Capital Equipment Requirements for BY (FY 1982)
Automation of medical records of Marshall Island patients is required to
obtain detailed analyses which must be performed manually and which are sometimes
not practical with existing manpower.
To use automated equipment for processing
data requires purchase of input and output devices ($10,000) for the recording and
retrieval of patient data.
Medical record equipment necessary to automate records includes devices to

generate, and read microfiche records, and produce “hard copy" of records from

microfiche.

The system is estimated to cost $30,000.

Computer capability within the Medical Department is provided by a Xerox computer that is in excess of 13 years old.
Xerox is no longer in the data processing
field, spare parts are difficult to obtain, and system hardware changes are all but
impossible.
To provide computer capability necessary to automate medical data of
the Marshall Island patients,this program will share $10,000 of the total cost for
replacing and upgrading the equipment.
A thyroid scanning system for combined x-ray fluorescence and radionuclide

imaging studies is necessary to identify nodules of interest.

a large, high-priority germanium detector

(6 cm diameter,

The system employs

2 cm thick)

in a vertical

mount; the isotope exciting source is 170Tm( ti, = 134d; 51, 52 + 59 kev x rays) which
is produced and available at BNL in high purity and in large amounts.
The system
uses 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-ll 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 display).

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.

In summary, the x-ray fluorescence method yields data with low false negative

One-half the cost of the system ($20,000) is. requested for studies of Marshallese patients.
The balance of the cost will be borne by the Nuclear Medicine
Program.
