Abstract
The present invention is formed from main control comuter, digital image-reducing machine, keyboard, interface circuit, XTV, X-ray unit, high-pressure injector and hand switch, etc.. The DSA main control computer can receive the signal transferred from hand switch by means of interface circuit, then takes out digital image-reducing machine information previously inputted from keyboard, and utilizes the interface circuit to control exposure of X-ray unit, the high-pressure injector is used for injecting contrast agent, and the digital image-reducing machine is used for collecting picture from XTV in designed time, then the computer is used for controlling operation.
Description
The present invention relates to a kind of medicine equipment, intervention diagnosis and therapy field particularly, Digital Subtraction machine (Digital Subtracte Analography---DSA) can cooperate X-ray machine to get involved radiography for the doctor.
DSA can only carry out image acquisition by fixing sample frequency at present, and high pressure injector is by the fixing injection of contrast medium of setting of machine.Cause the inconvenience on the working doctor therefrom.
1, the radiography sample frequency can not be set according to different radiography positions by the doctor, and for quick radiography (as the heart radiography), radiography (as phlebography) can not effectively be distinguished at a slow speed, makes it can not reach diagnostic purpose or waste resource fully.
2, need preceding fast back slow for special radiography, or the fast acquisition mode in preceding slow back, be difficult to flexible grasp, often gather less than required image.
3, high pressure injector injection of contrast medium mode is fixed, and can not be difficult to guarantee the carrying out of all kinds of radiographies by the flexible setting of doctor's requirement.
Patent of the present invention proposes solution at above problem.Its use a kind of brand-new control mode, by the doctor can be according to different radiography positions and pre-defined with select different Exposure modes and sample frequency.Analyse and control corresponding operation by the computing machine bolt.
The objective of the invention is to realize by following technical solution: the present invention is made up of main control computer, Digital Subtraction machine, keyboard, interface circuit, XTV, X-ray machine, high pressure injector and rim brake etc.After the DSA main control computer receives the signal that sends by interface circuit from rim brake, take out the Digital Subtraction machine information of importing from keyboard in advance, by the exposure of interface circuit control X-ray machine, the high pressure injector injection of contrast medium, the Digital Subtraction machine time of appointment from the XTV images acquired, set according to DSA control by the computing machine unification and to carry out work.
The present invention can also make corresponding X-ray machine exposure to various radiography positions, DSA gathers and the requirement of high pressure injector injection of contrast medium, is input to computing machine with specific symbol definition, and computer program will be checked its correctness and store.From computer program, access the corresponding site radiography condition of original setting, after finishing preparation, the beginning radiography, according to preestablishing, by connecing optical circuit control X-ray machine condition and exposure, high-pressure injection injection of contrast medium, DSA images acquired accordingly, when radiography finishes by the computing machine above equipment that resets.Set DSA control according to the position of different radiographies, can both collect suitable image effectively different radiography positions.
Advantages such as the present invention compared with prior art has flexible operation, and control is convenient.
Description of drawings of the present invention is as follows:
Fig. 1 is a circuit structure block scheme of the present invention.
Fig. 2 is a programmed control block diagram of the present invention.
The present invention is described in further detail below in conjunction with description of drawings: as shown in Figure 1, DSA main control computer (1), after receiving the signal that sends by interface circuit (4) from rim brake (8), take out the doctor and describe from the DSA of keyboard (3) input in advance.By interface circuit (4) control X-ray machine (6) exposure, high pressure injector (7) injection of contrast medium.DSA (2) time of appointment from XTV (5) images acquired, set according to DSA control by the computing machine unification and to carry out co-ordination.The doctor makes corresponding X-ray machine exposure, DSA collection and the requirement of high pressure injector injection of contrast medium according to the working experience of oneself to various radiography positions, is input to computing machine with specific symbol definition.Computer program will be checked its correctness and store.When the doctor prepares radiography, from computer program, access the corresponding site radiography condition of original setting, after the doctor finishes preparation, the beginning radiography.Calculating will preestablish according to these, by connecing optical circuit control X-ray machine condition and exposure, high-pressure injection injection of contrast medium, DSA images acquired accordingly, when radiography finishes by the computing machine above equipment that resets.Can set different DSA control according to the position of different radiographies and set, make the doctor can both collect suitable image effectively different radiography positions.
As shown in Figure 2, the present invention represents the different controlling object of DSA with the orderization symbol definition, multiplicity and delay time, such as just like giving a definition:
A---represent X-ray machine to expose in the continuous exposure mode.
KV---represent the kilovoltage of X-ray machine.
MA---represent the mA electric current of X-ray machine.
*---represent the DSA images acquired.
#---represent the high pressure injector injection of contrast medium.
Dn---representative time-delay n second (n is a numeral, and unit is second).
Rm (K)---representative repeats (m represents positive number, and K represents corresponding procedure segment) m time to the K process.
/---represent note
@---represent angiographic procedure to finish.
Require the arterial phase blood flow fast for arteriocerebral angiography, answer the fast speed images acquired, the venous phase blood flow slowly can be with the jogging speed images acquired.The doctor can use following symbol sequential combination:
A/X-ray machine begins exposure.
KV85/85kV exposure voltage
MA20/20mA electric current that exposes
*/gather piece image as frisket.
#/high pressure injector start injection contrast preparation.
D0.1/wait 0.1 second.
R20 (* d0.2)/interval was gathered 20 width of cloth images in 0.2 second, and was used to observe arterial phase.
R5 (d1*)/interval was gathered 5 width of cloth images in 1 second and is used to observe venous phase
@/end radiography.
By writing computer program, make it that the DSA symbol of definition is made corresponding bolt and release and control as Fig. 2.The doctor imports computing machine with computer keyboard with above symbol combination.Computer software programs are preserved the symbol of input.When needs, the doctor presses the radiography rim brake, and the radiography rim brake sends corresponding signal by interface circuit and gives computing machine, and after computer software is received interface message, begin in order bolt and release corresponding D SA control character, and by the corresponding operation of interface control circuit control.
As the urgent protection of machine, this control system as is unclamped the radiography rim brake in angiographic procedure; computing machine receives corresponding signal controlling X-ray machine and stops exposure; the control high pressure injector stops injection of contrast medium, and control DSA stops to gather, and software comes back to waits for the rim brake signal condition.
The doctor can also do suitable adjustment according to different patients' situation.Computer program can allow the doctor that different radiography positions is preestablished.In the time of need making corresponding position radiography, the radiography mode that only need access this position is set and is got final product.Computing machine can also go out X line dosage and the radiography time that patient is subjected to according to doctor's set-up and calculated, for the doctor as a reference.
