This early stage of the project was mostly dedicated to understanding the procedures and putting things in place. 1 – Observations in the OR A first very important work was to attend several procedures to observe how surgeons work in

1 – Observations in OR Continued observations in the OR, mostly TTTS procedures. Outside of observations conform to the previous ones, I paid special attention to possible installation of the Field generator for the Aurora EM tracking system. This is
Sacha Noimark, March 2015: Further work on developing new coating strategies for laser generated ultrasound and optimisation of MWCNT coatings
Functionalise MWCNTs for dispersion in aqueous solutions. Used CTAB and extensive sonication – optimised MWCNT at 1 mg/mL. Electrospin CTAB-functionalised MWCNTs/ PEO solutions – optimised and achieved thick mesh. Route for alignment of MWCNTs within fibres – fibre diameter <
Sacha Noimark, May 2015: Exploration of new materials for laser-generated ultrasound
Laser-generated ultrasound study #4: 200 micron fibres: MWCNT + PDMS: 4 x 1 dip MWCNT/xylene, 4 x 1 dip MWCNT/xylene/acetone, 2 x integrated fibre. Test for reproducibility. Test fibres against each others. Determined that the fMWCNT xylene coated fibres show
Ex vivo photoacoustic imaging of the human placenta
May 2015 Image guidance plays a central role in minimally invasive fetal surgery, such as photocoagulation of inter-twin placental anastomosing vessels to treat twin-to-twin transfusion syndrome (TTTS). Fetoscopic guidance provides insufficient sensitivity for imaging the vasculature that lies beneath the fetal
Photoacoustic imaging of the human placenta with ultrasonic tracking for TTTS
February 2015 Image guidance is a central component of minimally invasive fetal surgery for treatment of twin-to-twin transfusion syndrome (TTTS). The gold standard for treatment involves laser photocoagulation of anastamosing vessels on the fetal side of the placenta. In current
An interventional multispectral photoacousic imaging system for guiding minimally invasive surgeries
December 2014 Precise device guidance is important for interventional procedures in many different clinical elds including fetal medicine, regional anesthesia, interventional pain management, and interventional oncology. Whilst ultrasound is widely used in clinical practice for real-time guidance, the image contrast
Gustavo Santos, March 2015
Finalising laser speckle work and submission to MICCAI: – Compute mean intensity in images to characterise laser power – Submit speckle movies as supplementary material – Recompute in vivo data and decide what to include Next project: – Plan for

1 – Actuator Following the results of the experiments in London in december and the characterization and modeling of the actuator, a paper was written and submitted to the IROS 2015 conference. First designs have also been made, together with

1 – Observations in OR We continued the observations in the OR, with mostly TTTS procedures. I also attended a FETO and an MMC (Spina bifida, open procedure). The main outcome was a better understanding of the vatiability of patient
