pulse-stepping motors driving a precision machine tool scanning table, under computer
control, acquiring counts from characteristic x and gamma rays in CAMAC scalers and
storing these in an LSI-1l in the CAMAC controller.
Data can be archived on floppy
discs for analysis and image production.
A monitor display will be included,
but
final high quality images will be produced in the nuclear medicine general purpose
image analysis computer (PDP 11/34 with a high-performance cisplay).
This system will provide high quality diagnostic images that scale precisely
to the anatomical size of the neck. Nodules can then be marked on the image to compare precisely what is felt by the physician and what is detected by the imaging
procedure.
The x-ray fluorescence scan provides information on the iodine content
of the thyroid that can be differentiated from findings on solid tumors by ultrasound imaging.
The x-ray fluorescence method yields data with low false negative rate; conveys very low radiation dose to the subject (< 100 mrem/study—-thyroid dose, essentially 0 whole body dose); and should be used in populations in which the risk of
thyroid cancer is high and where there {s reason to minimize radiation exposure.
One-half the cost of the system ($20,000)
patients.
is requested for studies of Marshallese
The balance of the cost will be requested in the Nuclear Medicine Program
budget area (HB-02-01).
A portable x-ray unit ($7,000) is required to replace a device that is expected
to be beyond economical repair.
The unit currently in use by Medical Team surveyors
is exposed to salt air and water.
It is essential that the survey team have equip-
mene that is reliable and as maintenance free as possible.
