Combining Smart Surgical Knife with Augmented Reality

Posted by Erasmus MC/TU Delft 115 days ago

We are looking for two self-motivated postdocs with a strong interest in working in a flagship multidisciplinary project between Erasmus MC and TU Delft on the topic of smart surgery, supported by the Convergence initiative. In this project, we have two main goals. The first is on the topic of Augmented Reality (AR) for surgery.

In surgical procedures, tissue deep inside organs is not visible to the surgeon. However, the position of such tissue may be required, e.g. for effective planning of place to cut. Modern Augmented Reality technology permits the integration of a virtual model with the real world, and thus could potentially be used to visualize internal structures (e.g. from pre-operative imaging) on the patient. The purpose of this project is to implement and assess such an AR approach for a surgical application. Focus of the project is on the accurate alignment of the virtual (pre-operative) model and the patient, and adequate visualization of the virtual model. Additionally, the project intends to integrate the smart knife output in the field-of-view of the surgeon. The second topic is on the use of a smart electrosurgical knife.

Completely excised tumours provide the best survival chances and the best quality of life. Incomplete tumour resections can be prevented by providing real-time tissue feedback during surgery. Tissue properties can be obtained using spectral tissue sensing techniques with optical with fibers integrated into an electrosurgical knife. Since the feedback is directly integrated in the electrosurgical knife the surgeon is able to assess tumour margin real time during the surgical procedure. Challenges within the project are to define the user interaction such that the knife fits seamlessly into the surgical workflow, and to improve the sensing depth for early detection of the approach of critical structures.

Qualification and skills

Postdoc position 1 TU Delft

  • PhD degree in a relevant engineering discipline, such as Computer Science or Biomedical Imaging
  • Experience with augmented reality is required, experience with computer vision and image registration approaches is an advantage
  • Programming experience and be able to work in a multi-disciplinary team
  • Affinity with experimental work is required

Postdoc position 2 Erasmus MC

  • PhD degree in a relevant engineering discipline, such as Mechanical/ Biomedical/ Electrical Engineering,  Medical Physics or Biomedical Imaging, preferable with experience in medical optics
  • Programming experience and be able to work in a multi-disciplinary team
  • Affinity with experimental work is required

Expectations 

The postdocs should have a deep interest in the convergence of health sciences, physical sciences, and engineering to foster individual health and keep the healthcare system sustainable. They will work closely with the supervisors, Principal investigators and Collaborating investigators of the project to conduct high calibre research. They are also encouraged to initiate and lead collaborative work with other postdocs within the Convergence for health(care) initiative. Salary will be commensurate with qualification and experience.
