Title:
X-RAY CONTRAST MEDIUM AND X-RAY IMAGE ACQUISITION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/234844
Kind Code:
A1
Abstract:
The present invention relates to a method for obtaining an x-ray CT image of a biological sample, and the like, said method including: a step for contrasting by causing a contrast medium that includes wax, that has a density of 0.95 g/cm3 or less in a state of having permeated a biological sample and hardened, and that has a melting point of 40-80°C, to permeate a biological sample and hardening said contrast medium; a step for melting and resolidifying the hardened contrast medium; and a step for irradiating the resolidified biological sample with x-rays having 4-12 keV of energy and acquiring an x-ray CT image. Moreover, said method is such that the shape of the biological sample is a shape for which the maximum optical path length of x-rays within the biological sample in the step for acquiring the x-ray CT image is 2 mm or less.
