State-of-the-art calibration very often constructs models motivated by a real-world device.
Recently, artificial neural networks (ANNs) have been proposed as a more universal …

Galvanometric laser scanners can be used for optical tracking. Model-based calibration of
these systems is inaccurate and not adaptable to variations in the system. Therefore, a …

Marking arbitrary three-dimensional (3D) target curves on given objects with curved surface
is required in many industrial fields, such as fabric prepreg placement in composite material …

Purpose Patient immobilization and X-ray-based imaging provide neither a convenient nor a
very accurate way to ensure low repositioning errors or to compensate for motion in cranial …

This work presents a new method for the accurate estimation of soft tissue thickness based
on near infrared (NIR) laser measurements. By using this estimation, our goal is to develop …

Accuracy is essential for optical head-tracking in cranial radiotherapy. Recently, the
exploitation of local patterns of tissue information was proposed to achieve a more robust …

Our research group is currently develo** a new optical head tracking system for
intracranial radiosurgery. The system uses infrared laser light to measure features of the soft …

Highly accurate localization of the human skull is vital in cranial radiotherapy. Marker-less
optical head tracking provides a fast and accurate way to monitor this motion. Recent …

Purpose: Recent research has shown that optical features significantly improve marker‐less
optical head‐tracking for cranial radiotherapy. Simulations, however, showed that these …

A novel markerless near infrared (NIR) laser-based head tracking system was recently
proposed to resolve patient's head motion problem during cranial radiotherapy. Although …
