Evaluation of diffusion‐weighted MRI and geometric distortion on a 0.35T MR‐LINAC at multiple gantry angles

Journal of Applied Clinical Medical Physics, 2021
Diffusion‐weighted imaging (DWI) provides a valuable diagnostic tool for tumor evaluation. Yet, it is difficult to acquire daily MRI data sets in the traditional radiotherapy clinical setting due to patient burden and limited resources.

Prehension and perception of size in left visual neglect [PDF]

, 2001
Right hemisphere damaged patients with and without left visual neglect, and age-matched controls had objects of various sizes presented within left or right body hemispace. Subjects were asked to estimate the objects’ sizes or to reach out and grasp them,

Toward Cultural Oncology: The Evolutionary Information Dynamics of Cancer [PDF]

, 2003
'Racial' disparities among cancers, particularly of the breast and prostate, are something of a mystery. For the US, in the face of slavery and its sequelae, centuries of interbreeding have greatly leavened genetic differences between 'Blacks' and ...

Clinical impact of magnetic resonance imaging distortions on gamma knife radiosurgery [PDF]

Journal of Medical Radiation Sciences, 2021
AbstractIntroductionMagnetic resonance imaging (MRI) is the preferred imaging modality for Leksell Gamma Knife® (LGK) stereotactic radiosurgery (SRS) treatment planning (TP) due to superior soft tissue definition compared to computed tomography (CT). However, inherent distortions in MRI can affect treatment accuracy.
