Medical - Medical: Dentistry / CO2 Laser Ablation | | German term or phrase: Bahnkreuzung | Bei gleicher Zeitdauer (1 s) kann dagegen das entsprechende Areal im cw-Betrieb immer noch 10-mal bestrahlt werden.2 Zudem beschreibt der Scanner eine sog. Lissajousche Bahnfigur, bei der es zu ***Bahnkreuzungen*** kommt. An Stellen der ***Bahnkreuzungen*** besteht eine höhere Wahrscheinlichkeit für eine mehrfache Applikation von Laserpulsen, während in benachbarten Arealen bisweilen keine Pulse auftreffen.7 Damit ist erklärbar, dass Zonen dysplastischer Zellen an der Oberfläche nicht vom Laserstrahl erfasst werden und somit überleben."
From a text about CO2 laser ablation. What exactly is a Bahnkreuzung here? Path crossing? Path intersection? Maybe just intersection on its own? TIA for your help. |
| | Clarification request(s) and responseRowan Morrell (asker): 5:31am Dec 6, 2004: Thank you - But WHY do you think it's "path crossing" in this particular context? Some explanations or references would help a great deal. Just proposing an answer without backing it up with some arguments or references doesn't really help at all.
Rowan Morrell (asker): 7:35am Dec 6, 2004: Thanks Meturgan - I don't mind guesses if they're backed up by an explanation and/or references, which you've done, so thanks for that. I do tend to think that "intersection" is more likely than "path crossing", but the "Bahn" bit makes me a bit uncertain.
Rowan Morrell (asker): 8:38am Dec 6, 2004: Pretty convincing added note - I'm beginning to think I should have asked this under Mathematics, though. :-) But thanks again. Protradit, take note of Meturgan's answering style and try to emulate it in the future. Make a case for your answer, even if you're not sure.
Rowan Morrell (asker): 9:28am Dec 6, 2004: Whole phrase - Come to think of it, how would you translate the whole phrase, "bei der es zu Bahnkreuzungen kommt"? The meaning isn't too clear to me at all.

| | intersection(s) of the Lissajous curves / Lissajous figures | Explanation:
I found something that might help you. It's just a guess.
http://www.math.com/students/wonders/lissajous/lissajous.htm...
Before the days of digital frequency meters and phase-locked loops, Lissajous figures were used to determine the frequencies of sounds or radio signals. A signal of known frequency was applied to the horizontal axis of an oscilloscope, and the signal to be measured was applied to the vertical axis. The resulting pattern was a function of the ratio of the two frequencies.

Pedal curve : Given a curve C then the pedal curve of C with respect to a fixed point O (called the pedal point) is the locus of the point P of intersection of the perpendicular from O to a tangent to C.

Lissajous figure, also called Bowditch Curve, is a pattern produced by the intersection of two sinusoidal curves the axes of which are at right angles to each other. First studied by the American mathematician Nathaniel Bowditch in 1815, the curves were investigated independently by the French mathematician Jules-Antoine Lissajous in 1857–58. www.britannica.com/eb/article?tocId=9048492
Lissajousche Bahnfigur = Lissajous figure = Lissajous curve
Bahnkreuzungen = intersections of the Lissajous figure / Lissajous curve
[0034] If one associates each intersection of the Lissajous figure with an image point, i.e. a point on the image field at which a light point 35 with desired brightness is to be created by modulation of the light beam 18, in order to result in the image to be projected together with other image points, and counts each reversal point as half an intersection, the following applies for the number N of the image points defined in this way:
