Constructing a Query

Using search in Atlas requires a structured query.

Familiarize yourself with the structure of the data stored in Atlas.

Gradient Health, Inc stores data for all DICOM tags. This is our general schema: 

[
  {
    "name": "Modality",
    "mode": "NULLABLE",
    "type": "STRING",
    "description": null,
    "fields": []
  },
  {
    "name": "Body_Part_Examined",
    "mode": "NULLABLE",
    "type": "STRING",
    "description": null,
    "fields": []
  },
  {
    "name": "Slice_Thinkness",
    "mode": "NULLABLE",
    "type": "FLOAT",
    "description": null,
    "fields": []
  },
  {
    "name": "Patient_Sex",
    "mode": "NULLABLE",
    "type": "STRING",
    "description": null,
    "fields": []
  },
  {
    "name": "source_uri",
    "mode": "NULLABLE",
    "type": "STRING",
    "description": null,
    "fields": []
  },
  {
    "name": "patient_id",
    "mode": "NULLABLE",
    "type": "INTEGER",
    "description": null,
    "fields": []
  },

  {
    "name": "deid_text",
    "mode": "NULLABLE",
    "type": "STRING",
    "description": null,
    "fields": []
  },

  {
    "name": "bounding_boxes",
    "mode": "NULLABLE",
    "type": "STRING",
    "description": null,
    "fields": []
  },
  
  }
]

Simple search - Example using lung nodules

The great thing about Atlas is its multiplicity of terms to get the same output. Here's an example of what searching for lung nodules looks like:

Here we search for lung nodules OR chest OR thorax OR mass. Here's another example of looking for lung nodules:

Another complex search: Example using brain mirco- hemorrhage

Here we look for micro-bleeds. That would like this in Atlas:
