3D Image Reconstruction for Image-guided Fetal Surgery
UCL was recently awarded £10million to develop better tools and imaging techniques that will improve the success of surgery and other therapies on unborn babies in collaboration with KU Leuven, Great Ormond Street Hospital and University College London Hospital.
Photoacoustics imaging, a hybrid imaging modality that delivers low-energy laser pulses to generate acoustic waves in response to a transient heating and monitors the resulting ultrasounds with a transducer, promises to drastically improve the quality of the information collected during the surgery. However, with the translation of photoacoustics in situ and in vivo, it is expected than only a small number of depth-measurements or A-scans will be acquired simultaneously. As such there is a need for a method to reconstruct 3D images from a collection of consecutive A-scans.
This PhD project will develop a system to reconstruct such 3D data. Tracking sensors may be embedded on the photoacoustic probe to guide the reconstruction process but a proper understanding of the physics of acquisition will also be required to extract motion information from the correlation within the consecutive A-scans. Close collaboration with the Photoacoustics Imaging Group based within the department is to be expected.
Candidates with a strong interest in the following areas are encouraged to apply: computer-assisted interventions, medical image analysis and analysis, medical device development, and translational applications of medical image computing.
