Abstract: A first acquisition unit acquires the current position of a carriage unit as information regarding the travel environment of the carriage unit. A second acquisition unit acquires a first upper limit value of the travel speed as appropriate travel conditions of the carriage unit corresponding to the current position acquired by the first acquisition unit. A third acquisition unit acquires a first measurement value of the travel speed as information regarding the travel state of the carriage unit. A travel state correction controller performs travel state correction control to make a correction to a travel state satisfying the appropriate travel conditions in a case where the travel state acquired by the third acquisition unit deviates from the appropriate travel conditions acquired by the second acquisition unit. That is, the travel state correction controller reduces the travel speed of the carriage unit in a case where the first measurement value exceeds the first upper limit value.

A processing system generates a pre-shot image of the subject using low energy X-ray intensity from the X-ray source and determines a plurality of acquisition parameters for a main scan of the subject based on the pre-shot image.

An X-ray dosage level of the subject is then applied using the X-ray source based on the number of time frames and to generate the image of the subject based on the detected X-ray energy at the X-ray detector for the applied X-ray dosage level.

Abstract: An in vitro method for detecting presence of cancer includes obtaining a single hair sample. An x-ray beam is emitted from a source towards the hair sample. A small angle X-ray scattering (SAXS) intensity profile is generated after the x-ray beam hits the hair sample. The SAXS profile is received on a detector to obtain SAXS data, which is desmeared and Kratky Analysis is performed. A relative estimation of peak area under 1.38 nm?1 to 0.89 nm?1 from keratin and lipid content in the hair sample is performed to obtain R and is corrected by dividing by D, thickness of the hair. R? is computed using formula: 10×R2/(D?R). The value of R? is compared with clinically validated samples. If R? value is below 0.7, it indicates the presence of cancer and if it is above 0.8, it indicates absence of cancer.
