Description

The invention relates to X-ray technology, more specifically to X-ray diagnostic apparatus with X-ray image intensifiers.

A X-ray diagnostic apparatus is known, which contains an X-ray radiator, an X-ray image intensifier and an X-ray television system M

A disadvantage of the known apparatus is that it does not allow endoscopic examination of hollow organs.

The closest to the invention to the technical essence is an x-ray diagnostic apparatus comprising an emitter, an X-ray image intensifier, an X-ray television system, the transmission tube of which is optically connected to the output window of the X-ray image intensifier and electrically with the input of the television signal forming unit of the X-ray image, the optical television system transmitting the tube of which is electrically connected to the television signal forming unit th picture 2 and picture monitor. .

The disadvantage of this apparatus is that it cannot be used to study hollow organs, i.e., it does not allow to accurately determine the location of the lesion in the hollow organs.

The purpose of the invention is to improve the accuracy of localization of the lesion in the study of hollow organs.

The goal is achieved by the fact that, in an X-ray diagnostic apparatus containing an emitter, an X-ray image intensifier, an X-ray television system, the transmission tube of which is optically connected to the output window of the X-ray image amplifier And electrically with the input of the X-ray television signal formation unit, the optical television system transmitting the tube of which is electrically connected to the television signal forming unit of the optical image and video monitoring e; device, a television image forming unit of a combined image is inserted, containing a threshold yc royue and two electronic keys, the inputs of which are connected to the outputs of optical and X-ray signal generation units, and the outputs are connected to the input of a video control device, while the input of the threshold device is connected with the output of the X-ray image forming unit, the output with the trigger input. Generators of frame and line scan

, the world of the optical image signal, and the endoscope, the output window of which is optically connected to the transmitting tube of the optical television system, is used as the optical system.

The drawing shows the block diagram of the X-ray diagnostic apparatus.

The device contains a power supply device 1, an X-ray emitter 2, an X-ray image amplifier (URI) 3, a transmitting tube 4 of an X-ray television system, a forming unit 5 of a television signal of an X-ray image, a video monitoring device GVKU), an endoscope 7 with a radiopaque tip 8, transmitting tube 9 of an optical a television system, a television signal generating unit of the composite image 10. In block 10, there are electronic keys 11 and 12, and also a threshold device 13. Television This optical image signal is generated by block 14.

one . ;

X-ray diagnostic apparatus operates as follows.

In the fluoroscopic examination of the lungs, the X-ray feeder 1 operates in the scanning mode. X-ray beam generated by emitter

2 and modulated by the object is. following: visualized by MRI 3 and transmitted by means of transmitting tube 4 and forming unit 5 via closed key 11 to VCC 6. Changing the patient's position relative to the system X-ray emitter - URI the doctor seeks to place the image of the lesion in the VCL screen b. Since the full television signal at the output of the television signal imaging unit of the X-ray image 5 does not have a signal from the endoscope tip, the key 11 is closed, and the key 12 is open due to the absence of a video signal from the transmission tube 9, and the image from the transmission tube 4 passes through the VCC b, i.e. x-ray image. When the endoscope is inserted into the tracheobrnhial system, a signal from the endoscope tip appears in the video signal of the first television system. This signal triggers the threshold device 13. As a result, the generators are started | frame and line scan of a television image forming optical image signal 14. On the Control inputs of the keys 11 and 12, a video signal appears from the transmitting tube 9, which opens the key 11, stopping the transfer of the image from the transmitting tube 4 to the ICS 6, and the key 12 closes, allowing the image from the transmitting tube 9 to pass to the ICS 6. the signal from the output of the frame generator pa: the bells of the block 14 are transmitted to the second input of the horizontal scanning generator of the block 14, thereby permitting the generation; horizontal voltage and after passing the transmission tube 9 of the handpiece into the endoscope 7. Thus, an endoscopic image will be displayed on the screen B1SU 6 near the image of the radiopaque tip of the endoscope. As the endoscope moves within the patient’s bronchial tubes, the image of its arm and the endoscopic image of the bronchi and the end of the optic instrument, as if inserted into the endoscope, are moved on the screen of the ICSU.

. As a result of combining both images in one field of view, respectively, the affected area, the physician compares the state of the bronchi in the zone of normal and affected Hbtx areas, as well as the location of the HakdHe4HHKa endoscope and biopsy instrument, as the end osprey advances.

relation to the (nutribronchial part of the pathological formation, to its peribronchial part and, S cases of the full perigronchial formation), to the point

its closest location to the bronchus, to the peribronchial. normal and pathological structures (blood vessels, lesions) located and invisible through the endoscope. In this case, the endoscope of the endoscope is palpable with peribronchially located formations and the point optimal for biopsy and the introduction of contrast

and medicinal substances.

The invention allows a double assessment of the position of the instrument relative to the area and location of the lesion, which provides a more accurate localization of the lesion and reduces the duration of diagnosis and increases its effectiveness. Reduced study duration

unambiguously determines the reduction of the radiation load on the personnel and patients, as well as the dosage of drugs used in anesthesia.
