Purpose: In percutaneous renal ablation (PRA), reaching the target accurately is challenging due to target motion and limited real-time visualization of the target, requiring a suitable navigation strategy. In the context of this thesis research, skin markers are used in combination with an the Azurion C-arm system (Philips Healthcare, Best, The...

Summary<br/>Introduction<br/>The increasing use of cardiac catheterisation procedures has raised concerns about occupational radiation exposure and its associated health risks for clinicians. Radiation exposure can lead to deterministic and stochastic effects, including cataract and various cancers. To minimise these risks, the ALARA (As Low As...

Breast cancer is the most prevalent form of cancer among women, leading to 2.3 million new diagnosis and almost 685,000 deaths in 2020. Currently, one of the preferred treatments is breast conserving surgery (BCS), but its success depends on the correct identification of tumor margins during surgery. A promising optical intraoperative margin...

Introduction Sudden cardiac death is one of the major deaths worldwide. Several treatments are available to lower risks of sudden cardiac deaths. Atrial fibrillation is one of the leading causes for sudden cardiac deaths. Atrial fibrillation can be treated with drugs or with procedures or surgeries. Catheter ablation is one of these procedures....

In the Netherlands, 362.000 people suffered from atrial fibrillation in 2019. During a catheter intervention, the tissue that causes atrial fibrillation is destroyed by heat generated by an alternating current exerted from an ablation catheter. Two problems of this treatment are over-ablation of the heart tissue and the non-contingent...

Spinal fusion is a surgical treatment involving stiffening parts of the spinal column to eliminate any relative motion and improve spine stability. A critical part of spinal fusion surgery is the placement of pedicle screws because it is highly complex and can damage the vascular structures and nerves near the vertebrae. To prevent complications...

The growing demand for cardiovascular treatments and the need to control the ever rising health care expenditures require efficient use of expensive resources, such as cardiac catheterization laboratories (cath labs). These in cardiac catheterization specialized operating rooms are labor and capital-intensive. Therefore, a high utilization is...

Background Current neurosurgical visualisation systems, operating microscopes as well as exoscopic systems, display problems that make their performance suboptimal. Operating microscopes severely restrict ergonomics, occasionally leading to pain or injuries. Existing exoscope systems have diverse limitations, therefore not yet being able to...

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...

Maximisation of treatment efficiency in hospitals can lead to significant growth in terms of patient satisfaction, staff productivity and hospital revenue. Scheduling for the operating department is currently done manually, using standard values for duration that vary with procedure type. This implies that no patient characteristics nor...

Atrial fibrillation (AF) is the most common form of arrythmia. Without treatment, the heart rhythm usually becomes permanently disrupted and can lead to various heart related complications as stroke or heart failure. Cardiac phantoms are needed for the development of electrophysiological instruments and for training and education of...

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...

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...

Previous studies show that the smart electrosurgical knife, which adds diffuse reflectance spectroscopy to the traditional electrosurgical knife, is a promising technique for breast-conserving surgery, namely it enables real-time tissue characterization while cutting. More specifically, based on the fat/water-ratio, it enables intraoperative...

Cardiovascular disease is the number one cause of death in the USA and number two in the Netherlands(1, 2). In addition, it is expected that in 2030 40.5% of the population in America will be inflicted with a form of cardiovascular disease(2). The growing volumes and thereby health care costs will put a strain on hospitals and health care...

Neurosurgery is technically challenging because of the inaccessibility and sensitivity of the brain. The risk of complications for the patient is high and simulation-based training is therefore preferred. However, surgical training in cadavers and virtual reality is not satisfactory. A phantom is a model of organs or tissues consisting of tissue...

During use of the smart electrosurgical knife, deterioration of the diffuse reflectance spectroscopy (DRS) signal intensity obstructs proper distinction between tissues. In order to reduce signal loss, this research has focused on the influence of smart electrosurgery on both the morphology and composition of the layer covering the optical fiber...

Transvenous lead extractions (TLEs) are minimally invasive procedures in which pacing or implantable cardioverter defibrillator leads are extracted under guidance of 2D X-ray fluoroscopy. Despite the fact that fluoroscopy is currently the gold standard for TLEs, it has several limitations in terms of visualization of anatomical structures, areas...
