DE2747310A1 - X-RAY DIAGNOSTIC APPARATUS WITH MEANS FOR PROGRAMMED INPUT OF THE DATA REQUIRED FOR AN X-RAY EXAMINATION - Google Patents

Description

The present invention relates to an X-ray diagnostic apparatus with a keyboard for pre-programmed Input of the data required for an X-ray examination of an object, which can be set using suitable means, and associated with the keyboard, essentially composed of an overview diagram divided into object zones and an overview diagram Large number of the individual object zones highlighting, i.e. the object parts located in these object zones clarifying information blocks existing display means.

Such devices are provided so that the X-ray examinations to be carried out regularly for a large number of required data can be set very quickly, and that the user is freed from further considerations,

In this context, the DT-AS 2 350 141 provides an X-ray diagnostic apparatus became known in which a system with

/ 2

an overview scheme divided into property zones is available where the individual object zones can be selected using a selector switch or a keyboard. Dependent on From the respectively selected object zone, a second system is used to highlight the respective object zone in more detail, that is, the information block showing the object parts located in these object zones is reproduced, with the individual object parts can be selected via another keyboard, and the data programmed for this purpose for setting be released.

The disadvantage of such an embodiment is that two separate display systems are available, and that each system is assigned its own selection means.

The present invention is based on the object of creating an X-ray diagnostic apparatus in which the programmed Entering the data required for an examination is much simpler and therefore more manageable.

According to the invention the object is achieved in that the one Display items assigned to a common system over the keyboard, which is designed as a so-called computer keyboard suitable electrical organs are assigned in such a way that either the overview or one of the individual diagrams trained note blocks can be selected as desired, with the input of a first number assigned to this number Object zone selected with the corresponding individual scheme and then visually recognizable on the system and at the same time for an overview examination of this property zone

Values stored in a suitable data memory are released for setting the corresponding data, and by an input that may have to be made a further number, the values also stored in the data memory for the setting of the one selected in the Object zone located corresponding object part associated data are released.

Further advantages and features of the subject matter according to the invention are more or less based on one in the drawing schematically illustrated embodiment explained in more detail, namely show:

Figure 1, the basic structure of the invention

moderate object,

FIG. 2, an essential detail of the object according to the invention in perspective Depiction.

As can be seen from FIG. 1, there is one in a control panel which is not illustrated in greater detail for the sake of simplicity X-ray apparatus arranged a system 100 for the purpose of clarification the object zones to be examined or the object parts located therein with an overview diagram S and a multiplicity of individual schemes 1-7 is provided, which also have a Keyboard 110 located in the control panel and designed as a computer keyboard can be selected electrically.

In detail, this means that when the key S is actuated on the system 100, the overview diagram (as in position a clarified), becomes visible. On the other hand, if, for example, the key

909818/0042 Λ

or 3 is first actuated, the corresponding individual diagram 2 or 3 (as ^{illustrated in position a 1} or a ¹ ·) is visible, ie the chest area assigned to this number is displayed on the system 100. This means that by pressing a first button either the overview scheme S or one of the individual schemes 1-7 is visible to the user. Simultaneously with the selection of an individual scheme 1-7f, ie when entering the first number 1 to 7, the data required for an overview of the selected object zone are set, with the corresponding number, expanded by a factor of 10, appearing on a display element 120. The setting of the assigned data takes place via a memory I30 for the number entered on the keyboard 110 and a downstream data memory iko programmed according to the object zones and object parts. From the output of this data memory 1 ko , a signal is picked up via a suitable branching means I50, which is compared with a signal supplied by the memory I30 in a comparator I60 in order to obtain an indication of whether the input on the keyboard 110 is indicated The number is programmed or not. The L or 0 signal resulting as a function of this at the output of the comparator 160 then acts on the display element 120 in such a way that a continuous display is given when an L signal is present and an intermittent display is given when a 0 signal is present.

In the present exemplary embodiment, the last-mentioned state would occur if the first number was an 8

909818/0042 / 5

or a 9 would be entered, as there is no object zone programming for this consists.

If the user wants to carry out an examination in the chest area of a patient based on the overview diagram, he first presses the key 2 provided for this purpose, then he receives the corresponding individual diagram 2 on the system 100 provided for the display object parts located, ie if he wants to investigate the lower rib area, he then only needs to enter 3 as the second number, with the number 23 on the display element 120 and the data assigned to this number from the data memory \ ko get to the setting.

In the present exemplary embodiment, a device is described with which all areas of a patient can be examined. If, on the other hand, the object according to the invention is to be used in a special X-ray examination system, e.g. in a skull examination device, it is only necessary to specify an overview scheme for this area and several individual schemes for different zones of this area and to use a correspondingly coordinated data memory 1 ho .

It is also possible to use the existing ones when using special examination methods, e.g. when taking slices Exchange the data storage device for a data storage device tailored to this examination method.

With reference to FIG. 2, the overview diagram S and the individual diagrams 1 used in the invention are illustrated to 7 containing system 100 explained in more detail. This system is in the control panel of the X-ray machine under a cover 200 arranged in such a way that for the user either the overview diagram S or one of the individual diagrams 1 to 7 becomes visible. For this purpose, the overview scheme S and the individual schemes 1 to 7 on a tape 220 at intervals shows that is held with its two ends on a roller 230, 2 ^ 0 such that the one between them Area is taut under the window 210. The two roles 23O, 2 ^ 0 are corresponding to the two possible Direction of rotation driven by one motor 250, 26o each, the other motor to keep the Belt 220 applies a corresponding counter-torque. The position control of the motors 250, 260 or the belt 220 takes place essentially via a potentiometer 270, which is connected to the roller 230.
