Image-Guided Radiotherapy (IGRT)
As mentioned before, #IGRT is a crucial tool in #radiation_therapy, helping detect and correct setup errors before they impact treatment.
Let’s explore the different types of IGRT 🩻
Set-Up Errors in Radiation therapy: ☢️🔄
Set-up errors in radiotherapy can significantly impact treatment accuracy. Let's explore what they are, A set-up error is a discrepancy between the patient's actual position during treatment and their intended position.
Understanding set-up errors is crucial for ensuring the accuracy and effectiveness of radiotherapy treatments.
By implementing proper quality control measures and utilizing advanced technologies like IGRT,we can minimize the risk of these errors and improve patient outcomes.
To account for set-up errors, we use planning target volume (PTV) margins.
These margins are designed to ensure that the target volume receives the intended dose while minimizing radiation to healthy tissues.
A gross error is a significant set-up error that can lead to underdosing of the target or overdosing of healthy tissues.
These errors can be caused by both random and systematic factors.
