Title: Innovations in Imaging: The Contributions of Johnny W. Van Der Velden
Introduction
Johnny W. Van Der Velden, based in Heerlen, Netherlands, is a notable inventor recognized for his substantial contributions to the field of imaging technology. With a total of three patents to his name, Van Der Velden has focused on enhancing the efficiency and quality of X-ray image intensifier tubes, making significant strides in medical imaging.
Latest Patents
Van Der Velden's latest patents include innovations that optimize the entrance section of X-ray image intensifier tubes. The first patent focuses on improving image quality by addressing optical aberrations and efficiency. This innovation utilizes a separating layer with adapted electrical transverse conduction to mitigate photocathode charging phenomena. Additionally, by deactivating an edge portion of the entrance screen for specific examinations, scattered radiation is reduced. The introduction of a double phosphor layer with distinct X-ray absorption properties further enhances efficiency.
The second patent involves an X-ray image intensifier tube that incorporates a selective filter within its entrance screen. This design introduces an intermediate layer that selectively absorbs photon energy, effectively reducing the speed of photo-electrons and thereby improving imaging results. By implementing a radial variation of absorption in this intermediate layer, Van Der Velden's design can also compensate for vignetting without compromising sensitivity and resolution in the central portion of the tube, ultimately leading to improved resolution at the periphery.
