Observation Picture - mbarnig/RadioLogic GitHub Wiki

The following figure shows a typical example how to provide the clinical data of a patient with free text in a grayscale picture.

The 64x64 pixels sized thumbnail in the left top corner is used to present the clinical case in the list displayed in the fourth tab of the RadioLogicTutor viewer. The Observation picture can be monochrome, grayscaled or colored. For best results it should be in PNG format with a size of 960x640 pixels.

The Observation picture is embedded into a DICOM instance. The text strings containing the possible diagnoses of the multiple choice questionnaire are inserted as private tags into this DICOM file. Another private tag shows the author of the clinical RadioLogic case.

To prevent the user to commit fraud in the test by exploring the DICOM metadata, the correct diagnosis is saved in scrambled form. The realted scramle key is also added as private DICOM tag in the Observation DICOM instance

The next chapter describes the Answer Picture.
