Field mapping system

Final year B.Tech students- Vamshi Krishnan and Aditya Kalluri have developed a precision field mapping system designed to assess the magnetic field uniformity within our upcoming MRI setup. This system is a high-accuracy, 3-axis translational platform capable of scanning the designated field of view with a positional precision of up to 0.01 mm.

The field mapper operates within the following workspace dimensions:

X-axis: -12.5 cm to +12.5 cm

Y-axis: 0 cm to 25 cm

Z-axis: 0 cm to 50 cm

At each point within this 3D volume, the system measures the magnetic field strength, enabling detailed analysis of field homogeneity. This is a critical step in ensuring optimal image quality and performance in MRI applications, as even minor variations in the magnetic field can significantly impact imaging results.

CSF flow quantification in the Human Brain

Cerebrospinal fluid (CSF) dynamics in the human brain is investigated, with a focus on understanding altered flow patterns in Normal Pressure Hydrocephalus. CSF serves essential physiological functions, including mechanical protection, waste clearance, and the maintenance of biochemical stability.

This work is conducted by M.Tech student Utkarsh Srivastava in collaboration with Citi Neuro Centre, Hyderabad, under the co-supervision of Dr. D. Ravi Varma, Senior Consultant Interventional Neuroradiologist.
