Abstract

The electrical resistivity of various tissues is known to cover a wide range of values and images of resistivity distribution within a patient should show good contrast and may prove to have some diagnostic use. Data on the internal distribution of resistivity within a patient may be obtained by applying current between electrodes attached to the patient and measuring the voltage developed across the surface of the patient. After collection of a complete set of data a tomographic image of resistivity may be constructed using a filtered back-projection algorithm. Some likely clinical uses are in the assessment of respiratory function and cardiopulmonary dynamics.
