## Study Summary

of the study will shows up.

![user-study-summary](../../assets/img/user-study-summary.png)

As you can see, a summary of series available in the study is shown, which contains
the series description, series number, modality of the series, and instances in the series.

Next, We will discuss the modes, and their enabled/disabled states.


## Study Specific Modes
As seen for each study, all the available modes will get shown. What is a mode?
Modes define the higher-level functionalities and appearance for the viewer.
For instance, as seen, there are two modes shown for the selected study

- Basic Viewer: Default mode that enables rendering and measurement tracking

- PET/CT Fusion: Mode for visualizing the PET CT study in a 3x3 format.

However, based on the mode configurations (e.g., available modalities), they can be
enabled or disabled.

Below, you can see two studies, In Study 1, Basic Viewer mode is enabled and
ready to be used; however, the PET/CT fusion is disabled by the viewer since
only PET images are found in the study.
