Abstract
Official abstract text for this publication.
A lesion phantom is disclosed, which is a spherical ball having a cavity formed therein for housing contrast agents or medicines, and is enabled for the quantitative evaluation of a medical image in drug development and evaluation. In an embodiment, the cavity of the lesion phantom is coupled to a tapering ring and is configured to be sealed by a silicon plug, in order to ensure that contrast agents or medicines can be fed into the cavity easily and conveniently without causing any problem, such as overflowing, a bubble residue problem, radioactive contamination, etc. Moreover, by the arrangement of a retractable fixing bar, the positioning of the lesion phantom can be adjusted flexibly at will, and additionally by the tapering of the tapering ring, the lesion phantom can be prevented from being damaged by any extreme, sudden, unjust, or improper force exerted, and thus the lifespan of the lesion phantom can be prolonged.
First claim
Opening claim text (preview).
What is claimed is: 1. A lesion phantom, comprising: a cavity, formed with an opening; a tapering ring, configured with a first ring and a second ring in a manner that the first ring is formed with a diameter larger than that of the second ring while allowing the first ring to be arranged in communication with the opening of the cavity; a screw tube, formed with an external thread at its outer surface, and having an end thereof to be arranged in communication with the second r…
