There is disclosed electrical impedance tomography apparatus adapted to detect abnormalities in bodily matter comprising: electrical signal generating means for generating electrical signals at a plurality of frequencies; an electrode arrangement for applying the electrical signals to the bodily matter and detecting electrical impendance properties of the bodily matter; and data processing means for correlating the detected electrical impedance properties with the presence or absence of abnormalities in the bodily matter; in which electrical signals of a frequency greater than 1 MHz, preferably greater than 2 MHz, more preferably greater than 3 MHz and most preferably greater than 4 MHz are applied to the bodily matter.

Apparatus and method for detecting abnormalities in bodily matter

A method for reproducing an integral, panoramogramic or full spatial image for viewing using a decoding screen as a 3-D picture comprising representing the image as an array of image points with a density corresponding to high resolution ink printing.

Producing visual images

There is disclosed a method for storing and/or transmitting 3D image information comprising the steps of: producing an image to be stored and/or transmitted comprising an array of strongly correlated neighbouring sub-images; casting the sub-images on to a pixel screen capturing the sub-images as electronic data; compressing the electronic data by eliminating redundancies associated with the sub-images; storing and/or transmitting the compressed data; the compression being reversible so as to expand the data to re-create the sub-images for viewing as a 3D image through an optical viewing system comprising a microlens or lenticular array.

The invention relates to the production of three dimensional images for direct viewing or for recording on a sensitized recording surface. The invention provides a method and apparatus for the direct production of integral parallax orthoscopic panoramagramic images, which objective is met by a process comprising directing at an object a means of gathering and focussing incoming radiation from the object of a wavelength to which said means is suited, positioning to either side of said gathering and focussing means a grouping means for producing a number of groups of individual waves, each group emanating from a part of said object, said grouping means generating an image in pseudoscopic form, and a means of encoding the pseudoscopic image as discrete parallactic information on a single plane, for subsequent viewing as an orthoscopic image.
