Medical network - on March 9, at present, the general put X ray device has been widely used in clinical imaging diagnosis, direct digital X-ray imaging system (DR) provides doctors with more and more convenient diagnostic tool, also lowers the risk diagnosis and treatment for the patients. With the popularity of DR equipment, DR type on the market more and more, its technology and function also is uneven.
How to choose a qualified DR, avoid misdiagnosis of misdiagnosis and clinical diagnosis and realize fast, accurate and efficient diagnosis and has become a hospital and a radiologist focus when choosing equipment!
A qualified DR must have what function?
1. The clairvoyance
Regular DR, imaging in the diagnosis of limitations on some special position, by only one zhang ping can easily result in missed diagnosis and misdiagnosis, as some nodules image diagnosis, the inside of the recessive fractured ribs, etc., to have the perspective function of DR dynamic inspection, lesion location precise visual conditions confirmed that the can avoid the occurrence of these problems very well.
2. High inventory (9 million pixels) function
High inventory is also called hd dynamic point pills, under the condition of dynamic photograph such as perspective, visual observation of pathological changes, to be found suspected instantaneous point when the lesion site, which could obtain the precise high-definition images used for clinical diagnosis of the lesion site, to maximum extent, reduce the misdiagnosis and the misdiagnosis rate.
3. Perspective + high count function, be short of one cannot
Perspective is in order to found the suspected lesions. But if the machine can not simultaneously millisecond high count, process the high clear image that cannot be achieved the perspective of what you see is what you get. It is because of the millisecond high count (9 million pixels) function, DR can found in cases of suspected lesions rapidly get hd static image, convenient to the doctor for further diagnosis of the disease. Millisecond high counting function greatly improve the accurate diagnosis of DR capacity.
Clinical case analysis: the perspective of high count diagnosis of infantile bronchial foreign body
Bronchial foreign body belongs to the critical patients, multiple in children under 5 years of age, the most under the age of 3, accounts for 60 to 70%. The disease, if not timely diagnosis and surgery can be life threatening. Therefore, timely, accurate diagnosis and treatment is important. Aiming at this situation, doctors use perspective under high inventory check, high diagnostic accuracy.
Children, especially infants and young children, as a result of chewing function and throat defensive reflex function is not perfect, there is no self awareness and prone to bronchial foreign body, its cause suffocation death is one of the main cause of accidental death in children. Timely and accurate diagnosis and effective treatment measures to reduce the complications of infantile bronchial foreign body, reducing child mortality rate is very important. The diagnosis of bronchus foreign body is the most important is the history of foreign body suction acquisition, combined with the clinical symptoms, imaging examination to diagnosis. Among them, the imaging examination can better display the direct signs and indirect signs of bronchial foreign body, to guide clinical treatment is important, what method of opaque X-ray foreign body shows more obvious.
Fluoroscopy infantile bronchial foreign body's advantage is to dynamically observe the mediastinal swing, coupled with high count (9 million pixels) function, which can be one of the most dynamic observation of mediastinal swing sharply, and can be more accurate to breath deep and deep breath at the end of the high count and display mediastinal oscillation, the largest of the further observation of the lungs, but also can leave the objective image data, to prevent medical disputes also has a certain value.
A qualified DR, not only need to be observed under fluoroscopy, and need a point when necessary, for further diagnosis. This requires the equipment with the perspective of some piece of functionality, and some pieces of pixels high (9 million pixels) to achieve accurate and efficient diagnosis. |
