Background: Minimally invasive cancellous bone biopsy is a common medical procedure in which a needle is used to extract a piece of cancellous bone for examination. Unfortunately, this procedure is not always successful, as sometimes the biopsy can slip partially or completely, necessitating a new biopsy. The occurrence of these errors is not...

Matthijssen, Rick (author)
Background:<br/>An endomyocardial biopsy (EMB) is an invasive procedure where biopsy samples are taken from within the heart for diagnosis of different myocardiopathies and or heart transplant rejection monitoring. During EMB procedures, a minimum of five tissue samples are required to be taken from the heart wall for investigation. <br/>Current...

Objective: This work focuses on the feasibility of using Electrical Impedance Spectroscopy (EIS) to differentiate between cancerous and healthy tissues in real-time alongside the GI tract. This is to see whether it is possible to support surgeons when taking biopsies, or to see if it is possible to make biopsies obsolete with EIS. Methods: The...

Introduction: Bone biopsies have great value for the diagnosis of, amongst others, hematologic diseases. Although the bone biopsy procedure is mostly performed minimally invasive with the use of a slender cannula, the patient may still experience discomfort, especially when the procedure has to be repeated due to an unsuccessful biopsy. Areas...

Background: Neurosurgical procedures are complex and require years of training and experience. Traditional training on human cadavers is expensive, requires facilities and planning, and raises ethical concerns. Therefore, the use of anthropomorphic phantoms could be an excellent substitute. The aim of the study was to design and develop a...

Breast cancer is currently the most prevalent type of cancer. The concluding diagnosis can be obtained with an MRI-guided biopsy. However, due to respiratory movement and human error, the procedure can require multiple attempts, resulting in harmful consequences. To reach the target at the first attempt, the precision of the procedure should be...

Introduction: In daily practice, at interventional radiology (IR), percutaneous needle placement (e.g. biopsy and ablation) is generally performed under real time guidance of morphological imaging (US or CT). However, in some cases obtaining representative specimen can be challenging causing repeated biopsies or shift to open procedures. And so...

Background: Colonoscopy is a successful screening method to prevent colorectal cancer (CRC). Biopsies are performed from suspicious tissue spots during the colonoscopic procedure to find cancerous polyps in an early stage of the disease. However, taking multiple biopsies is rather time-consuming and requires many repetitious actions from the...

Urine is commonly used for clinical diagnosis and biomedical research. The discovery of extracellular vesicles (EV) in urine opened a new fast-growing scientific field. In the last decade urinary extracellular vesicles (uEVs) were shown to mirror molecular processes as well as physiological and pathological conditions in kidney, urothelial...

Sentinel lymph node biopsy (SLNB) is a procedure that is used to determine the stage of disease of melanoma patients and determine further treatment. However, the morbidities accompanied with this procedure are not negligible (e.g., wound infection, lymphoedema and seroma). With the goal reduce the incidence of morbidities, this thesis...

Neurosurgical training is performed on human cadavers and simulation models, such as VR platforms, which have several drawbacks. Head phantoms could solve most of the issues related to these trainings. The aim of this study was to design a realistic and CT-compatible head phantom, with a specific focus on endo-nasal skull-base surgery and...

Ultrasound imaging is a widely available and highly portable real-time, ionizing radiation-free imaging modality used as first-line in multiple areas. Conventionally, its use is focused on providing 2D imaging using ultrasound probes. However, with the introduction of matrix probes, the acquisition of 3D scans became possible enabling the...

Suspicion of prostate cancer is based on diagnostic tests such as Prostate-Specific-Antigen (PSA) screening or a Digital-rectal-exam. Prostate needle biopsy can be performed to confirm the diagnosis and determine the stage of the disease. The golden standard in prostate biopsy is the trans-rectal biopsy under ultra-sound guidance (TRUS). TRUS is...

PURPOSE. The purpose of this thesis is to investigate the possibility of implementing a prototype of a steerable needle in a medical procedure. Therefore the two main research questions are: “Can the intended user perform a steering motion with the steerable needle and reach the target area following a straight and curved trajectory?” and “Does...

Background: When a suspicious lesion is detected, a thorough examination is essential for the diagnostics of the lesion. Information about the nature and character of the lesion is crucial for the determination of the disease and an appropriate corresponding treatment plan. Taking a biopsy plays an important role in this examination. A biopsy is...

A biopsy is a type of diagnostic medical test, which consists of extracting sample tissue for examination to determine the presence, cause, or extent of a disease. Most commonly, biopsies are used to investigate cancerous or inflammatory conditions. For context of this design study, breast biopsies were chosen as an area of interest. Rather than...

Background. The majority of the benign and malignant lesions in the breast arise from the ductal epithelium and terminal ductlobular unit. A minimally invasive procedure called ductoscopy is able to visualize these lesions as it inspects the ductal epithelium using a small micro-endoscope. Unfortunately, it is currently challenging to obtain...

Background: Ductoscopy is a minimally invasive procedure, using a sub millimeter fiber optical camera, to explore the mammary ductal epithelium for Pathological Nipple Discharge (serous fluid discharged from the milk duct) and breast cancer, detecting lesions up to eight years before other modalities. Although ductoscopy can revolutionize breast...

Contemporary medical imaging technologies, such as computed tomography or magnetic resonance imaging, play a pivotal role in medical diagnosis, allowing for a relatively fast and non-invasive examination of the human body. In the field of cancer surgery they allow for preoperative detection of tumorous tissue and aid the surgical planning....
