Machines
Each equation is pinned to the part of the machine where it is used — then a working schematic shows the physics in motion.
Linear accelerator
C-arm linac in the bunker — monitor chamber, MLC, and the beam at isocenter.
58 eq.·How it works
CT scanner
Diagnostic CT — tube and detectors in the gantry, dose along the scanned length.
7 eq.·How it works
MRI scanner
Wide-bore magnet — B₀, gradients, and the RF coil on the patient.
23 eq.·How it works
PET/CT
Hybrid scanner — coincidence ring behind, CT for attenuation in front.
16 eq.·How it works
Gamma camera
Dual-head SPECT — crystal, PMTs, and the collimator facing the patient.
6 eq.·How it works
Radiography room
Ceiling tube, table, and wall Bucky — geometry, technique, and detector dose.
25 eq.·How it works
Ultrasound
Probe on tissue — impedance, Doppler, and the console that sets PRF and MI.
21 eq.·How it works
Mammography unit
C-arm with compression paddle — target/filter and average glandular dose.
1 eq.·How it works
Brachytherapy suite
HDR afterloader and C-arm — source in the safe, dwell in the applicator.
4 eq.·How it works
Water phantom
Scanning tank under the linac — TG-51 / TRS-398 reference dosimetry.
20 eq.·How it works
Treatment vault
Maze and barriers — time, distance, shielding, WUT, and weekly dose.
18 eq.·How it works
Hot lab
Generator, dose calibrator, and L-block — activity, breakthrough, Marinelli.
12 eq.·How it works
Proton gantry
Nozzle and snout — residual range, RBE 1.1, and the Bragg peak in the patient.
