Needle Detection and Localization in Ultrasound Images based on Deep Learning

The technique of ultrasound-guided needle insertion is commonly employed in various clinical fields, including biopsy, anesthesia, brachytherapy, and ablation. However, the visibility of the needle in ultrasound (US) images remains a persistent challenge. To improve the guidance accuracy of needle insertion during interventions, it is crucial to...

Design of a patient-tailored 3D-printed HDR brachytherapy applicator for the treatment of cervical cancer

Brachytherapy is a type of internal radiation therapy that is used to treat cervical cancer. It involves the application of a radioactive source in close proximity to the tumour. This can be done either by directly inserting the source into (or close to) the tumour using interstitial hollow needles, or by loading the source into an intracavitary...

A training phantom for a vesicovaginal fistula repair with the transvaginal approach

Background: In Africa, many women suffer from vesicovaginal fistulas. In this study, a phantom model for a vesicovaginal fistula repair was developed that can be produced and used in Africa, to train medical doctors in the treatment of simple fistulas by the transvaginal approach.<br/>Method of production: The phantom consists out of 3D printed...

Creating a Phantom of the Vaginal Cavity for Gynaecological Brachytherapy

The goal of this study is to create a phantom which can be used to test strategies for sealing the vaginal cavity, so that ultrasound gel can be used to fill the vaginal cavity improve the visibility of the vaginal cavity in MR-images.<br/>Silicone rubber and PolyVinyl Alcohol (PVA) were tested, to check whether their mechanical properties can...

Development of a Novel Needle Guide Tool for Percutaneous Interventions with an Omnidirectional Steerable Needle during Real-Time US-Guidance

Radiofrequency ablation (RFA) is a localized thermalintervention technique with the purpose to destroy small tumours (&lt; 3 cm) byheating the tumour tissue. Due to various challenges with targeting andvisualisation during RFA, the clinical need of steerable needles is present forradiologists. Helwig, B.P. developed a new...

Medical instruments identi cation via a luminescent micro-particle coating as an alternative for existing identi cation methods

Medical Asset Management (MAM), track and tracing of medical instruments throughout a hospital, is very comprehensive and complicated. To implement such a system on individual instrument level, a technique that can create Unique Device Identification (UDI) codes is needed. Current UDI systems, such as RFID and barcode scanning, do not suffice....
