# Measurement Tracking
|
||||
|
||||
## Introduction
|
||||
OHIF-V3's `Basic Viewer` implements a `Measurement Tracking` workflow. Measurement
|
||||
tracking allows you to:
|
||||
|
||||
- Draw annotations and have them shown in the measurement panel
|
||||
- Create a report from the tracked measurement and export them as DICOM SR
|
||||
- Use already exported DICOM SR to re-hydrate the measurements in the viewer
|
||||
|
||||
|

### Tracked vs Untracked Measurements
|
||||
|
||||
`OHIF-v3` implements a workflow for measurement tracking that can be seen below.
|
||||
|
||||

|
||||
|
||||
In summary, when you create an annotation, a prompt will be shown whether to start tracking or not. If you start the tracking, the annotation style will change to a solid line, and annotation details get displayed on the measurement panel.
|
||||
On the other hand, if you decline the tracking pormpt, the measurement will be considered "temporary," and annotation style remains as a dashed line and not shown on the right panel, and cannot be exported.
|
||||
|
||||
|
||||
Below, you can see different icons that appear for a tracked vs. untracked series in
|
||||
`OHIF-v3`.

||||

### Reading and Writing DICOM SR
|
||||
|
||||
`OHIF-v3` provides full support for reading, writing and mapping the DICOM Structured
|
||||
Report (SR) to interactable `Cornerstone Tools`. When you load an already exported
|
||||
DICOM SR into the viewer, you will be prompted whether to track the measurements
|
||||
for the series or not.
|
||||
|
||||

|
||||
|
||||
If you say no and later decide to say yes, click on the SR button the prompt will come again
|
||||
|
||||
click to restore measurements
|
||||
If you click Yes, DICOM SR measurements gets re-hydrated into the viewer and
|
||||
the series become a tracked series. However, If you say no and later decide to say track the measurements, you can always click on the SR button that will prompt you
|
||||
with the same message again.
|
||||
|
||||

|
||||
|
||||
The full workflow for saving measurements to SR and loading SR into the viewer is shown below.

### Loading DICOM SR into an Already Tracked Series
|
||||
|
||||
If you have an already tracked series and try to load a DICOM SR measurements,
|
||||
you will be shown the following lock icon. This means that, you can review the
|
||||
DICOM SR measurement, manipulate image and draw "temporary" measurements; however,
|
||||
you cannot edit the DICOM SR measurement.
