D-touch: A Consumer-Grade Tangible Interface Module and Musical Applications

, 2003
We define a class of tangible media applications that can be implemented on consumer-grade personal computers. These applications interpret user manipulation of physical objects in a restricted space and produce unlocalized outputs.

Fiducial Placement for Stereotactic Body Radiation Therapy under Only Endoscopic Ultrasonography Guidance in Pancreatic and Hepatic Malignancy: Practical Feasibility and Safety

Gut and Liver, 2014
Background/AimsStereotactic body radiation therapy (SBRT) for gastrointestinal malignancies requires the placement of fiducials to guide treatment delivery. This study aimed to determine the safety and technical feasibility of endoscopic ultrasonography (

FidMark: A Fiducial Marker Ontology for Semantically Describing Visual Markers

Fiducial markers are visual objects that can be placed in the field of view of an imaging sensor to determine its position and orientation, and subsequently the scale and position of other objects within the same field of view. They are used in a wide variety of applications ranging from medical applications to augmented reality (AR) solutions where ...

Enhanced STag Marker System: Materials and Methods for Flexible Robot Localisation

Machines
Accurate localisation is key for the autonomy of mobile robots. Fiducial localisation utilises relative positions of markers physically deployed across an environment to determine a localisation estimate for a robot.

Dosimetric and Deformation Effects of Image-Guided Interventions during Stereotactic Body Radiation Therapy of the Prostate using an Endorectal Balloon

, 2012
During Stereotactic Body Radiotherapy (SBRT) for the treatment of prostate cancer, an inflatable endorectal balloon (ERB) may be used to reduce motion of the target and reduce the dose to the posterior rectal wall.
