DICOM files contain a lot of information stored in tags associated with the image.
The most important data is overlaid on top of the image displayed, grouped in the corners.
Depending on image modality, some fields may be missing.
•Number of displayed image and total number of loaded images
•Compression info (displayed only when lossy compression is used)
The following additional fields are presented only for MG modality (mammography):
•Patient first and last name
•Patient birth date and sex
•Rotation/flip (if applied)
•Mouse cursor position (coordinates of the pixel in displayed DICOM image) and value of the pixel
•Window level and window width (brightness and contrast), name of window preset, negative mode indicator
•Thickness and location of the slice (e.g. CT and MR modalities) or rotation and tilt of x-ray lamp (XA modality)
•Field strength (FS, only for MR modality)
•Repetition time, Echo time (TR, TE, only for MR modality)
•Date and time of image acquisition
If the DICOM image contains scale information (pixel spacing), two 10cm rulers with 1cm marks are displayed along left and bottom edges of the panel (red arrows).
If the DICOM image contains information about patient orientation in space, there is a letter (or combination of letters) symbolizing the patient’s sides displayed at the center of each panel's edge (green arrows).
•A – anterior
•P – posterior
•L – left
•R – right
