    1. Examination of Accuracy and Factors Influencing Optical Coherence Tomography (OCT) Measurements

      (Article in Japanese) Introduction: Optical coherence tomography (OCT) is a new imaging modality with increasing clinical application. In the present study, we examined the accuracy and factors influencing the OCT measurements (luminal diameter, area, and stent strut thickness).Methods: We evaluated several luminal sizes of phantom model by OCT with several situations (frame-rate: 8.2 or 15.6 F/s; pullback-speed: 1.0 or 2.0 mm/s; position of Image Wire: in-center; off-center) and compared them with the actual value and the intravascular ultrasound measurements. We also evaluated the accuracy of the stent strut thickness (5 bare metal stents ...

    2. Factors That Influence Measurements and Accurate Evaluation of Stent Apposition by Optical Coherence Tomography

      Factors That Influence Measurements and Accurate Evaluation of Stent Apposition by Optical Coherence Tomography
      kground: Factors influencing measurements and accurate evaluation of stent apposition by optical coherence tomography (OCT) are not established. Methods and Results: Phantom models of known luminal sizes and lengths were evaluated by OCT under various conditions and measurements were compared with actual values. Stents implanted into phantom models were examined by OCT to validate the measurement point on the stent strut surface for accurate evaluation of stent apposition. Strut thickness was measured at 3 points (midpoint, inner and outer surfaces of the stent shadow). The precision of OCT measurements of lumen diameter and area was satisfactory when the image wire ...
