Computed Tomography, CT, is in many cases the method of choice for finding injuries and diseases in the body. Unfortunately, the patient is exposed to higher harmful radiation dose compared to a traditional X-ray examination.

Along the large increase in frequency of CT examinations during the last years, the awareness of risks caused by the high radiation doses has thus grown.

Today, CT examinations fully account for half the total radiation dose from medical examinations.

According to the Swedish Radiation Safety Authority (SSM), medical examinations make up the largest average radiation source to the population today. Moreover, the radiation has increased by 25 % since 1995, inter alia due to the increased number of CT examinations. Hence, an intense discussion is up in radiology aiming for what measures to take for reducing patient doses at CT examinations.

 

In general, higher radiation dose gives rise to sharper images, which is crucial for finding the correct diagnosis. Unfortunately, the risks for bodily harms rise when the radiation dose is increased.

With our software, SharpView CT, it is possible to post-process the images so that they get sharp even at low doses.

Several studies have shown that the radiation dose can be decreased by 30 to 70 %, depending on which part of the body to be examined. Therewith, the risks for radiation damages for the patients are reduced.
