Example 1: Defining a Dataset with DICOM Data

Explains how to define a dataset with DICOM Data.

The Data Schema

The Data Schema can be uploaded as a CSV to the Rhino Web UI or added directly to the Rhino Web UI through the built-in Data Schema editor. For this example, we will create this Dataset within the UI and name it Stroke Schema.

Field Name	StudyInstanceUID	SpO2	Stroke Present	Number of Points	Gender
Identifier				(5000, 0010)
Description
Type	DicomStudyUID	Percent	Boolean	DicomTag	Enum
Type Parameters					{"choices": ["m", "f", "o"]}
Sensitive Data	No	No	No	No	No
Aggregate Statistics	Allowed (Enabled)	Allowed (Enabled)	Allowed (Enabled)	Allowed (Enabled)	Allowed (Enabled)
Secure Access	Allowed (Enabled)	Allowed (Enabled)	Allowed (Enabled)	Allowed (Enabled)	Allowed (Enabled)

The Dataset's Tabular Data

The tabular data CSV file is prepared within the institutional firewall from data in clinical systems and then copied via SFTP to the Rhino Client.

StudyInstanceUID	Gender	SpO2	Stroke Present?
1.3.12.2.1107.5.4.3.11540117440512.19970422.140030.45	m	0.97	True
1.3.12.2.1107.5.4.3.123456789012345.19950922.121803.6	m	0.98	False
1.3.12.2.1107.5.4.3.4975316777216.19951114.94101.16	f	0.95	True
...	...	...	...

For this example: Let’s say this tabular CSV file was copied via SFTP to the following location on your Rhino Client: /rhino_data/uploads/stroke/dataset1.csv

The Dataset's DICOM Data

All DICOM files associated with the studies in the tabular data file are queried from the PACS, de-identified, and then copied via SFTP to the Rhino Client.

The Rhino Client doesn’t require or expect any specific file structure, so all .dcm files can be put under the same directory, under sub-directories (e.g., for each study or series), or a mix of the two.

For this example, let's say we place our DICOM data in the following locations on our Rhino Client:

• /rhino_data/uploads/dicom_data/

1.3.12.2.1107.5.4.3.11540117440512.19970422.140030.46.dcm

• /rhino_data/uploads/dicom_data/another.dcm

• /rhino_data/uploads/dicom_data/1.dcm

• /rhino_data/uploads/dicom_data/study1/1.dcm

• /rhino_data/uploads/dicom_data/study1/2.dcm

• /rhino_data/uploads/dicom_data/study2/1.dcm

The Dataset's File Data

No file data exists in this Dataset

Importing the Dataset into the FCP

1. Name: Example 1 Dataset

2. Description: Example 1 Dataset

3. Data Schema : Stroke Schema v0

4. Tabular Data File Path : /rhino_data/uploads/stroke/dataset1.csv

5. DICOM Data Path :

   • Import Method: Filesystem

   • Path: /rhino_data/uploads/dicom_data

6. File Data Path : /rhino_data/ (Default Value: Do not change)

7. Is Data De-identified?: Yes
