X-ray and optical technologies are the two central pillars for human imaging and therapy.
The strengths of x-rays are deep tissue penetration, effective cytotoxicity, and the ability to …

Purpose Our purpose was to perform an in vivo validation of ultrasound imaging for
intrafraction motion estimation using the Elekta Clarity Autoscan system during prostate …

Purpose Single‐isocenter linear accelerator (LINAC)‐based stereotactic radiosurgery (SRS)
has become a promising treatment technique for the management of multiple brain …

Historically, several different electronic technologies have been utilized to replace the role of
radiographic films in capturing the images, including the scanning liquid ionization chamber …

Background and purpose To evaluate the impact of treatment planning and delivery factors
on treatment outcome as measured by post-treatment disease progression. Materials and …

Objective Current accepted linac Quality Assurance (QA) guidelines used for Volumetric
Modulated Arc Therapy (VMAT) suggest a mechanical isocentre tolerance level of 1 mm …

Purpose To assess the impact of isocenter shifts due to linac gantry and table rotation during
cranial stereotactic radiosurgery on D98, target volume coverage (TVC), conformity (CI), and …

Abstract Purpose: Any Linac will show geometric imprecisions, including non‐ideal
alignment of the gantry, collimator and couch axes, and gantry sag or wobble. Their angular …

Purpose To evaluate the spatial accuracy of radiation centers (RCs) of Elekta stereotactic
cones while changing the cone sizes during intra-fraction treatment of multiple brain …

A fundamental parameter to evaluate the beam delivery precision and stability on a clinical
linear accelerator (linac) is the focal spot position (FSP) measured relative to the collimator …
