Full Form of QAX
What is QAX?
Quantitative Analysis of X-rays (QAX) refers to a computational technique used to extract numerical data from radiographic images, such as bone density measurements, fracture risk assessment, and tumor characterization. In India, QAX is increasingly adopted in radiology departments of major hospitals and diagnostic centres, especially for osteoporosis screening and orthopaedic evaluations. The technique leverages software algorithms to analyse pixel intensity and patterns in X-ray films or digital images, providing objective metrics that supplement visual interpretation. QAX is commonly used in conjunction with DEXA scans for bone health assessment, but it is also applied in chest X-rays for quantifying lung opacity in conditions like tuberculosis or COVID-19. Its non-invasive nature and reliance on existing X-ray equipment make it cost-effective for Indian healthcare settings. For medical students and radiology residents, understanding QAX is becoming relevant for postgraduate exams such as NEET PG and FRCR, where image quantification is increasingly included. QAX is also explored in research on machine learning-based diagnostics, with Indian institutions like AIIMS conducting studies on its accuracy. Despite its potential, standardised protocols and training remain challenges in widespread clinical adoption across India.
