Noise and spatial resolution of a real-time electrical impedance tomograph
The Sheffield real-time electrical impedance tomograph produces 25 images per second, using 16 electrodes with adjacent-pair current drive and non-iterative image reconstruction. We describe the data acquisition timing of this instrument and present quantitative measurements of its signal-to-noise r...

Zusammenfassung: | The Sheffield real-time electrical impedance tomograph produces 25 images per second, using 16 electrodes with adjacent-pair current drive and non-iterative image reconstruction. We describe the data acquisition timing of this instrument and present quantitative measurements of its signal-to-noise ratio and spatial resolution. |
