Hoppener, Bruce (author)Focal laser ablation is a new, promising method to treat tumors. The current focal laser ablation approach is to insert an optical fiber into the patient using rigid needles. A side effect of this approach is that during the needle insertion, tissue damage occurs. The larger the diameter of the needle, the more tissue damage. If the diameter of...master thesis 2023

Fung-A-Jou, Zola (author), Bloemberg, J. (author), Breedveld, P. (author)Needles are commonly used in medical procedures. However, current needle designs have some disadvantages. Therefore, a new generation of hypodermic needles and microneedle patches drawing inspiration from mechanisms found in nature (i.e. bioinspiration) is being developed. In this systematic review, 80 articles were retrieved from Scopus, Web...journal article 2023

Ha, Xuan Thao (author), Wu, D. (author), Ourak, Mouloud (author), Borghesan, Gianni (author), Menciassi, Arianna (author), Poorten, Emmanuel Vander (author)Optical fiber-based shape sensing is gaining popularity in cardiac catheterization lately. Typically, these procedures are taking place under the guidance of fluoroscopy. However, fluoroscopy has several disadvantages. Thanks to fiber optic shape sensing and Electromagnetic Tracking (EMT), the 3D catheter shape can now be tracked in real-time...journal article 2023

(author), Ourak, Mouloud (author), Borghesan, Gianni (author), Menciassi, Arianna (author), Poorten, Emmanuel Vander (author)Minimally invasive catheter-based interventions normally take place under the guidance of fluoroscopy. However, fluoroscopy is harmful to both patients and clinicians. Moreover, it only offers 2-D shape visualization of flexible devices. To solve the problem of harmful radiation and offer 3-D pose and shape information, recent studies propose...journal article 2023

Sickler, Hanna (author)Prostate cancer is the most frequently diagnosed cancer type among men, and the third deathliest form of cancer. Several treatments are available to treat prostate cancer. Low Dose Rate Brachytherapy (LDR BT) is one of them, which inserts permanent radioactive seeds into the prostate using a needle. The literature review performed prior to this...master thesis 2022

Koopman, Laurence (author)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...master thesis 2021

Bloemberg, Jette (author)Standard treatment methods for prostate cancer often result in side-effects because of damage to the surrounding tissue. Magnetic resonance imaging (MRI) guided focal laser ablation to treat prostate cancer reduces the risk of adverse effects by preserving noncancerous tissue. Prostate cancer diagnosis and focal laser ablation treatment both...master thesis 2021
