We describe a method for generating CT images at multiple respiratory phases with a single
spiral CT scan, referred to as respiratory‐correlated spiral CT (RCCT). RCCT relies on a …

PURPOSE: We investigate the characteristics of lung tumor motion measured with
respiration-correlated computed tomography (RCCT) and examine the method's applicability to …

PURPOSE: Failure mode and effects analysis (FMEA) is a widely used tool for prospectively
evaluating safety and reliability. We report our experiences in applying FMEA in the setting …

PURPOSE: To quantify the error-detection effectiveness of commonly used quality control (QC)
measures. METHODS: We analyzed incidents from 2007-2010 logged into a voluntary in-…

Purpose To characterize the effect of a prostate-rectum spacer on dose to rectum during
external beam radiation therapy for prostate cancer and to assess for factors correlated with …

Advances in technology have allowed extremely precise control of radiation dose delivery
and localization within a patient. The ability to confidently delineate target tumor boundaries, …

Purpose Patient‐specific quality assurance ( QA ) for intensity‐modulated radiation therapy
( IMRT ) is a ubiquitous clinical procedure, but conventional methods have often been …

We present new results based on observations carried out with the Rossi X-ray Timing Explorer
during the decay of an outburst of the low-mass X-ray binary (LMXB) and atoll source 4U …

Purpose: Hydrogel injected between the rectum and prostate prior to radiotherapy provides
a possible means of increased dose sparing to the rectum. Here the authors evaluate the …

Incident learning is a key component for maintaining safety and quality in healthcare. Its use
is well established and supported by professional society recommendations, regulations …
