Meanings of fiducial markers in inglés

Conclusions: The gold fiducial markers demonstrated negligible effect on DWI quality.

Therefore, gating without implanted fiducial markers is a promising clinical direction.

Eleven patients were treated with implanted prostate fiducial markers and online set-up corrections.

Digital fluoroscopy was used to measure respiratory-induced motion of implanted fiducial markers within the prostate.

This can be achieved by tracking one or more fiducial markers implanted inside or near the target, either fluoroscopically or electromagnetically.

Cervical spine lesions are located and tracked relative to skull bony landmarks; lower spinal lesions are tracked relative to fiducial markers.

MR images with virtual fiducial markers can be imported into radiosurgical treatment planning software and used to generate an initial treatment plan.

DICOM-compliant MR images with virtual fiducial markers overlaid onto the image can then be generated for recognition by the treatment planning system.

Purpose: There has been an increase in the use of gold fiducial markers to ensure precise radiotherapy delivery in prostate cancer patients.

The registration accuracy was assessed in Hoffman brain phantom studies collected with known misalignments and transmission studies of a thorax phantom with fiducial markers.

The margin required for set-up errors was found to be 10-15 mm unless implanted fiducial markers are available for treatment guidance.

Set-up margins calculated to encompass 98% of prostate set-up shifts were 11-14 mm with bone off-line set-up and 4-7 mm with online fiducial markers.

Introduction: Fiducial markers act as visible surrogates of tumor position during image-guided radiotherapy.
