Near infrared spectroscopy, or NIRS, is a scanning technique that uses light of the near infrared (NIR) spectrum for detection of specific molecules. The method is used in the pharmaceutical, medical, diagnostic, food and agrochemical industry.

Since 1977, the year that the brain tissue transparency to NIR light was discovered, many developments have occurred, in order to make the state-of-the-art NIRS as a non-invasive tissue-illumination technique. The first alteration in the NIRS principle was made in the early 1980s, when instead of illuminating the sample by transmission of light through the sample (transillumination), the technique based on reflectance of light was used.

These developments of NIRS, however, were insufficient to make NIRS an accurate detection method, The research question of this project is "Development of novel methods to improve the accuracy of detection and localization of NIRS"

Advise the spanish government on measures which should be introduced to lower the health care costs.

The document starts with a description of the Health Care system in Spain. Paragraph 2 describes the main decisions recently taken by the Spanish Government to manage and limit the Health Care costs. In Paragraph 3 a comparison is made with the Health Care system of The Netherlands. I chose The Netherlands to compare it with because I live in The Netherlands. Paragraph 4 contains my advice about improvements of the Health Care System in Spain. In paragraph 5 I describe the importance of the Cancer disease for the Health Care in Spain. In Paragraph 6 I propose a technological innovation that could have a positive effect on quality and costs of the health care for this particular disease.

In interventional radiology, long guidewires are used to navigate the human body through blood vessels. During such an intervention, several of these guidewires could be needed. Due to their length - up to three meters - it can be cumbersome to keep them sterile and organized during the intervention. They often fall on the ground and lose sterility. Currently there is no satisfying solution to store the guidewires during an intervention single handedly. A novel device was designed in order to store up to eight sterile guidewires up to three meters long during an intervention without compromising the X-ray image quality and the intervention procedure. The device is disposable and can easily be attached to the operation table using existing modular clamps. Significant performance improvements in terms of storing time and using the device single handedly were achieved without obstructing the work field of the interventionalist.
