Brachytherapy (BT) is an essential component in the treatment of cervical cancer as it allows for locally delivering a high dose to the tumour with minimal trauma to surrounding tissues and organs at risk (OARs). However, in advanced cervical cancer patients commercially available BT applicators are particularly ill-adapted and therefore result...

BACKGROUND: Ovarian cancer is the number eight cause of cancer-related mortality in women around the world and has an incidence of more than 295 000 and mortality of almost 158 000. The most important prognostic factor for the survival of advanced-stage ovarian cancer is the complete resection of all microscopic tumour tissue during...

After surgery, 15% of patients experience problems of excessive scarring, causing disfiguring and impaired function. An incision placed in the wrong direction causes unnecessary skin tension on the wound, pulling the wound edges apart. In order to close the wound, increased collagen disposition is needed. Currently, skin tension lines are used...

In the worlds poorest regions there exists an urgent need for surgical care. Open fractures, one of the Bellwether procedures, are treated in only 42% of the health facilities in low- and middle income countries. Worldwide, external fixation is one of the most important treatment methods for open fractures, providing immobilization to the...

Microcatheters are used for endovascular diagnosis and treatment purposes. Variations of this minimally invasive instrument, accompanied by guidewires, are manipulated through the vasculature towards the target of the intervention. The human vascular anatomy can however present complex pathways towards a target, for example a distal tumor....

Currently between 30% till 50%, some even state up to 70%, of medical and laboratory equipment is reported as out of service, due to small or large technical failures or due to missing knowledge of how to use well-functioning equipment in Low-/ Middle- Income Countries (LMIC). This is not due to the complexity of the required repair, but due to,...

Objective: To develop a steerable neuroendoscopic instrument (SNI) based on user requirements found by several means of user research, and to evaluate this instrument on usability and safety. Only 5% of the potential intraventricular neuroendoscopy (INE) cases are currently treated with endoscopy. For the other 95%, an endoscopic approach is...

Background Inter- and intra patient morphological differences and absence of visual feedback make the placement of pedicle screws technically very demanding. As the spine is surrounded by neurovascular tissue, complications can have severe consequences, including paralysis. Guidance techniques are often very expensive and can overexpose surgeons...

A chin deformity does not rarely accompany dentofacial deformities. A correction of the chin (genioplasty) is sometimes indicated in addition to orthognathic surgery. Computer-assisted surgery allows virtual planning in...

Cardiac cells derived from stem cells exhibit cellular contractions when cultured in vitro. They can be integrated with polymeric platforms consisting of micropillars, which act as anchors and pre-load for engineered heart tissue (EHT). The biomechanical response is often characterized using optical microscopy to track the displacement of pillar...

Introduction. In spinal surgery, the misplacement of spinal screws is a problem that causes (severe) pain, bleedings or even paralysis [2]. Screw misplacements are common as navigating in the spine is difficult due to the small vertebral dimensions and a lack of anatomical landmarks [3] [4]. In order to improve the navigational support of spine...

In spinal surgery, the misplacement of spinal screws is a common problem that causes (severe) pain, bleedings or even paralysis [1] [2] [3]. In order to improve the navigational support of spine surgeons, this research focuses on the development of an optical sensing diffuse reflectance spectroscopy (DRS) orthopaedic drill that identifies bone...

During pathogenesis the microstructure and organization of tissue changes and this is reflected in the scattering behaviour. Optical Coherence Tomography (OCT) provides information about tissue morphology by measuring backscattered light and has the potential to enhance optical images with quantitative optical parameters, without the need to...

Every year, 1.7 million woman are diagnosed with breast cancer worldwide. Breast Conserving Surgery (BCS) – where not the whole breast but only the tumour is dissected – is the most common and preferable treatment for these woman. However, 20 to 55% of the patients’ needs a second surgery because of positive margins. A dissected tumour has a...

Driven by rising health care costs due to factors including advancing technology and an aging population, cost-effectiveness has become an increasingly important aspect of care delivery, with the operating room (OR) being a specific area of interest. By means of a surgical process model (SPM), OR systems can gain an understanding of clinical...

The Excimer Laser Assisted Non-Occlusive Anastomoses (ELANA) technique is used to create anastomoses between major arteries in the brain while avoiding the dangerous temporary occlusion of the cerebral blood ow. This decreases the risk of complica ons due to hypoxia of the brain, but the surgery is long and requires a highly skilled vascular...

To reduce the mortality rate of sepsis, treatment needs to be started as soon as possible. One should however first be sure about the occurrence of sepsis. Currently, the suspicion of sepsis in premature infants is based on non-specific physiological changes. The detection of alterations in the inter-heartbeat interval preceding sepsis can offer...

Introduction: Diarrhoea is currently the second major cause of child mortality, which mostly affects children in developing countries. Dehydration is the major risk involved with diarrhoea, which is therefore the actual cause of death in most cases. Currently there are no cheap and reliable methods for assessing dehydration, while dehydration...
