How to use it
- Move through slices with the mouse wheel, by dragging up or down on the image, with the slider or with the arrow keys. On a phone, swipe up or down on the image.
- Names of the structures in the slice sit beside the image, with a line to each. Point at a name, or at the image, to highlight the structure; click or tap a name to keep it highlighted. On a phone the names are numbered on the image and listed under it.
- Axial and coronal images name one side at a time: choose the patient’s left or right. Group buttons turn names on or off; the cerebral cortex starts off because its gyri fill every slice.
- Click or tap the image to set the crosshair; the other planes move to that point. Search for a structure to jump to its largest cross-section.
- Quiz: “Find it” asks you to click a structure; “Name it” highlights one and offers four names. Names stay hidden during a question unless you reveal them, which scores no point. Your best score for each setting stays in this browser only.
- With an image selected: ↑ ↓ and Page Up Page Down move through slices; Shift with an arrow key moves the crosshair; Enter highlights the structure at the crosshair (in “Find it”, answers), Esc clears it and L shows or hides the labels. In “Name it”, 1–4 choose an answer.
About the images
Axial and coronal images follow the radiological convention: the patient’s right is on the viewer’s left. Sagittal images have anterior on the left. Letters at the image edges show the directions.
