Abstract
Description
Die Neuerung bezieht sich auf ein System für die Fluoreszenzdiagnostik gemäß dem Oberbegriff des Patentanspruches 1.The Innovation refers to a system for fluorescence diagnostics according to the preamble of Claim 1.
Die Fluoreszenzdiagnostik ist als ein noch experimentelles, klinisch nicht zugelassenes Verfahren grundsätzlich bekannt, welches u.a. auch für die quantitative Früherkennung einer Vielzahl von präkanzerosen/dysplastischen Veränderungen an Geweben sehr viel versprechend ist. Die Fluoreszenzdiagnostik macht sich die Stoffwechselunterschiede beispielsweise im Porphyrinstoffwechsel zwischen Zellen in dysplastischem/tumorösem Gewebe und Zellen im normalen Gewebe zunutze.The Fluorescence diagnosis is still experimental, clinical Unauthorized method basically known, which u.a. also for the quantitative early detection a variety of precancerous / dysplastic changes in tissues is very promising. Fluorescence diagnostics makes the metabolic differences, for example, in porphyrin metabolism between cells in dysplastic / tumorous tissue and cells in normal Utilize tissue.
Aufgabe der Neuerung ist es, ein System aufzuzeigen, mit dem eine verbesserte und eindeutigere Fluoreszenzdiagnostik möglich ist. Zur Lösung dieser Aufgabe ist ein System entsprechend dem Patentanspruch 1 ausgebildet.task The innovation is to show a system with which an improved and clearer fluorescence diagnostics is possible. To solve this Task is a system according to claim 1 formed.
Das Neuerungsgemäße System dient zur Visualisierung von Fluoreszenzfarbstoffen zur Fluoreszenzdiagnostik u.a. von humanen Tumoren, ist speziell auch für eine hochsensitive, quantitative Früherkennung einer Vielzahl von präkanzerosen/dysplastischen Veränderungen geeignet und nutzt dabei beispielsweise den Unterschied im Porphyrinstoffwechsel bei Zellen in dysplastischem/tumorösem Gewebe im Vergleich zu Zellen im normalen Gewebe. Das neuerungsgemäße System gestattet weiterhin ein sehr vereinfachtes Arbeiten bei hoher Sensitivität und eindeutigen Ergebnissen.The New system serves for the visualization of fluorescent dyes for fluorescence diagnostics et al of human tumors, is also specific to a highly sensitive, quantitative early detection a variety of precancerous / dysplastic changes suitable and uses, for example, the difference in porphyrin metabolism in cells in dysplastic / tumorous tissue compared to Cells in normal tissue. The renewal system continues to allow a very simplified working with high sensitivity and clear Results.
Als Fluoreszenzfarbstoffe eignen sich u.a. Fluorophore, die Licht im sichtbaren Spektralbereich oder nahen Infrarotbereich absorbieren und Licht im nahen Infrarotbereich emittieren. Zu diesen Fluorophoren zählen insbesondere auch exogene Farbstoffe, d. h. von außen in das Gewebe eingebrachte Farbstoffe, wie z. B. Indocyaningrün und verschiedene Porphycene, aber auch endogene Farbstoffe, d.h. im Gewebe erzeugte Farbstoffe, wie z. B. 5-Aminolävulinsäure induzierte Porphyrine (insbesondere Protoporphyrin IX) usw.When Fluorescent dyes are suitable i.a. Fluorophores, the light in the absorb visible spectral range or near infrared range and emit light in the near infrared range. To these fluorophores counting especially exogenous dyes, d. H. from the outside into the Tissue introduced dyes such. B. indocyanine green and various Porphycenes, but also endogenous dyes, i. generated in the tissue Dyes, such as. B. induced 5-aminolevulinic acid Porphyrins (especially protoporphyrin IX) etc.

Durch eine entsprechend kurze Aufnahmezeit für die Fluoreszenzbilder kann das Umgebungslicht aus diesen Bildern soweit diskriminiert werden, daß das System bei ständigem Umgebungslicht, d. h. auch bei während der Anregungs- und Fluoreszenzphase vorhandenem Umgebungslicht eindeutig arbeitet.By a correspondingly short recording time for the fluorescence images can the ambient light from these images are discriminated so far that the system at constant Ambient light, d. H. also during during the excitation and fluorescence phase existing ambient light clearly is working.
