Radiation dermatitis occurs when the exposure dose exceeds a certain level.
Symptoms appear when the delivered dose exceeds the threshold. The rate of incidence increases and the symptoms increase in severity as the exposure dose increases. There is no influence from exposure to doses below the threshold value. Treatment can therefore be completed safely as long as the delivered dose is kept below this threshold.
Do you know about radiation exposure in the workspace at medical sites?
31 physicians with an average of 23 years performing interventional procedures developed tumors of the head and neck. 85% of the tumors were located on the left side of the head. These are serious facts that were presented in a paper
"Providing the best healthcare for patients, ensuring operator safety, and providing reassurance to medical facility administrators." Based on this concept, Canon Medical Systms X-ray angiography systems have been developed with careful consideration of all people concerned.
Over time we have applied several approaches, which have resulted in a variety of X-ray reduction techniques: "AIP" image processing, which significantly reduces quantum noise in images, provides high-quality fluoroscopic images in real time with les lags, and thus helps reduce the need to perform DA, which requires relatively high radiation doses; "DoseRite SpotFluoro", which generates X-rays only in the ROI; "DoseRite DTS", which visualizes the patient incident skin dose distribution with color mapping in realtime during the procedure to control the risk of radiation dermatitis; and many other techniques. All the dose reduction techniques and dose management techniques incorporated in Canon Medical Systms X-ray angiography systems are inclusively referred to as "DoseRite". In order to provide safer healthcare systems for patients, operators, medical facility administrators, and all others concerned, Canon Medical Systms continues to develop techniques for further dose reduction.
Various recording modes are available for high-quality fluoroscopic images acquired with the SNRF. These acquisition techniques can be operated simply by pressing the footswitch. The clinician can choose fluoroscopic acquisition in the same manner as DA acquisition, allowing the patient X-ray dose to be reduced.
Fluoroscopic images acquired after pressing the fluoroscopy start button are recorded. Images can be recorded for up to 90 seconds or 1020 frames. (Dynamic image recording)
Fluoroscopic images acquired in the last 60 seconds (max.) are recorded. Press the F-STORE button after fluoroscopy is completed to save the run as part of the patient file. (Dynamic image recording)
The LIH (last image hold) image acquired in fluoroscopy is recorded. (Still image recording)
