MO‐PIS‐Exhibit Hall‐01: Imaging: CT Dose Optimization Technologies I

Partners in Solutions is an exciting new program in which AAPM partners with our vendors to present practical “hands‐on” information about the equipment and software systems that we use in our clinics. The imaging topic this year is CT scanner dose optimization capabilities. Note that the sessions are being held in a special purpose room built on the Exhibit Hall Floor, to encourage further interaction with the vendors. Dose Optimization Capabilities of GE Computed Tomography Scanners Presentation Time: 11:15 – 11:45 AM GE Healthcare is dedicated to the delivery of high quality clinical images through the development of technologies, which optimize the application of ionizing radiation. In computed tomography, dose management solutions fall into four categories: 1.Image Reconstruction Algorithms employs projection data and statistical modeling to decrease noise in the reconstructed image – creating an opportunity for mA reduction in the acquisition of diagnostic images. Veo represents true Model Based Iterative Reconstruction (MBiR). Using high‐level algorithms in tandem with advanced computing power, Veo enables lower pixel noise standard deviation and improved spatial resolution within a single image. 2.OptiDose Technologies Advanced Adaptive Image Filters allow for maintenance of spatial resolution while reducing image noise. Examples of adaptive image space filters include Neuro 3‐D filters and Cardiac Noise Reduction Filters. AutomA adjusts mA along the z‐axis and is the CT equivalent of auto exposure control in conventional x‐ray systems. Dynamic Z‐axis Tracking offers an additional opportunity for dose reduction in helical acquisitions while SmartTrack Z‐axis Tracking serves to ensure beam, collimator and detector alignment during tube rotation. SmartmA provides angular mA modulation. ECG Helical Modulation reduces mA during the systolic phase of the heart cycle. SmartBeam optimization uses bowtie beam‐shaping hardware and software to filter off‐axis x‐rays – minimizing dose and reducing x‐ray scatter. 3.Dose Management Tools The DICOM Radiation Dose Structured Report (RDSR) generates a dose report at the conclusion of every examination. Dose Check preemptively notifies CT operators when scan parameters exceed user‐defined dose thresholds. DoseWatch is an information technology application providing vendor‐agnostic dose tracking and analysis for CT (and all other diagnostic x‐ray modalities) 4.Clinical Applications •SnapShot Pulse improves coronary
