petrophysical data such as permeability, capillary pressure and electrical properties are quantified. Confidence in modeling petrophysical data is improved using models calibrated to laboratory measurements. Imaging and quantification of these properties also are ideal for friable to unconsolidated samples and large-sized drill cuttings or when core recovery is poor. The rock-based digital physically constrained models provide data that correlate well to conventional core analyses.
