A system and method of enabling detection enhancements selected from a plurality of detection enhancements. In a system having a plurality of clinical rhythms, including a first clinical rhythm, where each of the detection enhancements is associated with the clinical rhythms, the first clinical rhythm is selected. The first clinical rhythm is associated with first and second detection enhancements. When the first clinical rhythm is selected, parameters of the first and second detection enhancements are set automatically. A determination is made as to whether changes are to be made to the parameters. If so, one or more of the parameters are modified under user control.

A system and method of enabling detection enhancements selected from a plurality of detection enhancements. In a system having a plurality of clinical rhythms, including a first clinical rhythm, where each of the detection enhancements is associated with the clinical rhythms, the first clinical rhythm is selected. The first clinical rhythm is associated with first and second detection enhancements. When the first clinical rhythm is selected, parameters of the first and second detection enhancements are set automatically. A determination is made as to whether changes are to be made to the parameters. If so, one or more of the parameters are modified under user control. laim 1, wherein said step (f) uses the iterative correction method, comprising the steps of: (f)(1) inputting 1104 image data on the sample 204 and a guess of the electrical properties values of the sample 204; (f)(2) generating experimental Fourier transform values 1106; (f)(3) generating a Fourier transform derivative matrix 1108; (f)(4) generating theoretical Fourier transform values 1110; (f)(5) calculating corrections 1112 to said guess of the electrical properties values of the sample 204, (f)(6) determining whether said corrections are within an acceptable limit 1114; and (f)(7) generating a new guess of the electrical properties values 116 of the sample 204 by adding said corrections to said guess electrical properties and returning to step (f)(4), if it is determined in step (f)(6) that said corrections are not within said acceptable limit. 7. The method according to claim 1, further comprising the step of: (h) triggering said step (e) upon the completion of said step (d). 8. The method according to claim 1, further comprising the step of: (h) triggering said step (e) when noise associated with the sample 204 is minimized. 9. The method according to claim 8, wherein the sample 204 is a human subject and said triggering of said step (h) occurs at an appropriate cardiac cycle of the human subject. 10. The method according to claim 8, wherein the sample 204 is a human subject and said triggering of said step (h) occurs at an appropriate pulmonary cycle of the human subject. 11. A computer program product for use with a computer system of an Electrical Property Enhanced Tomography (EPET) apparatus for providing information of the electrical properties of a sample being measured with a tomographic device, which comprises: a computer usable medium having computer readable program code means embodied in said medium for generating object code for a computer, said computer readable program code means having: a first computer readable program code means for operating the computer system to control an electromagnetic field in a sample holder by applying frequency dependent voltages of predetermined amplitude to an array of sensors that form a surface to be placed in electrical connection with the sample, such that time dependent net total electric charges are produced on the surface of the sample holder; a second computer readable program code means for operating the computer system to determine the time dependent net total electric charges on the surface of the sample holder while the sample is not present in the sample holder to thereby generate empty data values; a third computer readable program code means for operating the computer system to input initial Image data from the tomographic device when the sample is placed in the sample holder; a fourth computer readable program code means for operating the computer system to determine the time dependent net total electrical charges on the surface of the sample holder when the sample is within the sample holder, thereby generating full data values; a fifth computer readable program code means for operating the computer system in response to the generated empty data values, the received initial image data, and the generated full data values to produce enhanced information on the electrical properties of the sample; and a sixth computer readable program code means for operating the computer system to output said enhanced information on the electrical properties of the sample. 12.
