Tumor track seeding: A new complication of fiducial marker insertion [PDF]

Radiology Case Reports, 2014
In the United States, lung cancer is the leading cause of cancer-related death. Candidates for tumor ablation using CyberKnife® require fiducial placement in or near the target tumor to achieve precision.

Tape-Shaped, Multiscale, and Continuous-Readable Fiducial Marker for Indoor Navigation and Localization Systems [PDF]

Sensors
The present study proposes a fiducial marker for location systems that uses computer vision. The marker employs a set of tape-shaped markers that facilitate their positioning in the environment, allowing continuous reading to cover the entire perimeter ...

MRI-guided fiducial marker implantation as a method of tagging an ultrasound- and non-enhanced CT-invisible liver tumor before thermal ablation. [PDF]

Diagn Interv Radiol, 2022
Some liver tumors are not visible on ultrasound or non-enhanced CT (NECT) which are main modalities used in image-guided ablations. This is a report of MR-guided implantation of fiducial marker to tag a neuroendocrine tumor metastasis in a patient with ...

Patient-specific respiratory motion management using lung tumors vs fiducial markers for real-time tumor-tracking stereotactic body radiotherapy

Physics and Imaging in Radiation Oncology, 2023
Background and purpose: In real-time lung tumor-tracking stereotactic body radiotherapy (SBRT), tracking accuracy is related to radiotherapy efficacy. This study aimed to evaluate the respiratory movement relationship between a lung tumor and a fiducial ...

Statistical evaluation of the effectiveness of dual amplitude-gated stereotactic body radiotherapy using fiducial markers and lung volume

Physics and Imaging in Radiation Oncology, 2022
Background and purpose: The low tracking accuracy of lung stereotactic body radiotherapy (SBRT) risks reduced treatment efficacy. We used four-dimensional computed tomography (4DCT) images to determine the correlation between changes in fiducial marker ...

Impact of Fiducial Marker Placement Before Stereotactic Body Radiation Therapy on Clinical Outcomes in Patients With Pancreatic Cancer

Advances in Radiation Oncology, 2021
Purpose: Localized pancreatic cancer is commonly treated with stereotactic body radiation therapy (SBRT), which often requires the placement of fiducial markers. We compared the clinical outcomes of patients with and without fiducial markers. Methods and

From Codes to Patterns: Designing Interactive Decoration for Tableware [PDF]

, 2013
We explore the idea of making aesthetic decorative patterns that contain multiple visual codes. We chart an iterative collaboration with ceramic designers and a restaurant to refine a recognition technology to work reliably on ceramics, produce a pattern
