A dynamic analysis system processes a dynamic image obtained by irradiation of a subject from a radiation irradiation apparatus and by dynamic imaging on dynamics of the subject detected by a detector. The dynamic analysis system includes a hardware processor that performs position correction of the dynamic image by eliminating an effect of displacement of the subject in a direction perpendicular to a detector plane.

By regarding total precision of an X-ray intensity as counting precision due to statistical fluctuation and counting loss and by regarding the counting precision as a product of precision of an uncorrected intensity, which is an intensity before counting loss correction is performed, and a gradient of a corrected intensity with respect to the uncorrected intensity, a counting time calculation unit (13) included in an X-ray fluorescence spectrometer of the present invention calculates a counting time from specified total precision of the X-ray intensity, a given counting loss correction coefficient, and a given corrected intensity for each measurement line (5).

The present disclosure provides systems and methods for create a scanning pencil beam of x-rays and the air cooling of the system. The system has an enclosure with an x-ray beam source disposed therein. An x-ray wheel having or holding an x-ray attenuating ring is disposed proximate to an end of the enclosure and is configured and disposed to rotate the x-ray attenuating ring and form a scanning pencil beam. The system has at least one air inlet and air outlet and at least one air moving device configured and disposed to move air through the air inlet and the air outlet and to air cool the x-ray system.

An X-ray diffraction apparatus and method of processing signals from an X-ray diffraction apparatus are disclosed. By analysing a time delay between first and second pulses, generated by respective first and second detector cells, and by analysing an energy of each of the first pulse and the second pulse, charge sharing events and coincident photon events can be identified.

An introducer assembly for introducing a catheter into a patient, includes a sheath having a distal end and a proximal end with a hollow lumen extending between the distal end and proximal end. The assembly also includes a coupler having a distal end operatively coupled to the proximal end of the sheath, the coupler having an internal passage in fluid communication with the hollow lumen. The assembly further includes a connector having a distal end operatively coupled to the coupler proximate the distal end of the coupler.

A support program is a program for supporting creation of an interpretation report including a medical image obtained by examining a patient and a region of interest to focus on in the medical image. The support program causes a computer to function as: a reading unit that reads a plurality of interpretation reports created by a plurality of examinations on the same part of the same patient; a difference detection unit that sets one of the plurality of interpretation reports as a detection target interpretation report and sets the others as comparison target interpretation reports, compares regions of interest of the detection target interpretation report and the comparison target interpretation reports, and detects a region of interest, which is present in the comparison target interpretation reports but is not present in the detection target interpretation report, as a difference region; and a notification screen distribution unit that, in a case where the difference region is detected, notifies that the difference region has been detected.

A method for converting spectral CT datasets into electron density datasets with applications in the fields of medical image formation or radiation treatment planning. The method comprises a preparation method that fits free parameters of a generalized electron density prediction model based on obtained electron density values such as data on tissue substitutes, and a conversion method using the fitted parameter prediction model and spectrally decomposed CT data as first and second inputs, respectively. The method is particularly useful in dual-energy CT and more specifically in dual layer detector CT systems.

A non-transitory computer-readable storage medium storing a program causing a computer to perform the following, obtaining a radiation moving image in which a chest portion of a subject when the subject breathes is shown; analyzing a dynamic state of the chest portion based on the radiation moving image obtained in the obtaining; and extracting impedance regarding breathing based on an analysis result obtained in the analyzing.
