# InstancesIdReconstructPostRequest
## Properties
**limit_to_this_level_main_dicom_tags** | Option<**bool**> | Only reconstruct this level MainDicomTags by re-reading them from a random child instance of the resource. This option is much faster than a full reconstruct and is useful e.g. if you have modified the 'ExtraMainDicomTags' at the Study level to optimize the speed of some C-Find. 'false' by default. (New in Orthanc 1.12.4) | [optional]
**reconstruct_files** | Option<**bool**> | Also reconstruct the files of the resources (e.g: apply IngestTranscoding, StorageCompression). 'false' by default. (New in Orthanc 1.11.0) | [optional]
