MOVING PARTS IN A NUCLEAR MEDICINE (N-M) IMAGING SYSTEM

A Nuclear Medicine (N-M) imaging system including a gantry having a stationary stator and a rotor rotatably mounted on the stator and including detection units. The rotor is driven by a rotor driving assembly including a linear encoder. The detection units mounted on the rotor include scanning columns having one or more Multi-Pixel Photon Counter (MPC) mounted on one or more extendable arm. The gantry also includes flat cables connecting the controller with gantry components, e.g., the scanning column Multi-Pixel Photon Counters (MPC). The scanning columns are pivotably moveable by a scanning column driver system including a rotary encoder.

X-RAY SPECTROMETER AND METHODS FOR USE
20190257774 · 2019-08-22 ·

A spectrometer includes a crystal analyzer having a radius of curvature that defines a Rowland circle, a sample stage configured to support a sample such that the sample is offset from the Rowland circle, an x-ray source configured to emit unfocused x-rays toward the sample stage, and a position-sensitive detector that is tangent to the Rowland circle. A method performed via a spectrometer includes emitting, via an x-ray source, unfocused x-rays toward a sample that is mounted on a sample stage such that the sample is offset from the Rowland Circle, thereby causing the sample to emit x-rays that impinge on the crystal analyzer or transmit a portion of the unfocused x-rays to impinge on the crystal analyzer; scattering, via the crystal analyzer, the x-rays that impinge on the crystal analyzer; and detecting the scattered x-rays via a position-sensitive detector that is tangent to the Rowland circle.

Radiation CT apparatus
09691166 · 2017-06-27 · ·

A radiation CT apparatus that can gain a clear tomogram without a rotation axis runout and without fail through a single CT scan and a simple operation is provided. When the data on the projection with radiation collected through a CT scan is first reconstructed through an arithmetic operation by a reconstruction arithmetic operation unit 13, temporary coordinates that have been set in advance as the coordinates of the projected rotation axis so as to construct a tomogram along a predetermined sliced surface are used, this tomogram is displayed on the screen for changing the rotation axis coordinates that include the temporary coordinates, and the coordinates of the projected rotation axis are shifted by any amount in any direction through an operation on the screen so that a reconstruction arithmetic operation is again carried out in the reconstruction arithmetic operation unit 13.
