Summary[edit]
DescriptionSet of 16 prototype electrodes for applied potential tomography (APT), 1987. (9663810916).jpg |
English: This apparatus was developed by Professor B H Brown at the Royal Hallamshire Hospital, Sheffield, England. In APT, now renamed electrical impedence tomography, electrodes attached to the body apply tiny electrical signals, which other electrodes pick up. Changes in the strength and timing of these signals are analyzed by computer to create an image. The electrodes are illustrated attached to a grapefruit which is standing in for a child's head and liquid is injected into the 'head' to mimic a brain haemorrhage.
Deutsch: Dieses Gerät wurde von Professor B. H. Brown am Royal Hallamshire Hospital in Sheffield, England, entwickelt. Bei der APT, jetzt umbenannt in elektrische Impedanztomographie, liegen am Körper angebrachte Elektroden winzige elektrische Signale an, die von anderen Elektroden aufgefangen werden. Änderungen in der Stärke und im Timing dieser Signale werden von einem Computer analysiert, um ein Bild zu erzeugen. Die Elektroden sind an einer Grapefruit befestigt, die den Kopf eines Kindes darstellt, und es wird Flüssigkeit in den "Kopf" injiziert, um eine Hirnblutung zu simulieren. |
