Leiden University Medical Center (LUMC) uses Quest Spectrum in ground breaking long tumor surgery
A team from the cardiothorax surgery department in in the LUMC and the Centre for Human Drug Research removed a long tumor that was detected by using fluorescence. This was the first time in Europe that this technique was applied on long tumor patients.
The fluorescent marker is developed in collaboration with the American company On Target and was previously successfully applied by the LUMC on patients suffering from ovarian cancer. This tumor marker, OTL 38, that is injected preoperatively, will bind to the tumor cells and can be detected using the Quest Spectrum. Using this system the surgeon is able to visualize the tumor together with the possibly infected lymph nodes. Additionally the targeted marker allows him to better identify the tumor margins, this will potentially lead to complete resection of the tumor tissue together with the retention of healthy tissue.

Quest Medical Imaging part of consortium grant for evaluation of new fluorescent tracer
Dr. Vahrmeijer from the Leids Universitair Medisch Centrum (LUMC) has obtained a Consortium Grant to improve visualization tools for rectal cancer. Intraoperatively, tumor tissues are visually indistinguishable from healthy tissues by the naked eye. Therefore, Vahrmeijer and his colleagues have started a collaboration with Surgimab and Quest Medical Imaging to improve the contrast with help of fluorescent imaging. Surgimab delivers a compound that can label rectal cancer cells and Quest Medical Imaging delivers the Quest Spectrum to visualize the compound together with the natural color image. This collaboration can result in new technology that allows more accurate surgery with decreased chance of resurrection of tumor tissue.

Quest Medical Imaging part of 29 mln EU Excel grant EXIST
Quest Medical Imaging BV has been rewarded an EU Excel grant with a total vallue of 29 mln euro’s. The three year program has started on May 1st 2017 this year.
EXIST addresses societal needs in the automotive, agriculture, security, professional broadcast and healthcare markets. These needs will be addressed by improving the performance of advanced image capturing systems at the different levels of an imaging system:
- Image sensors;
- Video processing inside camera systems;
Improved image quality will allow for the extraction of more detailed information and a wider range of applicability such as.
- Professional Broadcast Media, and
- Automotive applications.
New technologies will be developed at the imager process technology level and the imaging and vision system design. Their relevance will be demonstrated in a number of applications.
The developed technologies will enable new vision systems answering societal needs,
To minimize potential complications of open surgery, as a diagnostic and interventional procedure, the current healthcare tendency is to move towards robotic image-guided laparoscopic surgery. However, when spatial perception from direct sight and haptic feedback from direct touch are lacking, identification of critical tissues becomes extremely challenging. This can be tackled by e.g., increasing field-of-view and providing image enhancement and classification of critical tissues.
For example, tumour resection region is particularly challenging for the human eye and it often needs to be evaluated afterwards with high probability to either extensive and damaging resection or reoperation. Therefore, a reliable tool to enhance the contrast of between critical tissues is desirable for improved results of laparoscopic procedures. Exploring optical spectroscopy techniques might offer a roadmap towards such a tool, as all tissue types differ in their spectral finger print. Using advanced and multi-modal laparoscopy, by adding a HD hyperspectral imaging on top of current RGB video and by extending data processing to support advanced decision support, will add enormously to disease outcome and patient wellbeing and cutting costs at the same time.
