Sally L. Collins
Biography
Sally graduated in Medicine from the University of Oxford and specialized in Obstetrics and Gynaecology, training within the Oxford region during which time she completed a PhD in Obstetric Ultrasound which started her journey in AI for medical imaging.
She is highly research active having authored over 150 journal articles, filed three patents and won several international research awards.
She currently leads the placenta accreta service at Birmingham Women's Hospital.
AI Research
Using machine learning techniques her team pioneered the first fully automated method for estimating placental morphology and vascularity from a 3D-PD ultrasound image, the OxNNet Toolkit. She is PI on a Phase 2 grant from the NIHR AI in Health and Care awards. This aims to test the clinical utility of the OxNNet Toolkit to predict adverse pregnancy outcomes from a simple first trimester ultrasound scan. A second study is also underway to investigate how easily it can be embedded into a standard NHS ultrasound department and provide a full healthcare economic analysis. It is hoped that this will form the basis of a multifactorial, early pregnancy screening test for fetal growth restriction and pre-eclampsia.
Using transfer learning her team are now aiming to apply their fully convolutional neural network to assess the volume and vascularity of other organs and tumours.
Placenta Accreta Spectrum
Sally co-authored both national (RCOG) and international (FIGO) guidelines for the classification, diagnosis and management of placenta accreta spectrum, (PAS) and was the lead author on the IS-PAS evidence based guideline for intra-partum management of PAS. She is also working with NHS England to develop a national network for the improved management of PAS. She represents the UK to and is Chair of the International Society for PAS (IS-PAS) and belongs to the European Placenta Group.
Expertscape recently ranked her as one of the top three experts in the world for my work on placenta accreta.
