      Optical coherence tomography velocimetry based on decorrelation estimation of phasor pair ratios (DEPPAIR)

      Quantitative velocity estimations in optical coherence tomography requires the estimation of the axial and lateral flow components. Optical coherence tomography measures the depth resolved complex field reflected from a sample. While the axial velocity component can be determined from the Doppler shift or phase shift between a pair of consecutive measurements at the same location, the estimation of the lateral component for in vivo applications is still challenging. One approach to determine lateral velocity is multiple simultaneous measurements at different angles. In another approach the lateral component can be retrieved through repeated measurements at (nearly) the same location by an ...

    2. Optical coherence tomography (OCT) to image active and inactive retinoblastomas as well as retinomas

      Optical coherence tomography (OCT) to image active and inactive retinoblastomas as well as retinomas

      Purpose To illustrate Optical Coherence Tomography (OCT) images of active and inactive retinoblastoma (Rb) tumours. Methods Current observational study included patients diagnosed with retinoblastoma and retinoma who were presented at Amsterdam UMC and Jules‐Gonin Eye Hospital, between November 2010 and October 2017. Patients aged between 0 and 4 years were imaged under general anaesthesia with handheld OCT in supine position. Patients older than 4 years were imaged with the conventional OCT (Heidelberg Engineering, Heidelberg Spectralis, Germany). All patients included were divided into two groups: active and inactive tumours (retinoma and regression patterns). Patients’ medical records and OCT images were ...
