While providing important basis for medical diagnosis, the control of radiation dose is crucial for Medical Imaging Equipment.
First of all, the rational selection of equipment is the basis for controlling radiation dose. Different Medical Imaging Equipment produces different radiation doses. For example, the radiation levels of X-ray machines, CT and other equipment vary greatly. For specific examination needs, equipment with relatively low radiation dose should be selected. For example, in some cases, ultrasound and magnetic resonance imaging (MRI) equipment do not produce ionizing radiation and can be given priority for examinations of people or specific parts that are sensitive to radiation.
In terms of equipment parameter settings, technicians should optimize and adjust according to the specific conditions of the patients. For example, for smaller patients or children, the tube current and tube voltage of X-rays can be appropriately reduced to reduce radiation dose. At the same time, the rational selection of scanning range and scanning time can also effectively control radiation dose. Avoid unnecessary large-scale scanning and excessive scanning time, and only accurately image the parts that need to be diagnosed.
The application of protective measures is also an important means of controlling radiation dose. When conducting medical imaging examinations, patients can wear protective equipment, such as lead aprons, lead neck collars, etc., to protect non-examination parts and reduce unnecessary radiation exposure. In addition, the design of the examination room should also meet the radiation protection standards, including the use of protective materials and reasonable layout to reduce the radiation level in the surrounding environment.
For operators, strictly following the operating procedures and quality control standards is the key. Operators should receive professional training and be familiar with the performance and operation methods of the equipment to ensure the correct use of the equipment during the examination and avoid the increase of radiation dose due to improper operation. At the same time, the equipment should be regularly inspected and calibrated to ensure the stability of the equipment performance and the radiation output is within the safe range.
In addition, with the continuous advancement of technology, new radiation dose control technologies are also emerging. For example, automatic exposure control technology can automatically adjust the radiation dose according to the patient's body shape and examination site to achieve personalized radiation dose control. There are also some advanced image reconstruction algorithms that can reduce the radiation dose while ensuring image quality.
In short, controlling the radiation dose of Medical Imaging Equipment requires starting from multiple aspects such as equipment selection, parameter setting, protective measures, operator training, and technological innovation to ensure that while obtaining accurate diagnostic information, the potential harm of radiation to patients and staff is minimized.
