and certified by the Atomic Energy
Commission is the use of nuclearI
materials, will provide physicians
with a modern radioactive isotopeI
laboratory and full nuclear instru-
mentation for locating and meas
uring tumors in any part of the
body, including the brain.
NucIear diagnostic equipment to
be installed at Memorial by August
| includes a Picker Magnascanner,
used in connection with ingested or
injected radioactive materials to
locate and measure tumors or le-
SionS anywhere in the body, and a
number of other special ''scan-
ningp devices utilizing the same
principle.
These machines are activated by
the scintillation of different radio
active isotopes calcium, Stron-
tium, potassium, iodine 1876, gold,
radioactive Rose Bengal, and 9TH
eps = to operate styluses tracing
the outlines of different internal
organs and of tumors within or
attached to these organs, bones or
tissues.
DR.. Frank S. Tolone, Memorials
chief radiologist, will be in charge
of the Radiology section of h G
Institute and the administration
of therapy by x-ray and by new
$35 900 Picker Cobalt 60 radioiSo-
tope unit housing a tiny wafer of
radioactive cobalt produced by the
Atomic Energy Commission t
Oak Ridge, Tenn, and costing SILL
600. DR.. TOlone was an instructor
in radiotherapy at the Argonne
Cancer Research Hospital of the
University of Chicago before join
ing Memorials staff.
The Cobalt 60 kaleidoscope ma
chine will be contained in Speci-
ally constructed room built to
Atomic Energy Commission speci-
fications. The concrete walls OF
the building will be AZ inches thick
to shield trained technicianS from
gamma radiation in the degree OF
1000 Roentgen units per hour and
/ $3.50, 900 electron volts.
More compact and flexible than
an x-ray unit of equivalent power,
the Cobalt go unit emits an invisi-
BILE beam of gamma rays that can
penetrate into the body in the pre-
determined depth of 1887 inches,
hitting diseased tissue in an exact
ly measured and blocked area,
yet Sparing skin and surface tissue
by means of mechanical rotation
of the 'warhead" containing the
ray-emitting isotope material.
DR.. John T. Wrzesinski will be
in charge of the Institutes ChemO-
Therapy Division, which will be
affiliated with the National Insti-
tutes of Health, the University Of
California Medical Center at Los
Angeles, and the Arizona State De-
partment of Health. This division
will become operational by Sep
tember 1 under present plans, and
supplies of tested compounds for
clinical use and for research are
now being stocked by the hospital.
DR.. William P. Longmire, MD,
professor of surgery and chairman
of the Department of Surgery at
the U.C.L.A. School of Medicine,
heads the western states sub-group
of the national chemO-therapy pro-
gram. His selection of Memorial
as one of the 20 western hospitals
to take part in the research pro-
iect was a compelling factor in
the decision of Memorials trus-
tees to organize the Institute for
complete diagnosis and therapeu-
tic procedures.
The Chemo Therapy Division
will observe procedures laid down,
by the Cancer Division of the Ma
tional Institutes of Health for the
screening of chemical compounds
being evaluated in cancer treat
ment. Strict controls for the screen
ing program were established
