"In 1970 I realized that there was negligible risk from x-rays but many radiographs had poor image quality so that the risk from a false negative was significant"

John Cameron's quote is describing the use of x-rays in medical imaging. In 1970, he recognized that the danger of radiation direct exposure from x-rays was very little, but the quality of the images produced was often poor. This indicated that there was a significant risk of a false unfavorable outcome, implying that a medical condition might be missed out on. This could have serious repercussions for the client, as a condition that is not identified can go neglected. Cameron's quote highlights the importance of ensuring that medical imaging produces premium images, so that the danger of a false unfavorable outcome is reduced. It likewise acts as a pointer of the significance of using radiation-based imaging techniques properly, to guarantee that the danger of radiation exposure is kept to a minimum.
