The main portion of the app shows the live ultrasound scan. It provides controls to the user to filter the scan (e.g. change brightness, scan modes, depth, scan frequency). User can select from previously saved scans to view. User can freeze scan to save image, record a video of the live scan, and save metadata attached to the saved image/video (e.g. Patient ID, name, age, scan type). The user can export the file, eventually select from other file format options.
There is pretty much just the main screen where the user interacts with the scan. They can bring up quick screens, like to select from old scans to look at, or to add/edit data attached to a scan, or to modify more advanced controls.
Mainly the user will be watching the scan on the iPad while their other hand controls the probe device on the patient. They will likely use the depth and gain controls the most while using the probe. If they see something important, they may pause the scan and rewind to recent frames to look at something in particular. When they do that, they will be able to individually look through recent images, or watch a video of the recent images in series. If they like the video or a particular image, it can be saved.
When an image or video is saved(this will be called the scan), they need to be shown a dialog/modal/new screen and have a small form to fill out to add data to the scan. They will add a patient ID, patient name, type of scan, as well as notes they want to make about it.
Saved scans will be able to be shown back to the user at any point, and they should be able to edit the data they filled out for it or delete the scan if it isn't relevant anymore.
