With a total of 3 patents to his name, Van Stapele continues to push the boundaries of technology in medical imaging.

Latest Patents

One of his latest patents is a volume-selective magnetic resonance imaging method and device. This innovative method involves a 90-degree excitation pulse followed by two 180-degree pulses, which are slice-selective. The magnetic resonance signal is sampled without magnetic field gradients, allowing for the determination of an MRI spectrum through Fourier transformation. In simpler spin systems, J-refocusing is achieved with a specific echo time, while in more complex systems, only one J-coupling is refocused. The method also incorporates either a chemically selective 180-degree pulse or a broadband 90-degree pulse to ensure J-refocusing occurs regardless of the selected echo time.

Another significant patent is a method and device for the volume-selective extraction of magnetic resonance signals. In this invention, an object containing nuclear spins is placed within a steady uniform magnetic field generated by coils. Magnetic resonance signals are produced through RF pulses, and pulse and gradient sequences facilitate magnetization transfer between different types of nuclei. The process is designed to be volume-selective and utilizes a Hartmann-Hahn transfer sequence for enhanced signal processing.
