Abstract
Description
Die Erfindung gehört dem technischen Gebiet der Medizinfor schung mit thermischen Verfahren an.The invention belongs to the technical field of medicine with thermal processes.
Die üblichen thermographischen Untersuchungen wurden bisher unter nicht einwandfreien physikalischen Versuchsbedingungen in nicht klimatisierten, nicht abgeschirmten Versuchsräumen durchgeführt.The usual thermographic examinations have so far been under impeccable physical test conditions in non-air-conditioned, unshielded test rooms carried out.
Es wird zwar vor und/oder nach einmaliger Erwärmung bzw. Ab kühlung der Hautoberfläche die sich einstellende Temperatur verteilung auf der Haut mittels Thermographieverfahren beob achtet und registriert und statistisch ausgewertet, jedoch ist eine Kombination dieser Meß- und Auswerteverfahren mit der in der Erfindung vorgestellten schwingungsförmigen, defi nierten Erwärmung der Haut am Tumor und fernab davon aus der Literatur nicht bekannt.It is true before and / or after a single heating or starting cooling the skin surface the temperature that arises Observe distribution on the skin using a thermography process respects and registers and statistically evaluated, however is a combination of these measurement and evaluation methods with the oscillatory, defi presented in the invention heating of the skin on the tumor and far away from it Literature not known.
(Hefte 3, (Juli 1994), 4 (Oktober 1994), 1 (Januar 1995) mit computergestützter Literaturrecherche zur Thermographie all gemein mit 141 ausgewerteten Literaturstellen, beziehbar über Dr. K. Ammer, Ludwig Boltzmann Forschungsstelle für Physika lische Diagnostik, Hanuschkrankenhaus, Heinrich Collin Str. 30, A - 1140 Wien/Austria).(Issues 3, (July 1994), 4 (October 1994), 1 (January 1995) with computer-assisted literature research on thermography all together with 141 evaluated references, available from Dr. K. Ammer, Ludwig Boltzmann Research Center for Physics Diagnostics, Hanusch Hospital, Heinrich Collin Str. 30, A - 1140 Vienna / Austria).
Das der Erfindung zugrundeliegende Problem betrifft ein Ver fahren zur sicheren Frühdiagnostik von Karzinomen mit thermi schen Verfahren, bei dem die Hautoberfläche zeitabhängig - schwingungsförmig - erwärmt wird und die sich am Tumor und fernab davon ausbildende Oberflächentemperaturverteilung als Funktion der Zeit bis zum quasistationären Endzustand regi striert und am Ende mit Hilfe statistischer Verfahren ausge wertet wird.The problem underlying the invention relates to a Ver drive to the safe early diagnosis of carcinomas with thermi procedure in which the surface of the skin is vibrating - is heated and which is on the tumor and far from it forming surface temperature distribution as Function of time until quasi-steady state regi strated and in the end with the help of statistical procedures is evaluated.
Anschließend wird eine Patientenstatistik geführt. Gut- und bösartige Tumore unterscheiden sich durch unter schiedliche thermoregulatorische Vorgänge im durchbluteten Gewebe, so daß eine deutlich verbesserte Frühdiagnostik von Karzinomen zu erwarten ist.Subsequently, patient statistics are kept. Benign and malignant tumors differ by different thermoregulatory processes in the blood supply Tissue, so that a significantly improved early diagnosis of Carcinoma is expected.
