Simultaneous ThermoBrachytherapy: Electromagnetic Simulation Methods for Fast and Accurate Adaptive Treatment Planning

The combination of interstitial hyperthermia treatment (IHT) with high dose rate brachytherapy (HDR‐BT) can improve clinical outcomes since it highly enhances the efficiency of cell kill, especially when applied simultaneously. Therefore, we have developed the ThermoBrachy applicators. To effectively apply optimal targeted IHT, treatment...

A sensitivity analysis of acoustic wave propagation through the ankle joint space.

Ultrasound imaging is known to be non-invasive, fast, and cost-effective. However, a drawback is its reflection on bone. Therefore, an alternative acoustic wave propagating technique is being developed that eventually should be able to diagnose osteochondral defects (OCDs) that are now often missed with conventional imaging techniques. A novel...

A novel ultrasound technique for detection of osteochondral defects in the ankle joint: A parametric and feasibility study

(Osteo)chondral defects (OCDs) in the ankle are currently diagnosed with modalities that are not convenient to use in long-term follow-ups. Ultrasound (US) imaging, which is a cost-effective and non-invasive alternative, has limited ability to discriminate OCDs. We aim to develop a new diagnostic technique based on US wave propagation through...

Transmission measurement of the photonic band gap of GaN photonic crystal slabs

A high-contrast-ratio (30 dB) photonic band gap in the near-infrared transmission of hole-type GaN two-dimensional photonic crystals (PhCs) is reported. These crystals are deeply etched in a 650 nm thick GaN layer grown on sapphire. A comparison of the measured spectrum with finite difference time domain simulations gives quantitative agreement...
