Self-test: planes, sides and conventions
Ten questions, each answered on a real slice of the demo scan. Pick an answer, read why, and follow the link if you want the full explanation.
What the questions cover
Recognising axial, coronal and sagittal slices of the jaw; where the patient's left and right sit on axial, coronal and panoramic images; what the red, green and yellow scout lines mean in the MPR stage; why CBCT grey values are not Hounsfield units; and the two rules of tracing an arch for a panoramic reconstruction.
Read first, if you prefer
Axial, coronal and sagittal planes, radiological orientation conventions, window, level and grey values, and how to read a CBCT scan.
Questions students ask
Do I need the app to take this self-test?
No. The slices on this page come from the same demo scan that ships inside JawAtlas, so you can take the test in the browser and then practise the same things in the app.
Why is the patient's left on the right side of an axial slice?
Axial slices are viewed from the patient's feet, the radiological convention used on clinical workstations and in licensing exams. Facing the patient puts their left on your right.
Is a score of 10 out of 10 a sign I can read CBCT?
It means the conventions are in place, which is the foundation. Reading needs the systematic routine in the guide, practised on whole volumes, not single slices.
