Abstract

The apparatus has an antenna measuring cylinder (2) fed from a high-frequency voltage source (1). Individual antennas of the measuring cylinder are electronically scanned under the control of a central computer (3), resulting in different imaging modes, such as general views, sectional views, three-dimensional views, and spatial views. The different views are set at a control desk, and are displaced on a flat screen.

Description

Die Erfindung betrifft eine Vorrichtung zur Untersuchung der weiblichen Brust, und besonders der Lokalisation von Tumoren mit hochfrequenz-elektromagnetischen Weilen. Zugrundegelegt ist dabei die durch diese Wellen entstehenden unterschiedlichen Reflexionen an Stoffen oder Körperteilen mit verschiedenen Dielektrizitätskonstanten. Die Größen dieser Dielektrizitätskonstanten geben ein Bild des Körperinneren. Daraus lässt sich dann ein Gesamtbild des Körperinneren ableiten. Die Bestimmung dieser Dielektrizitätskonstanten erfolgt aus den Größen der verschiedenen elektrischen Feldstärken.The invention relates to a device to examine the female breast, and especially the location of tumors with high frequency electromagnetic waves. Based on is the different resulting from these waves Reflections on fabrics or parts of the body with different dielectric constants. The sizes of this permittivity give a picture of the inside of the body. Leaves it then an overall picture of the inside of the body derived. These dielectric constants are determined from the Sizes of different electric field strengths.

Durch die Anwendung der Gesetze der elektrischen Felder, insbesondere auch der Maxwell'schen Gleichungen, ergibt sich nach verschiedenen Umrechnungen die folgende Beziehung (Gl 1) zwischen der eindringenden Feldstärke E0 und der reflektierten Feldstärke Er. ε20 = (Ee + Er)2/(Ee – Er)2 (1) By applying the laws of electric fields, in particular also Maxwell's equations, the following relationship (Eq 1) results between the penetrating field strength E 0 and the reflected field strength E r after various conversions. ε 2 / ε 0 = (E e + E r ) 2 / (E e - E r ) 2 (1)

Aus dieser Beziehung ist zu erkennen, dass mit den messbaren und während des Messvorgangs ablesbaren Größen wie die Eingangsfeldstärke Ee und der reflektierenden Feldstärke Er die Dielektrizitätskonstante des Tumors ε2 ermittelt werden kann.It can be seen from this relationship that the dielectric constant of the tumor ε 2 can be determined using the measurable variables that can be read off during the measurement process, such as the input field strength E e and the reflecting field strength E r .

Es ist eine weitere Aufgabe zu lösen, nämlich wie die weibliche Brust für die verschiedenen Aufnahmearten abgetastet werden kann. Über den Zentral-Computer werden die einzelnen Antennen auf dem Antennen-Meß-Zylinder [2] elektronisch so abgetastet, dass
Übersichtsaufnahmen [4, 5],
Queraufnahmen [4, 5],
3-D, also
räumliche Aufnahmen [4/5] entstehen. Im Falle der Übersichtsaufnahme wird der Antennen-Meßzylinder [2]- wie auf Bild 2 links zu sehen – wie eine Fläche rechtwinklig abgetastet. Bei der Queraufnahme wird senkrecht zur Übersichtsaufnahme – siehe Bild 2 in der 2. Zeile in der Mitte – die Brust mit den einzelnen Antennen des Antennen-Meßzylinders [2] abgetastet. Bei der 3-D, also räumlichen Aufnahme, werden viele einzelne Queraufnahmen- siehe Bild 2 (2. Zeile ganz rechts) nacheinander abgetastet und danach durch den Zentral-Computer [3] ein räumliches Bild ermittelt. In dem Bild 2 sind diese einzelnen Aufnahmearten dargestellt.
There is another problem to be solved, namely how the female breast can be scanned for the different types of exposure. The individual antennas on the antenna measuring cylinder [ 2 electronically scanned so that
Overview recordings [ 4 . 5 ]
Cross shots [ 4 . 5 ]
3-D, so
spatial recordings [ 4 / 5 ] arise. In the case of an overview, the antenna measuring cylinder [ 2 ] - as can be seen in picture 2 on the left - scanned like a surface at right angles. In the transverse image, the chest with the individual antennas of the antenna measuring cylinder is perpendicular to the overview image - see Figure 2 in the 2nd line in the middle [ 2 ] scanned. With 3-D, i.e. spatial recording, many individual transverse recordings - see Figure 2 (2nd line on the far right) are scanned one after the other and then by the central computer [ 3 ] determined a spatial image. Figure 2 shows these individual types of exposure.

In dem unten gezeichneten Bild 3 ist die gesamte Anlage in einer Übersicht dargestellt. Hierbei ist der Antennen-Meßzylinder in zwei Projektionen, nämlich in der xz-und in der x,y-Projektion dargestellt.In the picture below 3 is an overview of the entire system shown. Here the antenna measuring cylinder is in two projections, namely in the xz and shown in the x, y projection.

In diesem Bild 3 ist zu sehen, daß von rechts unten – also von der Hochspannungs- Hochfrequenzversorgung Versorgung [1] die Antennen-Messzylinder [2] sowie die gesamte übrige Einrichtung gespeist wird. Die von den Antennen-Meßzylindern [2] reflektierten Spannungen gelangen zum Zentral-Computer [3] und damit auch zur Bildsignalverarbeitung [4]. Zur Erstellung der verschiedenen Bildvarianten dient die Signalverarbeitungseinheit [4] bzw. das Aufnahmebedienpult [5].In Figure 3 it can be seen that from the bottom right - that is, from the high-voltage high-frequency supply [ 1 ] the antenna measuring cylinder [ 2 ] and the rest of the facility is fed. The antenna measuring cylinders [ 2 ] reflected voltages reach the central computer [ 3 ] and thus also for image signal processing [ 4 ]. The signal processing unit is used to create the different image variants [ 4 ] or the recording control panel [ 5 ].

Die Antennen-Meßzylinder [2] , das Bedienpult [5] sowie der Flachbildschirm [6] sind an einem Stativ [7] angebracht, das in allen Dimensionen verstellbar ist.The antenna measuring cylinder [ 2 ], the control panel [ 5 ] as well as the flat screen [ 6 ] are on a tripod [ 7 ] attached, which is adjustable in all dimensions.
