Latest Patents
One of Takanaka's latest patents involves an X-ray diagnostic apparatus that includes an X-ray generator, a current measurement circuit, a display, and processing circuitry. The X-ray generator features a filament connected to a cathode of an X-ray tube, which emits electrons. A target connected to the anode of the X-ray tube generates X-rays by receiving these electrons. Additionally, a grid is configured to adjust the electric potential gradient around the filament. The current measurement circuit measures the electric current flowing between an electrode of the grid and a common electrode of the filament. The processing circuitry calculates an index related to the lifetime of the filament based on the measurement value of the electric current and displays this index on the display.
Another notable patent is an X-ray diagnosis apparatus that includes judging circuitry to determine whether a voltage should be applied to a grid of the X-ray tube. This apparatus is designed to radiate X-rays, with the judging circuitry assessing the need for voltage application based on radiation conditions. If deemed necessary, the grid controlling circuitry applies the voltage to the grid.
