Vocal function following laser and conventional surgery of small malignant vocal fold tumours
1996
AbstractIn the disecribed study, 26 patients after conventional, and 27 patients after laser cordectomy were examined six months or more after the operation. Videolarybogstroboscopy revealed that patients after laser cordectomy more often phonate on a purely glottic level (81 per cent) in comparison to patienbts after conventional cordectomy (19 per cent). Webs were more frequent and more extended after conventional cordectomy compared to endoscopic laser surgery. The maximal phonation time showed a very wide range with a mean value of 9 to 10 sec; there was no statistical difference between the groups of patients. Using yanagihara's classification of sonograms, a better voice quality was m…
Stroboscopic XMCD-PEEM Imaging
2007
Abstract This article summarizes recent results on magnetization dynamics obtained with time-resolved photoemission electron microscopy (PEEM) using X-ray magnetic circular dichroism as contrast mechanism. Time resolution is performed by a stroboscopic technique that is exclusively sensitive to reversible processes, but offers a very high time resolution only limited by the X-ray pulse width. A time resolution of 20 ps in combination with a lateral resolution of 100 nm has been achieved.
