Magnetic resonance-guided ultrasound hyperthermia for prostate cancer radiotherapy: an immobilization device embedding the ultrasound applicator

Guillemin PC, Dipasquale G, Uiterwijk JWE et al. | Journal of 3D Printing in Medicine, 6(2) (ePub ahead of print) (2022) Keywords: 3D printing  •  hyperthermia  •  immobilization  •  MRI  •  prostate cancer  •  radiotherapy The aim of this study was to test a 3D-printed immobilization device for future utilization in magnetic resonance-guided focused ultrasound hyperthermia. The research team utilized a surface scanner to 3D-print patient-specific pelvic immobilization devices. The setup reproducibility was measured both on linear accelerator (LINAC) and magnetic resonance. An ultrasound imaging probe was then utilized to acquire reference images and later to acquire images once attached into the embedded holder. The research group tested prepositioning accuracy at LINAC...
