Improved depth perception with three-dimensional auxiliary display and computer generated three-dimensional panoramic overviews in robot-assisted laparoscopy

In comparison to open surgery, endoscopic surgery offers impaired depth perception and narrower field-of-view. To improve depth perception, the Da Vinci robot offers three-dimensional (3-D) video on the console for the surgeon but not for assistants, although both must collaborate. We improved the shared perception of the whole surgical team by...

In vivo wide-band reflectance spectrometry during thyroid and parathyroid surgery

Distinguishing critical tissues can be challenging in (para-)thyroid surgery. As a first step towards intraoperative image contrast enhancement, we collected and analyzed spectral signatures (350-1830nm) of thyroid, parathyroid and recurrent laryngeal nerve in 10 patients.

Wide Band Reflectance Spectrometry and Hyperspectral Imaging for Intraoperative Tissue Recognition (abstract only)

One of the challenges during surgery is to make a proper distinction between vital tissues, structures and organs, both at the surface of the exposed area and beneath it. Currently, identification of different tissue types relies either on the skills and anatomical knowledge of the surgeon (e.g., nerves, blood vessels, different tissue types),...

Difuse optical reflectance spectrometry in thyroid and parathyroid surgery (abstract only)

INTRODUCTION: In thyroid and parathyroid surgery iatrogenic injury of the parathyroid glands or the recurrent laryngeal nerve (RLN) is a possible complication that needs to be prevented. The visible contrast between thyroid and parathyroid tissue is delicate to observe. The aim of this pilot study was to collect in vivo spectral reflectance...

Innovaties in 3D-beeldtechniek: Driedimensionaal meekijken met de chirurg

Met de intrede van minimaal invasieve chirurgie werd 3D-zicht minder vanzelfsprekend. Daar komt steeds meer verandering in. In de console van de Da Vinci-robot beschikt de chirurg inmiddels over 3D-zicht, maar de operatieassistenten moeten het nog met tweedimensionaal beeld doen. TNO werkt samen met urologen aan beeldtechnologie waarmee de...
