. Imaging. along. a. blood. vein. of. a. chicken. wing.. (a)-(d). imaging. of. the.
chicken. wing. blood. veins. at. different. locations.. The. solid. arrows. indicate. the. blood. vein,. while. the. dashed.

Figure. 26.9. shows. imaging. along. a. blood. vein. of. a. chicken. wing.. Although. the. micro.
probe.diameter.is.equal.to.200.μm,.a.construction.of.a.larger.image.can.be.easily.obtained.
with.real-time.processing..This.can.be.done.by.calculating.the.relative.movement.of.the.
multi-axis.platform.where.the.micro.probe.is.located.and.converting.it.to.the.image.move-
ment..Each.one.of.the.presented.images.shows.a.different.location.of.the.micro.probe.along.
the.imaged.blood.vein..In.fact,.from.the.visualization.point.of.view,.the.images.are.indi-
vidually.shown.instead.of.being.cascaded.into.a.single.image..The.solid.arrows.indicate.
the.blood.vein,.while.the.dashed.arrows.as.well.as.the.labeling.letter.indicate.the.cascad-
ing.point.between.the.sub-images.presented.in.Figure.26.9.(similar.to.the.process.shown.in.
Figure.26.5b)..By.proper.cascading,.images.of.a.full.length.of.the.examined.area.of.interest.
(e.g.,.blood.vein).can.be.easily.obtained.
Figure. 26.10. shows. the. experimental. setup. used. for. imaging. from. the. inside. of. a. rat.
brain..The.setup.includes.two.main.modules..The.irst.module.is.a.special.rat.holder.that.
is.used.to.hold.the.rat.during.the.surgery.and.the.experiment's.processes,.and.the.second.
module. is. related. to. a. platform. that. enables. the. accurate. navigation. of. the. micro. probe.
inside.the.examined.area.
