notes: label: Description
content: John Wild and John Reid believed ultrasound could be used to image living human tissue and distinguish between different types of tissue, including cancer. Many contemporaries working on ultrasound were focused on mapping the body or imaging the brain. Some doubted the usefulness of blurry ultrasound images in specific and early diagnostics. Wild and Reid were interested in using ultrasound in diagnostics, particularly cancer diagnostics. Wild and Reid knew the lower intestinal tract, prostate, ovaries, and cervix uteri were able to be imaged with a trans-rectal or trans-vaginal endoscope. Their earlier work with breast, brain, and surface imaging aided their work to create a smaller transducer that could be used internally. The closer the transducer to the tissue, the finer the detail on the ultrasonic image. The first theoretical schematic drawing of an endo-echoscope, or ultrasonic endoscope, was drawn by Wild and Reid in 1953. In 1954 Reid and Wild claimed they had successfully created technology to detect minor irregularities in tissue, which would hold value in detecting cancer.
