Fig 4 — Transverse RD-CTPA image reconstructed with FBP, iDoseL4, iDoseL6, IMR-BR1, IMR-BR2 and IMR-BR3. Subjective image quality and image noise improved with the application of iDose⁴ and IMR compared with FBP. Simultaneously, blotchy appearance increases moderately with application of iterative reconstruction.
