microCT

AttributeValues
ModalitymicroCT
InstrumentBruker Skyscan 1276
Output file structureOne folder with one or more subfolders based on user preferences. (some users put all their data from multiple scans in one giant folder), Between 200 and 3600 tif files (raw data, per FOV scanned, so maybe 3-10x this many in some cases), Between 1 and 10000+ image files (reconstructed data, can be tif, bmp, jpg, png, dcm), 1 or 2 log files (one for acquisition, one for reconstruction (optional), .log plain text), 1 bitmap image, 1-N .oog files (log files for subscans when multiple (N) FOV are imaged), 1-100 tif files (leftovers from reconstruction process, names like “mouse_~02_ar3.tif”), Not all users will do reconstruction on the acquisition computer, so those files may not be present., If InstantRecon is used, possibly hundreds of .iif temp files it fails to delete when done), 1-N csv file with x-ray dose information, 0-N .txt files including a suffix like ‘PreviewInfo.txt’, up to one per N FOVs imaged
Naming conventionAll names are up to the user.\xa0 Reconstructed files include “rec_00” in the middle. Raw data includes an 8-digit number starting with 00000000.

Jan 1st 2023 12:35:35 would be 20230101123535___, Study name can be changed and will be viewable in lab share and w/in analysis and acquisition software, Default series and image name as shown in lab share: 4-digit year, 2-digit month, 2-digit day, 24-hour time, seconds, (3 digits)., Default series name in analysis and acquisition software is a sequentially numbered starting at 1 “Series X”. If series name is edited from default, it will be viewable w/in analysis software. If no image name is given during acquisition, it will be blank w/in analysis and acquisition software. If image is given name during acquisition, it will be viewable w/in analysis and acquisition software.
