1. Method of setting up protocols for vendor-specific IR techniques 2. Image quality is dependent on an optimal balance between patient size, tube voltage and tube current 3. Clinical indication and patient size specific CT protocols for application of different IR technique (routine, low dose lung nodule and CT pulmonary embolism) 4. Appearance of chest pathologies that can be scanned at substantially lower radiation dose levels with IR techniques, 5. Appearance of chest findings that need relatively higher dose even with IR techniques.  

1. Overview of iterative reconstruction (IR) techniques from four major CT vendors (AIDR3D, ADMIRE, ASiR, iDose, IMR, IRIS, SAFIRE, SafeCT, VEO). 2. Protocols for chest CT with above mentioned IR techniques, 3. Effect of IR techniques on lesion detection, characterization and overall image quality of chest CT examination at different radiation doses. 4. Illustration of examples from our institutions for chest CT performed at an array of radiation doses. 5. Illustrate effect of different tube potential (kV) and tube current (mA) on the image quality across multiple CT platforms.
