X-ray imaging technology provides powerful support for the diagnosis and treatment of diseases, but it is undeniable that radioactive examinations can cause certain radiation damage to the human body. Therefore, for digital X-ray machine manufacturers, in the pursuit of high-quality images at the same time, the control of radiation dose can not be ignored. Digital X-ray machine (DR) is a major classification of medical imaging equipment, and in 2021, China’s digital X-ray machine holdings of about 116,000 units or so.
Domestic digital X-ray machine manufacturers are how to reduce the dose of X-ray radiation?
In fact, in the design and development stage of the machine, engineers are considering this problem. Deep technology, optimize the design, Pulitzer digital X-ray machine manufacturers to bring radiation low dose management solutions for doctors and patients.
I. DAP exposure dose display
In dose safety management, Pulitzer digital X-ray machine manufacturers use DAP radiation dose monitoring system to protect the health of doctors and patients.
DAP is the cumulative dose of radiation and the product value of the irradiated area, indicating the total number of rays irradiating the human body. Since health care workers are exposed to radiation from the secondary rays produced by the main radiation beam as it passes through the patient. Therefore, the radiation dose to health care workers is closely related to the patient’s DAP. With DAP radiation dose monitoring system, the dose intensity of a single exposure can be displayed in real time on the image, making it easy for doctors to grasp the radiation situation and effectively control the dose intake, providing more health care for doctors and patients.
Second, automatic exposure control function
The automatic exposure control (AEC) function can automatically control the X-ray dose according to the thickness, physiological and pathological characteristics of the illuminated body, so that the images taken in different parts and by different patients have the same light sensitivity, solving the problem of inconsistent light sensitivity and generating good image effects. The operating doctor does not need to select parameters, but only needs to finish the exposure according to the preset value after posing the body to complete the film.
The application of this function effectively reduces the problem of repeated shooting caused by improper operation or poor technique of doctors, greatly reduces the X-ray dose received by medical staff and patients, and at the same time, the output quality images guarantee the clinical diagnosis effect.
Removable filter grids
The design of filter grids can filter out scattered rays, but at the same time will also absorb some useful rays resulting in increased dose. The thicker the patient’s lesion, the more stray rays, and the more filter grids are needed. The thinner the torso of a child or the extremities of an adult, the less stray rays are present and the removal of the filter grid will not improve image quality, but will significantly reduce the radiation dose.
Pulitzer digital X-ray machine manufacturers from the actual clinical needs, the use of removable filter grid design, for children or low dose parts of the examination can be pulled out, to bring more intimate care of patients.
Four, fully automatic electric beam limiter
The fully automatic electric beam limiter can quickly select and preset the required field of view according to the shooting site in APR, and automatically adjust or maintain the irradiation field during the shooting process without much human intervention, which not only reduces the radiation dose to the patient, but also greatly reduces the impact of scattered rays on the imaging quality, and through the predefined field of view size with the automatic beam limiter cropping algorithm, the automatically cropped images, effectively improving image quality.
In addition, Bridgelux digital X-ray machine manufacturers use high-quality flat panel detectors and high-performance X-ray generation devices, fully optimize the software operating system and image intelligent acquisition workstation to achieve higher imaging quality with lower radiation dose, and carefully care for the health of patients.
In the future, Bridgelux digital X-ray machine manufacturers will continue to innovate product design to create more high quality, low dose digital X-ray machine products, to escort the health of life!
