  • Phase
  • 4. The system of claim 1 , wherein the system is configured to check validity of the treatment plan for data entered intra-phase when the patient's scan image data is acquired at a current phase in the treatment plan for the patient. (google.com.au)
  • Dual-Source Dual-Energy CT Portal Venous Phase Abdominal CT Scans in Large Body Habitus Patients: Preliminary Observations on Image Quality and Material Decomposition. (harvard.edu)
  • SCM is employed (for the first time) to image frost growing under ambient conditions, and MRI is used to visualize phase change and to measure local velocity in natural convection in water-saturated porous media. (asme.org)
  • procedures
  • Time Frame: Retrospective expert comparison of images from patient procedures (between control and experimental arms) will occur within 1 to 3 months after the completion of the pilot study and the full study. (clinicaltrials.gov)
  • Catheterization procedures focus on a small portion of the anatomy forming the central region of the image with the periphery providing contextual information. (clinicaltrials.gov)
  • quality
  • It is hypothesized that systematic application of x-ray attenuation will significantly reduce the radiation exposure of the interventional procedure while maintaining image quality, thereby decreasing risk to the patient. (clinicaltrials.gov)
  • Thus, decreasing the image quality in periphery can provide an overall exposure reduction to patients and interventionists without impacting on diagnosis. (clinicaltrials.gov)
  • A method of producing a high-quality scan by digitizing and subtracting the images produced by high- and low-energy x-rays. (harvard.edu)
  • Image Quality on Dual-energy CTPA Virtual Monoenergetic Images: Quantitative and Qualitative Assessment. (harvard.edu)
  • Objective image quality metrics such as modulation transfer function and detective quantum efficiency were determined using this model and show good agreement with published empirical data. (umassmed.edu)
  • A model such as that addressed in this work could allow for improved understanding of the effect of storage phosphor physical properties and CR reader parameters on objective image quality metrics for existing and evolving CR systems. (umassmed.edu)
  • Use of an ultra-low CM volume protocol at 70 kV is feasible in the evaluation of PAD, resulting in good to excellent image quality with mean ED of 1.1 ± 0.5 mSv. (springer.com)
  • Method
  • 1996) Am. J. Orthodontics 110:365-369 describes a method for laser scanning a plaster dental cast to produce a digital image of the cast. (google.com.au)
