In modern medical diagnostics, imaging technologies such as dynamic DR (Digital Radiography) and CT (Computed Tomography) play crucial roles. These technologies provide doctors with intuitive, clear images of the body, which aid in the accurate diagnosis of diseases. However, radiation dose has always been a focal point of concern due to its direct impact on the health risks of both patients and healthcare professionals.
Dynamic DR, an imaging technology that has rapidly developed in recent years, offers both dynamic and static modes. This means that, in addition to performing standard X-ray imaging like traditional static DR, it can also capture real-time dynamics of the imaged area using high frame rate and multi-angle acquisition technology, synthesizing hundreds of images taken over a short period into a dynamic video.
At this point, one might wonder: with hundreds of images captured in a single scan, does dynamic DR result in a high radiation dose, and how does it compare to CT?
In fact, the radiation dose of dynamic DR is not considered high because it uses low-dose continuous imaging technology. For example, the total radiation dose of a single imaging session on a certain brand of dynamic DR is 1.66 mGry, about 0.23 mSv, which is equivalent to a low-dose chest CT and is below the international standard (International Atomic Energy Agency, IAEA) recommended limit of 1.9 mGy for chest PA and lateral views.
Nowadays, DR equipment offers more intuitive monitoring of radiation dose, thanks to the development and application of DAP (Dose Area Product) monitoring systems. For example, Perlove Medical’s dynamic DR systems are generally equipped with DAP monitoring systems, which can display the dose intensity of each exposure in real time. Doctors can use the data displayed by the DAP to effectively control radiation exposure and prevent over-radiation, thereby protecting both patients and medical staff from unnecessary radiation harm.
With the continuous advancement of science and technology, dynamic DR is expected to have even greater potential for future development and wider application in various fields, such as pediatrics, orthopedics, and pulmonology, providing high-quality medical services to more patients.
