[A continuous position marker for whole-body computed tomography (author's transl)]

Area of Science:

• Medical imaging technology
• Radiological instrumentation
• Diagnostic imaging physics

Context:

• Accurate patient positioning is critical in whole-body computed tomography (CT) for diagnostic accuracy and radiation dose optimization.
• Current methods for marking patient position can be imprecise or cumbersome.
• Standardization of reference points in CT imaging is essential for reproducible results.

Purpose:

• To introduce a new continuous position marker designed for whole-body computed tomography.
• To provide a reliable method for marking distances from anatomical points or radiation fields.
• To establish a clear zero level reference in relation to the CT image plane.

Summary:

• The developed marker continuously indicates the patient's position relative to anatomical landmarks, radiation fields, and a defined zero level.
• It accounts for the patient's left side as a reference point.
• This system enhances spatial awareness within the CT imaging environment.

Impact:

• Improved accuracy in patient setup for whole-body CT examinations.
• Potential for reduced rescans due to positioning errors.
• Facilitates more precise radiation therapy planning and delivery.
• Contributes to enhanced reproducibility in multi-center CT studies.
