Assessing proton plans with three different beam delivery systems versus photon plans for head and neck tumors

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To compare plan quality among photon volumetric modulated arc therapy (VMAT) and intensity‐modulated proton therapy (IMPT) with robustness using three different proton beam delivery systems with various spot size (σ) ranges: cyclotron‐generated proton beams (CPBs) (σ: 2.7–7.0 mm), linear accelerator proton beams (LPBs) (σ: 2.9–5.5 mm),

Isolated and silent spinal neurocysticercosis associated with pseudotumor cerebri

open access: yesIndian Journal of Ophthalmology, 2008
Incidence of spinal neurocysticercosis (NCC) is rare. Isolated spinal NCC is still rarer. We present here a case report where a young lady presented with all the clinical features of pseudotumor cerebri (PTC), where medical treatment for PTC failed and ...

Left hippocampus sparing model for glioblastoma radiotherapy by utilizing knowledge‐based planning and multi‐criteria optimization

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Results of a prospective, randomized controlled trial at our institute demonstrate an association between the dose to the left hippocampus and neurocognitive decline post‐radiotherapy for patients with glioblastoma. To minimize the dose to the left hippocampus, a left hippocampus sparing model was created using RapidPlan (RP) and multi‐

Two periodicity conditions for spinal groups [PDF]

open access: yesarXiv, 2021
A constant spinal group is a subgroup of the automorphism group of a regular rooted tree, generated by a group of rooted automorphisms $A$ and a group of directed automorphisms $B$ whose action on a subtree is equal to the global action. We provide two conditions in terms of certain dynamical systems determined by $A$ and $B$ for constant spinal groups

A procedure for implanting a spinal chamber for longitudinal in vivo imaging of the mouse spinal cord. [PDF]

open access: yes, 2014
Studies in the mammalian neocortex have enabled unprecedented resolution of cortical structure, activity, and response to neurodegenerative insults by repeated, time-lapse in vivo imaging in live rodents.

IROC phantoms accurately detect MLC delivery errors

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose We evaluated the impact of random and whole‐bank multileaf collimator (MLC) delivery errors on dosimetric delivery accuracy in the Imaging and Radiation Oncology Core (IROC) phantom audits, as well as differences in delivery accuracy between the IROC phantom prescription and typical clinical fraction sizes.

The search for novel analgesics: re-examining spinal cord circuits with new tools [PDF]

open access: yes, 2014
In this perspective, we propose the absence of detailed information regarding spinal cord circuits that process sensory information remains a major barrier to advancing analgesia.
