Apparatuses (devices, systems) and methods for shielding (protecting) surroundings around periphery of regions of interest located inside objects (e.g., patients) from radiation emitted by X-ray systems towards the objects. Apparatus includes: at least one radiation shield assembly including a support base connectable to an X-ray system radiation source or detector, and a plurality of radiation shield segments sequentially positioned relative to the support base, thereby forming a contiguous radiopaque screen configured for spanning around the region of interest periphery with a radiopaque screen edge opposing the object. Radiation shield segments are individually, actively controllable to extend or contract to selected lengths with respective free ends in directions away from or towards the support base(s), for locally changing contour of the radiopaque screen edge. Applicable for shielding (protecting) medical personnel, and patients, from exposure to X-ray radiation during medical interventions or/and diagnostics.

Apparatus and methods for detecting massive particles, locating their sources and harvesting their energy
11927705 · 2024-03-12 ·

The invention detects massive particles, which are invisible to contemporary particle detectors employing electro-magnetic sensors. The apparatus contains a mechanical sensor detecting massive particles via their influence on mechanical motion of sensor constituent atoms causing changes in sensor characteristics. The apparatus may include said sensor made of crystal or condensed-matter attached as a bob at the end of a pendulum that starts swinging when massive particles hit it. The star-source emitting massive particles is located by finding a space direction from which the particles arrive and produce the changes in said sensor position and physical characteristics. Energy is harvested by using changes in sensor energetic characteristics including mechanical motion, electromagnetic potential, thermal or other reactions. The invented sensor has directly detected massive particles from the Sun, central region of our Galaxy, and the star Deneb. The average mass-energy of solar massive particles is 3.1.sub.1.sup.+1.210.sup.15 eV and mass-energy density near Earth 0.78 GeV/cm.sup.3.

Elemental analysis of organic samples

A method of imaging analyte elements in an organic sample includes providing the sample as a layer on a substrate and reacting the sample on the substrate to produce one or more volatile products that leave the sample while the one or more elements remain in the sample. A majority of the sample layer by weight is removed from the substrate by the reaction and the remaining sample layer is enriched in the one or more elements which are not spatially disturbed by the reaction. The method including subsequently detecting the one or more elements in the concentrated sample layer using an imaging elemental analyzer.
