A taught hour per specialty — diagrams, a live simulation, and a human reading in four languages.
- 00 Foundations
How a photon dies in tissue
Three ways a photon can vanish — and why the one that wins depends on energy and atomic number.

- 01 Therapy
From isocenter to monitor units
Inverse square, percent depth dose, and the MU you will actually type.

- 02 Imaging
Dose indices you will be asked
CTDI, DLP, SSDE, and why a single CTDI is not the patient's dose.

Activity, wait, and the number on the report
Decay is not a nuisance. It is the clock of every elution, every SUV, every delayed image.

- 04 Protection
Time, distance, shielding — then the wall
The three controls you already know, written so a barrier calculation has a place to start.

- 05 Biology
Fractionation is a language
Linear-quadratic survival, BED, and EQD2 — how a 2-gray fraction and a 8-gray fraction stop being comparable until you convert.

- 06 Dose
From charge in a cavity to gray in water
Bragg–Gray, TG-51, kQ and kTP — the chain that turns a coulomb into absorbed dose.

- 07 MRI
A clock, a tip, a recovery
Larmor frequency, the RF tip, and T1/T2 — contrast is a timing choice.

- 08 Ultrasound
A click, an echo, a shift
Impedance sends the echo home. Time is depth. Motion is Doppler. That is the whole craft.
