Adding image files

Top  Previous  Next

DICOM Search can read DICOM image files stored on your computer or on a network share, and store the DICOM tag values in a tags database.  You can add image data to a library when creating a new library, or editing an existing library.  Click on the Add / update images from folders button to start processing your images.





Enter the details of the files to read.





Enter the file search patterns to locate the images you want to process.  The search pattern is identical to that used by Windows to locate files.  For e.g. if we wanted to process only files starting with the word Toshiba, we would enter the following:




If we wanted to process only files with the dcm extension, we would enter the following:





To also process files located in the subfolders of the folders we entered, select the Search recursively option.





For each processed file, we can choose to create thumbnails of the image.  Select the Create thumbnail images option, and specify the maximum height and width of the thumbnail (in pixels).  DICOM Search will maintain the aspect ratio of the image in the thumbnail.





Creating thumbnails of your DICOM images will allow you to quickly see what your images contain without having to open the actual image.  You can view the thumbnails in your result sets by including the ds_thumbnail column in your SQL query.


The Additional key value is a value you can use to uniquely identify the set of images that are being processed in this batch.  For example, you may decide that images processed from organization A will use the key value HR_100_20201101, images from organization B will use the key value HR_200_20201101, etc.  When you then search the tags database, you can use this key value to further refine your search.  This value is stored in the ds_customkey column.





The Thread count option sets up DICOM Search to index your files in parallel to speed up the indexing process.  The default value is 1 less than the number of logical processors on your machine, and 2 for machines with 2 logical processors.





Finally, if this is the first set of images you are processing for the selected library, you can specify the location of the tags database file.  If you will be indexing a lot of images, it is best to store the tags database file on a hard disk with a lot of spar
