notes: label: Description
content: This is a trans-rectal endoscope for use in ultrasound imaging of the prostate. This is the forth prototype instrument for use in imaging the bowel created by John J. Wild and John Reid. This instrument was hydraulically powered as a response to how hot the electric motors on previous instruments became. Water powered instruments did not become as hot during prolonged used. The power source connected to the sound head is run through a flexible cable contained in the hollow drive shaft. The sound head produces a 90-degree sweep of sound waves which are produced through a slot on the domed end.
label: Description
content: For use, the bowel is inflated with air to ensure room for the sound head. A condom is put on the domed end of the endoscope and inserted into the patient’s rectum. The sound head is filled with water after the device has been inserted into the rectum and it begins to rotate in the 90-degree sweep to produce ultrasound images. It is unclear whether this object was ever used clinically.
label: Description
content: John Wild and John Reid constructed a multi-purpose clinical display unit in 1951 to be used with multiple short range and hand-held instruments. The display unit, not collected here, was comprised of a power source, oscilloscope, amplifier, and any other technology required for specific body imaging. Most instruments collected in this accession group were created to be portable, hand-held, and connected to the electronic display unit for use. The objects were hand-held and designed for specific body parts because the crystals' low frequency (15m/c) required the transducer to be within 4cm of the tissue to produce a clear image. The display unit also included a camera to capture ultrasound images produced on the oscilloscope. John Wild imagined the opportunity for "mass-screenings" using this portable display unit and small, hand-held attachments and envisioned their use for the regular screening of common cancer sites, such as the prostate.
