Imaging biological structures with a proton microprobe

Imaging the morphology of the tissue in vivo and producing the correspondent elemental maps, whether in major, minor, or trace concentrations in real-time can be done using a focused beam of accelerated particles. This can be accomplished using different ion beam techniques simultaneously such as Scanning transmission ion microscopy (STIM), secondary electron imaging (SEI), Rutherford backscatt...

Integrating External Sensors into Scanning Vibrometer Measurements

Integration as described here requires the 8.5 version of the PSV software, as new functions are required in the signal processor, for example ReIndex. The 1-D or 3-D PSV vibration measurement data must be available with the geometry, i.e. the geometry is either importe-(for example from an FE model) or it is defined and measured using the PSV software. For this purpose, the software option PSV...

Scanning electron microscopic and electron microprobe X-ray analysis of cortical bone of fluoride-treated rabbits.

Sodium fluoride was administered to rabbits through the intragastric route at the rate of 10 mg/kg every day for a period of 8 months. Cortical bone from the diphyseal region of the femur was studied morphologically with a scanning electron microscope, and significant structural changes in collagen fiber were observed in the fluoride-treated animals as compared to normal bone. Similar bone samp...

Differential phase contrast with a segmented detector in a scanning X-ray microprobe.

Scanning X-ray microprobes are unique tools for the nanoscale investigation of specimens from the life, environmental, materials and other fields of sciences. Typically they utilize absorption and fluorescence as contrast mechanisms. Phase contrast is a complementary technique that can provide strong contrast with reduced radiation dose for weakly absorbing structures in the multi-keV range. In...

Development of a Scanning System for Proton Therapy in Uppsala

A scanned proton beam yields dose distributions that in most cases are superior to other external radiation treatment modalities, and also to passively scattered proton beams. The present paper gives a description of the scanning system that has been developed at the The Svedberg Laboratory (TSL) in Uppsala. The solution with a small polegap of the magnets and a moveable second magnet gives a v...
