Abstract

Method for generation of thermographic images of objects, especially human or animal bodies, wherein an algorithm is used to compensate for different cooling periods, or de-image times, of the body during recording of thermographic images so that a static image can be obtained that is useful for diagnostic purposes.

Description

Die Dynamik der Bildfolge ist als eine Folge der Veränderung der Temperatur des aufzunehmenden Gegenstandes oder Körperteils erklärt. The dynamic of the image sequence is as a result of the change in Temperature of the object or body part to be recorded explained.

Das Problem besteht darin, aus dieser dynamischen Bildfolge irgendwann oder irgendwo im Verlauf der Bildfolge einen Punkt x zu finden von dem aus im Verlauf der weiteren Bildfolge immer der Punkt (oder das Bild) y rechnerisch ermittelt werden kann. The problem is from this dynamic image sequence a point x at some point or somewhere in the course of the image sequence from there always find the Point (or the image) y can be calculated.

x wird gefunden unter Berücksichtigung der Grundwärme des zu untersuchenden Gegenstandes oder Körperteils. Weiterhin unter Berücksichtigung der Konstanz und Intensität und gleichmäßigen Flächigkeit der Kühlung und letztlich der Empfindlichkeit des thermooptischen Sensors. x is found taking into account the basic heat of the examining object or body part. Continue at Consideration of constancy and intensity and even Flatness of the cooling and ultimately the sensitivity of the thermo-optical sensor.

Schrittfolge A (s. Fig. 1)Step sequence A (see Fig. 1)

  • A) Kontakt von b) mit dem Gegenstand a); Ergebnis: Es entsteht auf dem Sensor b) ein Ausgangsbild: DIT Image-0 (DIT-0) A) contact of b) with object a); Result: It arises an output image on sensor b): DIT Image-0 (DIT-0)
  • B) Kontakt von Kühlschild c) mit dem Sensor b) und indirekt mit dem Gegenstand oder Körperteil a); Ergebnis: Es entsteht eine Bildfolge wobei die bildlich dargestellten Anteile mehr oder weniger schnell von der Fläche des Sensors verschwinden bis sich letztlich keine Wärme mehr darstellt. Dieses Bild nennen wir DIT Image-x (DIT-x). B) Contact of the cooling shield c) with the sensor b) and indirectly with the object or body part a); Result: One is created Image sequence with the parts shown more or disappear less quickly from the surface of the sensor ultimately no heat is present. Name this picture we DIT Image-x (DIT-x).
ErklärungExplanation

Die Zeit von DIT-0 bis DIT-x nennen wir DIT oder deimage-time. Diese Zeit kann in sec. gemessen werden. Die DIT gibt Auskunft über die Grundwärme des zu untersuchenden Körperteils Die Grund wärme des zu untersuchenden Körperteils kann zu verschiedenen Zeiten der Untersuchung bei ein und derselben zu untersuchenden Person und ein und desselben zu untersuchenden Körperteils unterschiedlich sein. Deshalb ist es möglich, dass die DIT immer von der Erstuntersuchung abweichende Werte ergibt(z. B. die Zeit vor und nach der Regel der Frau). Aber auch emotionale Dinge können sich auf die Grundwärme und somit auf die DIT auswirken. Ebenfalls hat die Umgebungstemperatur Auswirkungen auf die Grundwärme des Körperteils und somit auf die DIT. We call the time from DIT-0 to DIT-x DIT or deimage-time. This time can be measured in seconds. The DIT gives Information about the basic heat of the body part to be examined The basic heat of the body part to be examined can different times of examination at one and the same examining person and one and the same to be examined Body part to be different. It is therefore possible that the DIT always gives different values from the initial examination (e.g. the Time before and after the woman's rule). But also emotional things can affect the basic heat and therefore the DIT. The ambient temperature also affects the Basic heat of the body part and thus on the DIT.

Schrittfolge B (s. Fig. 1)Sequence of steps B (see Fig. 1)

I. Sofort nach Entstehung des Bildes (DIT-x) beginnt durch Entfernung des Kühlschildes (c) die RIT oder re-image-time. Das erste Bild der RIT wird bezeichnet mit RIT-Image-0 (RIT-0). I. Immediately after the image (DIT-x) has been created Removal of the cooling shield (c) the RIT or re-image time. The The first image of the RIT is called RIT-Image-0 (RIT-0).

II. Nach einer sich aus der DIT zu errechnenden Zeit wird bei Erreichen des Bildes RIT-Image-y (RIT-y) der Vorgang mit einer automatisch ausgelösten Digital-Aufnahme abgeschlossen II. After a time to be calculated from the DIT, at RIT-Image-y (RIT-y) the process with a automatically triggered digital recording completed

ErklärungExplanation

Die Zeit, in der sich auf dem thermooptischen Sensor (b) ein neues Bild aufbaut nennen wir RIT oder re-image-time. Diese Zeit reicht von dem ersten Bild aus dieser Phase (RIT-0) bis zu dem letzten Bild aus dieser Phase (RIT-y). Die Zeit für die RIT errechnet sich aus der DIT. The time in which there is a new one on the thermo-optical sensor (b) We call image building RIT or re-image-time. That time is enough from the first image from this phase (RIT-0) to the last image from this phase (RIT-y). The time for the RIT is calculated from the DIT.
