Abstract

The ultrasonic reflectometry is used for monitoring or controlling thermally induced, biological effects. Also using ultrasonic reflectometry with laser radiation, temp. gradients, coagulated or denatured vols. are determined also are used for therapy control or for control of the laser. The medical method of the diagnostic ultrasonic A-scan is used, yet these specific electronic detector units are replaced or supplemented by an integrator technology, e.g. according to the box car principle. The specific detector units are supplemented by a synchronising unit for identifying the patient movements.

Description

Die gezielte Überwärmung begrenzter Gewebevolumina wird als nichtchirurgische Zusatztherapie zur Unterstützung der Chemo- und Radiotherapie eingesetzt. Targeted hyperthermia limited volumes of tissue is used as a non-surgical adjunctive therapy to support chemotherapy and radiotherapy. Darüberhinaus finden laserinduzierte Koagulationsprozesse in der Onkologie (bspw. endoskopische Chirurgie in der Gastroenterologie und minimalinvasiven Chirurgie) sowie der Ophthalmologie (bspw. Glaukombehandlung) ihre Anwendung. In addition, find laser-induced coagulation processes in oncology (eg. Endoscopic surgery in the gastroenterology and minimally invasive surgery) and ophthalmology (eg. Glaucoma treatment) its application. Die klinische Durchsetzbarkeit dieser Therapieformen ist mit der Verfügbarkeit eines Verfahrens zu deren Kontrolle eng verknüpft. The clinical enforceability of these forms of therapy is closely related to the availability of a method for their control.

Unter Hyperthermie versteht man die Überwärmung eines im Körper inneren gelegenen Volumens durch Einstrahlung von hochfrequenten Feldern von außen. Under Hyperthermia is defined as the overheating of a body located in the interior volume by irradiation of high-frequency fields from the outside. Als Signifikanzgröße dient die Temperatur erhöhung im Zielvolumen gegenüber der physiologischen Körper temperatur des Gesamtorganismus. The significance size, the temperature is increase in the target volume relative to the physiological body temperature of the whole organism. Nach dem gegenwärtig geübten Stand der medizinischen Anwendung werden nadelartige Sonden mit einem temperaturempfindlichen Halbleiterelement an ihrer Spitze in den Patienten eingestochen und bis zum Zielvolumen vorgeschoben After the currently practiced standard of medical use needle-like probes are inserted with a temperature-sensitive semiconductor element at its tip into the patient and advanced to the target volume
Es sind Versuche unternommen worden, die erreichte Überwärmung nicht-invasiv nachzuweisen (bspw. Messung der NMR-Relaxations zeiten der Protonen des Zielvolumens, aktive und passive Mikro wellentomografie; einen Überblick bietet [I]). There have been attempts to detect the overheating reached non-invasively (e.g., measurement of NMR relaxation times of protons wave tomography of the target volume, active and passive micro,. An overview provides [I]). Aufgrund der teilweise sich widersprechenden Anforderungen (im wesentlichen: ausreichende Nachweistiefe und -empfindlichkeit, Darstellung der Kontrollparameter in Echtzeit, Kompensation von Störeinflüssen, verursacht durch Patientenbewegungen sowie die Kompatibilität mit dem Hyperthermiesystem) ist bis heute noch kein handhabbares und universell einsetzbares Kontrollsystem bekannt geworden. Due to the sometimes conflicting requirements (basically: sufficient proof depth and sensitivity representation of the control parameters in real time, compensating for interference caused by patient movement, as well as compatibility with the hyperthermia system) has been known up to now, no manageable and universally applicable control system. Es sind auch Versuche publiziert worden, die Änderung der Schallgeschwin digkeit bei Einstrahlung von Ultraschall als Signifikanzgröße zur Temperaturbestimmung heranzuziehen [II]. There have been published and attempts to refer to the change in the speed at Schallgeschwin irradiation of ultrasound as a significance size for determining the temperature [II]. Da sich aber die Schall geschwindigkeit in Abhängigkeit von der Temperatur des biologi schen Materials nur sehr gering und monoton ändert, hat sich daraus kein technisches Meßverfahren ableiten lassen. However, since the sound changes speed very low and monotonous, depending on the temperature of the biological material is, is can be derived from any technical measuring methods.

Erfindungsgemäße Lösung inventive solution

Die Erfindung geht von dem Grundgedanken aus, daß an der Grenz fläche zwischen biologisch - physiologischem Gewebe und erwärmtem Volumen eine Ultraschallreflexion auftritt. The invention is based on the fundamental idea that at the interface between biological - physiological tissue and heated volume of an ultrasonic reflection occurs. Der Amplituden reflexionsfaktor ist als Signal meßtechnisch erfaßbar. The amplitude reflection coefficient is detected by measurement as the signal. Größe und Änderung des Signals im Nachweispfad hängen eindeutig von der Temperaturdifferenz und deren zeitliche Änderung während der Überwärmung ab. Size and modification of the signal in the detection path is clearly dependent on the temperature difference and the temporal change during overheating. Im Bereich der beginnenden irreversiblen Änderung des biologischen Zielvolumens gestattet das erfindungsgemäße Verfahren ein Temperaturauflösungsvermögen von ΔT 0.25 grd. In the region of the beginning of irreversible modification of the biological target volume, the inventive method allows for a resolution of temperature .DELTA.T 12:25 grd. Das Verfahren nach der Erfindung benutzt als Nachweis die Methode des A-Scans diagnostischer Ultraschallgeräte, jedoch wird zur Sicherstellung der geforderten strengen Linearität der Reflexions- Signalamplitude die Ultraschall-Hochfrequenz direkt abgegriffen, von der eingestrahlten Hyperthermie-Hochfrequenz gesäubert und durch eine Elektronik nach dem Prinzip des Box Car-Integrators verarbeitet und dargestellt. The method of the invention used as a detection method of A-scans diagnostic ultrasound devices, however, to ensure the required strict linearity of the reflection signal amplitude is tapped, the ultrasonic high frequency directly, cleaned of the irradiated hyperthermia high frequency and by electronics on the principle the box car integrator processed and displayed.

Um eine quantitative Auswertung auch unter dem Einfluß von Patientenbewegungen zu ermöglichen, darf der Triggerzeitpunkt für die die Darstellung regierenden Größen wie Verzögerungszeit und Fensterbreite nicht am Sendesignal festgemacht, sondern muß am interessierenden Echo selbst verankert werden. To enable quantitative evaluation even under the influence of patient motion, the trigger time for the presentation of ruling the likes of delay time and window width is not fixed to the broadcast signal, but must be anchored to the interest echo itself. Eine Synchronisier einheit verschafft sich aus Flankenwert und -steigung des n-ten Echos den Triggerzeitpunkt des darauffolgenden Echos. A synchronizing unit gives off slope value and pitch of the nth echo the trigger time of the subsequent echoes. Die Eindeu tigkeit des Triggerzeitpunktes wird durch eine Komparatorschaltung sichergestellt. The Eindeu ACTION of trigger time is ensured by a comparator circuit.

Alle Komponenten der Synchronisiereinheit sind analog aufgebaut, wodurch diese zentrale Steuereinheit wie das gesamte Nachweis systems in Echtzeit arbeitet. All components of the synchronization unit are constructed analogously, whereby said central control unit as the entire detection system operates in real time.

Weitere Anwendungen Other applications

Unter medizinischen Hyperthermiebedingungen sind auch diejenigen therapeutischen Verfahren zusammenzufassen, denen Koagulations prozesse zugrunde liegen. Under medical hyperthermia conditions and those therapeutic procedures are summarized, which coagulation processes are based. Die Kongruenz der Anforderungen an ein Kontroll- oder Steuerungssystem bei diesen Behandlungsformen resultiert daraus, daß auch hier Therapierisiko und -wirkung nach den erzeugten Temperaturgradienten sowie der räumlichen Ausdehnung der erzeugten Herde zu bewerten ist. The congruence of the requirements of a control or control system with these forms of treatment results from the fact that therapy risk here and effect to the generated temperature gradients as well as the spatial extent of the herd is produced to evaluate. Zur on line-Messung und geeigneten Darstellung dieser beiden Kriterien am Patienten sind alle Komponenten des erfindungsgemäßen Verfahrens notwendig, wobei die Ultraschall-Arbeitsfrequenz der jeweiligen Aufgabenstellung anzupassen ist. For on-line measurement and appropriate representation of these two criteria the patient all the components of the inventive process are necessary, with the ultrasonic operating frequency is to be adapted to the particular task.

In der endoskopischen und minimal-invasiven Chirurgie werden Laser- und Plasmasysteme zur Koagulation maligner Gewebevolumina eingesetzt. In endoscopic and minimally invasive surgery laser and plasma systems are used for coagulation of malignant tissue volumes. Mit der Festlegung des koagulierten Volumens ist die Frage der örtlichen Abtötung des Tumors sowie die Frage möglicher Tumorabsiedelungen eng verknüpft. By fixing the coagulated volume, the issue of local destruction of the tumor as well as the issue of possible Tumorabsiedelungen is closely linked. Da weder tatsächlich erreichte Temperaturen noch tatsächlich erreichte Eindringtiefen sicher nachweisbar sind, sind beide Verfahren zur curativen Behandlung (bspw. in der gastroenterologischen Chirurgie und der Gynäkologie) bislang nicht anwendbar. Since neither actually reached temperatures have actually reached penetration depths are sure detectable both methods for curative treatment (eg. In gastroenterological surgery and gynecology) are not yet applicable.

Durch Einsatz des erfindungsgemäßen Thermometrieverfahrens hat der Laserchirurg die Möglichkeit, Temperaturgradienten und koagulierte Volumenbereiche on line zu überwachen. By using the Thermometrieverfahrens invention of the laser surgeon has the opportunity to temperature gradients and coagulated volume ranges on line monitor. Daraus resultieren ganz erhebliche Fortschritte für die Therapie kleiner Tumoren im Hinblick auf ambulante Operationsmöglichkeiten ohne ausräumende Exzision und eine Verbreiterung des Anwendungsspektrums. This achieves considerable progress for the treatment of small tumors with regard to possibilities ambulatory surgery without ausräumende excision and broadening the range of applications.

In der Ophthalmologie wird die Laserkoagulation ua bei der Glaukombehandlung (transskerale Cyclophotokoagulation TSCPC) und zu Fehlsichtigkeitskorrekturen (Thermokeratoplastik) eingesetzt. In ophthalmology, among other things, the laser photocoagulation in the treatment of glaucoma (transskerale cyclophotocoagulation TSCPC) and refractive error corrections (thermokeratoplasty) is used. Alleiniger Steuerparameter während der TSCPC sind bislang bei vorgewählter Laserleistung die vorab geschätzte Bestrahlungsdauer. Sole control parameters during TSCPC are far with selective laser power, the previously estimated irradiation time. Darüberhinaus kann nicht beurteilt werden ob der Ziliarkörper oder angrenzende Strukturen getroffen werden. Moreover, can not be judged whether the ciliary body or adjacent structures are made. Die Effektivität dieses Eingriffs wird durch die Therapiekontrolle mit dem on line- Thermometrieverfahren deutlich verbessert. The effectiveness of this intervention is significantly improved by treatment with the control on line- Thermometrieverfahren.
