Typical workflows for microtomography experiments at I12, I13-2 and DIAD will be presented. I12 (53-150keV) and I13-2 (8-30keV) are suited to large and small samples respectively, and the new beamline DIAD (7-38keV) will allow simultaneous imaging and diffraction for small samples. Methods for accurate beamline alignment and stable sample mounting will be discussed, together with the...
At SOLEIL's tomography beamlines, tomography acquisitions are performed using the SOLEIL FlyScan continuous scanning architecture. The resulting data are reconstructed using PyHST2. In both cases, a layer of Python code has been developed to guide the user through the process, aligning samples, setting parameters, correcting artefacts, and launching reconstructions. Batch or pipeline...
Recent trends in hard X-ray biomedical microCT aim at pushing the limits in both spatial and temporal resolutions. Additionally, when functional parameters in small animal organs need to be accessed, microCT has to be performed in vivo. All these challenges necessitate intense and coherent photon beams. To address these requests, the ESRF-ID17 biomedical beamline is equipped with different...
The ESRF tomography acquisition and processing software has traditionally suffered from fragmentation across the different beamlines, resulting in many different solutions for similar problems.
The associated maintenance and development costs have severely hindered its progress.
We are currently re-thinking our acquisition and processing workflows from scratch, with a unified underlying...
After a general presentation of the beamline, specifically the workflow for ex-situ CT at BAMline is presented. Although being used in a broad variety of research fields the usual workflow for CT experiments is in most cases similar in terms of sample mounting, tomographic scan and reconstruction. Specific scanning schemes allow for a preview reconstruction carried out during the scan. A...
Most users at the Nanotomography endstation at P05 are not very experienced in synchrotron tomography measurements, as they are coming from very different fields, e.g. Biologist, Geologist or Medics. The setup of a transmission x-ray microscope (TXM) however is often more complex with respect to sample alignment, different detector choices and varying scan parameters. An in-house developed...
I will demonstrate the process of setting up scans, collecting data, and doing image processing at Beamline 8.3.2 (microCT) at the Advanced Light Source (ALS) at Lawrence Berkeley National Laboratory. Like many of the beamlines at the Advanced Light Source (ALS), Beamline 8.3.2 uses Labview for beamline and enstation control, which provides convenient graphical interfaces for doing many tasks,...
In this workshop, we will first give a short presentation (~20 min) on how full field tomography is performed in a standard way at TOMCAT. The latest developments achieved to ease the operation will be presented: hdf5 data handling, reconstruction pipeline optimisation, offline HPC cluster and data management.
In a second part, a live interactive demo and discussion round (~40 min) will be...
