“Dose reduction potential of using gold fiducial markers for kilovoltage image-guided radiotherapy” Extract from abstract: This study aimed to evaluate the possibility of reducing the imaging dose for image-guided radiotherapy by using planar kilovoltage orthogonal imaging and [Gold Anchor] fiducial markers (kV-FM). We tested kilovoltage planar images under clinical imaging conditions for the pelvis (75 […]

“A novel gold marker to aid intraoperative localisation during spinal surgery!” Objectives: The aim of this study was to analyse the accuracy, complications and cost effectiveness of a novel gold marker [Gold Anchor] used as a preoperative spinal marker. Technique (extract): As it is injected into the soft tissue rather than bone, its relatively pain […]
“Carbon ion radiotherapy using fiducial markers for prostate cancer in Osaka HIMAK: Treatment planning” Extract from abstract: Purpose: Carbon ion radiotherapy for prostate cancer was performed using two fine needle Gold Anchor (GA) markers for patient position verification in Osaka Heavy Ion Medical Accelerator in Kansai (Osaka HIMAK). The present study examined treatment plans for […]
“Hepatocellular carcinoma effective stereotactic body radiotherapy using Gold Anchor and the Synchrony system: Two case reports and review of literature” Background: Radiotherapy for hepatocellular carcinoma (HCC) is considered to have limited efficacy because of treatment intensity considering that the irradiated area includes the liver, which is highly radiosensitive. In this report, we present two cases […]
“Endoscopic Ultrasound-Guided Fiducial Placement for Stereotactic Body Radiation Therapy in Patients with Pancreatic Cancer” Extract from abstract: Accurate delivery of stereotactic body radiotherapy (SBRT) to pancreatic tumors relies on successful EUS-guided placement of fiducial markers. …A retrospective chart review was performed for all (n = 82) PC patients referred for EUS-guided fiducial placement by a single endosonographer […]
“Proton therapy planning and image-guidance strategies within a randomized controlled trial for high-risk prostate cancer” Extract from abstract: The Danish Prostate Cancer Group is launching the randomized trial, PROstate PROTON Trial 1 (NCT05350475), that compares photons and protons to the prostate and pelvic lymph nodes in treatment of high-risk prostate cancer. The aim of the […]
“Evaluation of computed tomography metal artifact and CyberKnife fiducial recognition for novel size fiducial markers” Purpose: This study aimed to compare fiducial markers used in CyberKnife treatment in terms of metal artifact intensity observed in CT images and fiducial recognition in the CyberKnife system affected by patient body thickness and type of marker. Methods (extract): […]
“Online Correction of Intrafraction Motion during Volumetric Modulated Arc Therapy for Prostate Radiotherapy: A Cohort Study Quantifying the Frequency of Shifts and Analysis of Men at Highest Risk” Methods (extract): 132 prostate cancer patients underwent planning CT and same day placement of 3 Gold Anchor markers. Triggered kV images were acquired every 10 seconds using […]
“Fiducial markers in adjuvant setting for a patient affected by endometrial cancer: a case report” Introduction (extract): Implantation of Fiducial Markers (FMs) in the vaginal cuff of patients receiving radiotherapy (RT) or brachytherapy could help patient daily setup, image guidance and intra-fraction detection of the radiation targets. Clinical case (extract): Case report of a woman […]
“Real-time tumor-tracking radiotherapy with SyncTraX for primary liver tumors requiring isocenter shift” Abstract (extract): The SyncTraX series enables real-time tumor-tracking radiotherapy through the real-time recognition of a fiducial marker using fluoroscopic images. In this system, the isocenter should be located within approximately 5–7.5 cm from the marker, depending on the version, owing to the limited […]
