"Magnetopneumography needs inversion of weak magnetic data in order to estimate amount and spatial distribution of ferromagnetic dusts deposited in lungs of metal workers. Our continuously improved setup is sensitive enough to detect remanent fields of small amounts (<8 mg) of magnetite dust. Fluxgate probes as the best room-temperature sensors are used. Estimation of distribution of 35 unit cubes of a simplified phantom based on SVD calculated calibration inverse matrix is demonstrated here. We still cope with background noise and positioning errors that severely limit the results. Preparation of electronic calibration phantom should enable successful inversion of more complex sources." . . "Magnetopneumography - Real-World Phantom Inversion" . "2"^^ . . "147816" . .
