Most techniques provide resolution of the order of 1 mm

Resolution - Smallest feature that may be seen clearly

X-Ray Films 0.1 mm X-ray radiation

Mammography 0.03 X-ray radiation

CT Scan 0.4 X-ray radiation

PET Scan 5-7 Nuclear radiation

MRI 1.0 Radio-frequency

Ultrasound 0.3 Sound waves

Further Information:
Since the discovery of X-rays over 100 years ago with their potential for medical imaging, developments in physics have been vital to the advancement of medicine. MRI, CT, PET and ultrasound scans, and various types of radiotherapy are some of the physics-based devices that help diagnose and treat ailments ranging from broken bones to cancer.

Dr Singhal will explain the science behind medical imaging. The talks are aimed at the general audience and no prior background in physics or biology is assumed. The talks are particularly suitable for secondary school pupils who are encouraged to attend. The presentation is visually attractive and highly informative. Talks are free to attend.

The talks are part of the community education initiative under the Science for All programme
