Since the publication of the modified Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED) criteria for the diagnosis of pulmonary embolism (PE), new clinical and scintigraphic diagnostic algorithms (the McMaster clinical criteria, the PisaPED simplified scintigraphic grading and the Miettinen logistic regression analysis) have been reported(More)
A straightforward and accurate method was developed to verify the delivery of intensity-modulated radiation therapy (IMRT) and to reconstruct the dose in a patient. The method is based on a computational algorithm that linearly describes the physical relationship between beamlets and dose-scoring voxels in a patient and the dose image from an electronic(More)
Our experience in developing a traditional expert system motivated us to develop a practical system that applies analogical reasoning to mechanism design. The new system could use existing solutions (apply analogical reasoning) to synthesize new mechanisms; use more informative knowledge representation so it could reason effectively and more meaningfully;(More)
Objectives: Published local control rates for certain stereotactic body radiotherapy (SBRT) lung cancer treatments have exceeded 97%, but several serious adverse events have been reported. No five-year normal tissue complication probability (NTCP) statistical analysis SBRT results have been published yet for skin. While we expectantly await these(More)
Sir, I congratulate Wetterslev et al. on their recent systematic review on the prediction of fluid responsiveness using transthoracic echocardiography (TTE). The difficulties in drawing adequate conclusions from a method that has no gold standard is apparent and highlights, as the authors write, the need for further high-quality studies. However, I would(More)
