A system configured to detect defects in a first oxygen sensor is disclosed. The system is configured to detect defects in a first oxygen sensor. The system includes an X-ray imaging device configured to capture a production X-ray image of the first oxygen sensor and an electronic processor configured to use a trained oxygen sensor defect detection model to identify a defect of the first oxygen sensor by producing a pseudo X-ray image by simulating a projection of a fan beam through CT data of a second oxygen sensor.

Proposed is a non-destructive osteochondral graft quality analysis method using a Micro-CT assay, rather than using an existing biochemical assay involving destructive pretreatment of osteochondral tissue samples. Since the GAG content of the osteochondral graft can be measured by the non-destructive method through the Micro-CT assay, the quality analysis of the osteochondral graft provided by a donor can be easily performed, and the therapeutic effect of the osteochondral transplantation can be improved by enabling the use of a graft with a GAG content of 70% or more.
