Introduction: Currently, there is no method available for intra-operative evaluation of the completeness (transmurality and continuity) of surgical ablation lesions. This study aimed to investigate the changes in electrogram characteristics and activation patterns caused by different (non)transmural and (dis)continuous ablation lesions in ex...

Molecular imaging aims for the visualisation, characterisation, and quantification of biological processes in humans and other living systems at the molecular and cellular level. For today’s patient care, molecular imaging allows for (early) detection and characterisation of disease, efficient planning and assessment of treatments, and...

Cardiac mapping techniques, in which an electrode-array is placed directly on the surface of the heart, were developed to gain a better insight in the underlying electropathology of cardiac arrhythmias. This procedure is performed in patients undergoing cardiac surgery, but here not all relevant cardiac structures and conduction inquiries can be...

The high frequency of osteoarthritis in those aged above 60 years combined with the observing trend of overpopulation leads to increased healthcare costs. To date, clinical treatments seem to be insufficient to restore cartilage and underlying bone degeneration. Bioprinting fabrication techniques constitute a promising approach to mimic and...

We recently developed a dedicated focusing multi-pinhole collimator for a stationary SPECT system that offers down to 120 m (or 1.7 nL) spatial resolution SPECT images of cryo-cooled tissue samples (EXIRAD-3D). This collimator is suitable for imaging isotopes that are often used in small animal and diagnostic SPECT such as 125I (27 keV),...

Introduction: Autoradiography is an established technique for high-resolution imaging of radiolabelled molecules in biological tissue slices. Unfortunately, creating a 3D image from a set of these 2D images is extremely time-consuming and error-prone. MicroSPECT systems provide such 3D images but have a low resolution. Here we present EXIRAD...

Both cryotherapy and thermal ablation are treatment methods for cervical precancerous lesions in screening programs in resource constrained settings. However, for thermal ablation the World Health Organization stated that there is insufficient data to define a standard treatment protocol. This study used an ex-vivo model to compare the tissue...

Expanded Criteria Donor (ECD) organs are being used more often in clinical setting. The regenerative ability of the organs might be able to restore the organ to full functionality ex vivo. For long term kidney stabilization, optimization and monitoring an organ incubator is preferable. However, it is unclear which available parts would work best...

In vivo data acquisition using fiberoptic diffuse reflectance spectroscopy (DRS) is more complicated and less controlled compared to ex vivo data acquisition. It would be of great benefit if classifiers for in vivo tissue discrimination based on DRS could be trained on data obtained ex vivo. In this study, in vivo and ex vivo DRS measurements...

In the field of bone tissue engineering and regenerative medicine, ex vivo embryonic chick femur culture models have demonstrated their experimental advantages. The work reported in this thesis was dedicated to the development of a framework through a bioreactor approach in combination with the technology of micro-computed tomography (?CT) to...

Background Staphylococcus aureus is a common human and animal opportunistic pathogen. In humans nasal carriage of S. aureus is a risk factor for various infections. Methicillin-resistant S. aureus ST398 is highly prevalent in pigs in Europe and North America. The mechanism of successful pig colonization by MRSA ST398 is poorly understood....
