DR Introduction
DR is the English abbreviation for Direct Digital Radiography, which consists of an electronic cassette, a scanning controller, a system controller, an image monitor, etc. It is a direct conversion of X-ray photons into digital images through the electronic cassette, which is a kind of direct digital radiography in a broad sense. The narrow sense of the direct digital photography that is DDR (DirectDigit Radiography), usually refers to the use of flat panel detector image direct conversion technology of digital radiography, is the true sense of the direct digital radiography system.
DR and CR's **** the same point is the X-ray image information into digital image information, its exposure tolerance relative to the ordinary sensor screen - film system reflects certain advantages: CR and DR due to the use of digital technology, a wide dynamic range, both have a wide exposure tolerance, thus allowing technical errors in the photo, even in some exposure conditions difficult to master the part, but also be able to get a CR and DR can perform various image post-processing according to clinical needs, such as various image filters, window width and window position adjustment, zoom roaming, image stitching, and distance, area, density measurement, etc., which provide technical support for the observation of details, before-and-after comparisons, and quantitative analyses in diagnostic imaging.
Introduction of Universal Innova2000 Flat Panel All-Digital Subtractive X-ray Machine
Innova2000 uses the first cardiac digitized flat panel, indeterminate silicon detector in the human industry, which provides a fully digital image chain. By converting the X-ray into a digital signal at the point of acquisition. The digitized detector captures information with minimal loss throughout the entire process of a typical exposure. It also removes artifacts and distortions created by the conventional image chain.Innova2000 is compatible with any DICOM (unified information standard for medical imaging) and connects seamlessly with any DICOM network picture.
In addition, the Innova2000 has a dynamic range that is 10 times greater than conventional devices, enabling cardiologists to see hard-to-see blood vessels, guidewires, catheters, and stents, in addition to its digital technology, which allows cardiologists to see blood vessels with exceptional clarity. Cardiologists can use the Innova2000 to more easily visualize and treat blockages in coronary arteries during interventional procedures.
Since January 2002, Innova has performed nearly 1.4 million diagnostic interventions in cardiac catheterization laboratories worldwide. Jacques Cargé, France. Jacques Cartier, cardiologist of the French Society of Cardiology, and Marie-Claude Morris, founder of the Cardiovascular Society of Paris-Sud. Dr. Marie Claude Morice, founder of the Cardiovascular Society of Paris-Sud, said, "GE's Innova2000 has made the procedure faster, requiring significantly less exposure and allowing us to see better detail. The result is that better images are produced and the patient receives better care."
George Chen, president of GE Medical Systems China, said, "With GE's latest technology crystalline digital detector, which requires no film and no image intensifier, the Innova2000 will revolutionize X-rays over the next 3-5 years and will increase cardiologists' diagnostic and interventional treatment with confidence."
Exercise Plate System
The exercise plate system is the primary modality for doing ECG load tests. ECG load test is to increase the load of the heart through exercise or other methods (such as drugs, etc.) to increase myocardial oxygen consumption, when the load reaches a certain amount, the myocardial blood supply of patients with coronary stenosis can not be increased accordingly to induce myocardial ischemia, and through the results of the electrocardiogram examination shows, so as to assist in the diagnosis of coronary heart disease, myocardial ischemia.
Flat-panel exercise is a graded exercise in which the amount of exercise increases step by step from small to large, and the duration of each level of exercise varies according to the program until the end point of the exercise is reached.
The changes in the electrocardiogram of the plate exercise test are mainly the changes in the ST segment, and its detection rate is related to the leads used, and the commonly used leads are:
(1) Conventional twelve-lead leads can obtain more complete information, and the detection rate of myocardial ischemia is higher.
(2) 5-lead monitoring method Only a few leads, labeled two, avf, V3-V6, are used, mainly to detect myocardial ischemia in the lower wall and anterior wall.
Indications for exercise plate:
(1) As an auxiliary diagnostic test to clarify coronary heart disease.
(2) For those who have been diagnosed with coronary artery disease, the severity and prognosis of the disease can be assessed, and high-risk patients can be screened for interventional therapy.
(3) Platelet exercise testing of patients with myocardial infarction before discharge from the hospital can be used for prognostic diagnosis.
(4) Plate motion test can be used as an objective indicator for judging the efficacy of various treatments for coronary heart disease.
(5) It can be used as an evaluation standard of heart function and as a basis for objectively arranging the labor force of patients with heart disease and physical therapy exercise program for patients with heart disease.
In addition, the flat plate exercise testing system makes the examinee's exercise process and the amount of exercise load are subject to human control, and the repeatability is good, so it has been widely used by domestic and foreign medical institutions. The maximum oxygen-consuming capacity achieved in the exercise plate test is high, and the expected maximum heart rate is easily reached. In addition, the monitoring of cardiopulmonary function during the plate exercise test is more objective to reflect the cardiopulmonary reserve capacity.
Because of the diversity and complexity of electrocardiographic information, it is no longer possible for the simple surface electrocardiogram to completely and accurately reflect the pathophysiologic changes in each part of the myocardium. Further research on the correlation between exercise testing and coronary artery disease is essential.
