How does suspending DR equipment reduce radiation dose?


X-ray imaging technology provides strong support for the diagnosis and treatment of diseases, but it cannot be denied that radiation examinations can cause certain radiation damage to the human body. Therefore, for X-ray machine manufacturers, while pursuing high-quality imaging, radiation dose control cannot be ignored.

Digital X-ray imaging (DR) is a major category of medical imaging equipment, with a total of approximately 116000 DR devices in China in 2021. How does the current medical DR equipment reduce radiation dose?

In fact, engineers are already considering this issue during the design and development stages of machines. Deeply cultivating technology, optimizing design, and providing low dose radiation management solutions for doctors and patients with Pride’s multifunctional dynamic DR.

1、 DAP exposure dose display

In terms of dose safety management, Pulide DR equipment uses a DAP radiation dose monitoring system to ensure the health of doctors and patients.

DAP refers to the product of the cumulative dose of radiation and the area of exposure, representing the total number of rays irradiated on the human body. Due to the radiation exposure received by medical staff coming from the secondary radiation generated when the main beam passes through the patient. Therefore, the radiation dose received by medical staff is closely related to the patient’s DAP. Paired with the DAP radiation dose monitoring system, it can display the dose intensity of a single exposure in real-time on the image, making it easier for doctors to grasp the radiation situation, effectively control dose intake, and provide more health care for doctors and patients.

2、 Automatic exposure control function

The Automatic Exposure Control (AEC) function can automatically control the X-ray dose based on the thickness, physiological and pathological characteristics of the subject, so that images taken from different parts and patients have the same sensitivity, solving the problem of inconsistent sensitivity and generating good image effects. The operating doctor does not need to select parameters, just place the position and expose according to the preset value to complete the photography.

The application of this function effectively reduces the problem of repeated shooting caused by improper operation or low technical skills of doctors, greatly reducing the X-ray dose received by medical staff and patients. At the same time, the high-quality images output also ensure the clinical diagnostic effect.

3、 Removable filter grid

Designing a filter grid can filter out scattered rays, but it can also absorb some useful rays, leading to an increase in dose. The thicker the lesion site of the patient, the more scattered rays there are, and the more filtering grids are needed. However, in thinner areas such as the trunk of children or limbs of adults, there are fewer scattered rays. Removing the filter will not improve the image quality, but it can significantly reduce the radiation dose.

Based on clinical needs, the Pride multifunctional dynamic tablet DR adopts a removable filter grid design, which can be pulled out for children or low-dose examinations, providing more caring care for doctors and patients.

4、 Fully automatic electric beam limiter

By using a fully automatic electric beam limiter, the desired field of view can be quickly selected and preset in APR based on the shooting location. During the shooting process, the irradiation field can be automatically adjusted or maintained without excessive human intervention. This not only reduces the patient’s radiation dose, but also greatly reduces the impact of scattered rays on imaging quality. By combining the predicted field of view size with the automatic beam limiter cropping algorithm, the automatically cropped image can be obtained, effectively improving image quality.

In addition, Perlove Multi functional Dynamic DR adopts high-quality flat panel detectors and efficient X-ray generation devices, comprehensively optimizing software operating systems and intelligent image acquisition workstations to achieve higher imaging quality with lower radiation doses, and carefully caring for the health of doctors and patients. In the future, Perlove Medical will continue to innovate product design and create more high-quality, low-dose dynamic DR products, safeguarding life and health!
