Summary

Authors:Brian Brown Date:27th November 1981Brief Description:Data were recorded from Rod Smallwoood's arm on the 27th November 1981; the dot matrix image which shows the ulna and radius bones. We made a 'radiotherapy type' mould of the arm and then put drawing pins through the plastic (pin head inwards) as electrodes. There two sets of data. One is recorded from the arm and the other is with saline filling the mould.

The data were published in: D.C. Barber, B.H. Brown, and I.L. Freeston, "Imaging spatial distributions of resistivity using applied potential tomography", Electronics Letters, 19(22):933-935, 1983 http://digital-library.theiet.org/content/journals/10.1049/el_19830637

Format:Data are handwritten and scanned into the linked pdf file. The adjacent drive/receive data sets for both the Uniform(Saline) and Arm data and these are included in the attached Excel file. The are 6 columns of data in the xls file. The first three are for the uniform case and give the two reciprocal data sets and the mean of the two. Columns 4-6 are for the arm. I did a quick reconstruction using columns 3 and 6 as ref and data respectively and it looked OK.

Methods:The pdf file that is attached shows the line printer output of the data we recorded from Rod Smallwoood's arm on the 27th November 1981 and the dot matrix image which shows the ulna and radius bones. We made a 'radiotherapy type' mould of the arm and then put drawing pins through the plastic (pin head inwards) as electrodes. There two sets of data. One is recorded from the arm and the other is with saline filling the mould. The pdf file also shows my plot of the XY position of the electrodes.

Now the data set on the line printer is a complete data set i.e. Drive 1/2 then 1/3 then 1/4 etc for every combination. I could only find the print out for one of the data sets. However, I found my notebook with the adjacent drive/receive data set and this is page 7 of the pdf file.

I have extracted the adjacent drive/receive data sets for both the Uniform(Saline) and Arm data and these are included in the attached Excel file. The are 6 columns of data in the xls file. The first three are for the uniform case and give the two reciprocal data sets and the mean of the two. Columns 4-6 are for the arm. I did a quick reconstruction using columns 3 and 6 as ref and data respectively and it looked OK.

The first column of data is 104 point as follows.

Drive 1/2 receive 3/4 Drive 1/2 receive 4/5 etc Drive 1/2 receive 16/1 Drive 2/3 receive 4/5 Drive 2/3 receive 5/6 etc Drive 2/3 receive 16/1 Drive 4/5 receive 6/7 Drive 4/5 receive 7/8 etc Drive 4/5 receive 16/1 etc etc Drive 14/15 receive 16/1

The second column is the other reciprocal set.

I think these data are the ones used to produce the image in the Electronics Letters paper of 1983 - page 1 of my pdf file.
