Sonographic-guided percutaneous fiducial marker implantation of hepatic malignancies for Cyberknife radiation therapy: Evaluation of safety and technical efficacy

Journal of Medical Sciences, 2015
Background: CyberKnife radiation therapy has a widely used system in the treatment of extracranial lesions. Implanting gold fiducial markers around a tumor is an important procedure for the planning and aiming of CyberKnife radiation therapy.

Computed tomography for four‐dimensional dose calculation: Effect of detector array length

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Purpose Four‐dimensional computed tomography (4DCT) is susceptible to a geometrical error when respiration changes upon patient shift. 4DCT using 16‐cm detector arrays, not needing the shift, has been shown to improve geometrical accuracy, compared with a conventional 4DCT (4‐cm array), albeit with some Hounsfield unit discrepancies. The 4DCTs

External Auditory Canal Metastasis of Colorectal Adenocarcinoma: A Comprehensive Case Report

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Metastatic colorectal adenocarcinoma with a single‐site metastasis to the external auditory canal is an exceedingly rare phenomenon. A multidisciplinary approach involving collaboration among various medical specialties is essential for optimizing patient care and improving survival outcomes.

Thermal Ablation and Rapid On‐Site Cytology for Lung Nodules—A ‘One‐Stop Shop’ Approach for Small Lesions: Experience in 8 Patients

Journal of Medical Imaging and Radiation Oncology, Volume 70, Issue 3, Page 317-321, April 2026.
ABSTRACT Aim This technical report describes our experience with eight patients with small lung lesions (less than 2 cm) treated by thermal ablation after rapid on‐site cytological confirmation of cancer diagnosis. Materials and Methods Six patients were treated by microwave ablation and two by cryoablation, under local anaesthesia.

Comparative evaluation of 4DCT and 4DCBCT for motion and volume measurement accuracy in a dynamic phantom

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background Effective motion management is essential for accurate treatment planning, target localization and dose delivery in lung stereotactic body radiotherapy (SBRT). Lung tumors typically move 5–30 mm in superior‐inferior (SI) direction. The internal target volume (ITV) may be expanded up to 5 mm for day‐to‐day setup variations.

Commissioning and clinical implementation of an MLC tracking system: An evaluation of AAPM TG‐264 guidelines

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background Precise radiotherapy relies on accurately targeting tumours while minimising exposure to healthy tissue, yet patient and organ motion complicate treatment delivery. To address intra‐fractional motion, multi‐leaf collimator (MLC) tracking systems have recently been adopted, adapting beam shapes in real‐time.

CyberKnife Radiosurgery for Prostate Cancer

Technology in Cancer Research & Treatment, 2010
Treatment of prostate cancer with SBRT is an area of significant controversy for many in the radiation oncology community despite radiobiologic data that strongly suggest the prostate would be an excellent SBRT target. Recently, new data have emerged that show promising outcomes with minimal toxicity for CyberKnife SBRT of prostate cancer.

Intravesical prostatic protrusion as a predictor of acute urinary retention following stereotactic body radiation therapy for localised prostate cancer: a retrospective study

Oncologie
Predictors of acute urinary retention after stereotactic body radiotherapy (SBRT) for localised prostate cancer remain undefined. This study aimed to evaluate the association between intravesical prostatic protrusion (IPP) and its occurrence.

Treatment of circumscribed choroidal hemangioma using CyberKnife: A viable alternative

Indian Journal of Ophthalmology, 2019
Circumscribed choroidal hemangioma is a benign vascular hamartoma without systemic associations. For symptomatic cases, treatment options are photodynamic therapy (PDT), transpupillary thermotherapy (TTT), intravitreal injection of anti-vascular ...
