EIT data of a human arm
收藏资源简介：
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 License:Creative Commons Artistic License (with Attribution)Attribution Requirement:Use or presentation of these data reference this publication: 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 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.
作者：布莱恩·布朗（Brian Brown）；日期：1981年11月27日 简要说明：本数据集采集自罗德·斯莫尔伍德（Rod Smallwood）的手臂，采集时间为1981年11月27日，附带一张显示尺骨与桡骨的点阵图像。研究团队先制作了该手臂的放疗固定模具，随后将图钉穿过塑料基材（钉头向内）作为电极。本数据集包含两组数据：一组采集自真实手臂，另一组则是向模具中填充生理盐水后的采集数据。本数据集已发表于以下文献：D.C. Barber、B.H. Brown与I.L. Freeston，《利用应用电位断层成像技术成像空间电阻率分布》，《电子学快报（Electronics Letters）》，19(22):933-935，1983年，链接：http://digital-library.theiet.org/content/journals/10.1049/el_19830637 许可协议：知识共享署名艺术许可协议（Creative Commons Artistic License，需署名） 署名要求：使用或展示本数据集时，请引用以下文献：D.C.
