Includes radiographic and fluoroscopic equipment for routine and
special x-ray procedures. Equipment is available for direct digitization
of high-resolution fluoroscopically-generated images. This technique
permits computer manipulation and analysis of the fluoroscopic images.
Each clinical facility is provided with state-of-the-art Computed
Tomography equipment. These units produce high-resolution images of
internal human anatomy which are displayed as submillimeter
distributions of tissue radiation attenuation coefficients. The
Department operates a Magnetic Resonance Imager. Both 1.5 and 3 Tesla
units produces anatomical images of the distribution of hydrogen/proton
concentrations within tissue. This instrument makes available the most
recent diagnostic procedures and offers the potential for considerable
research as well.
MEDICAL ULTRASONOGRAPHY utilizes the principle of sonar
to produce cross-sectional images of various organ and tissue
interfaces in the body which are able to reflect high-frequency sound.
Numerous units of various types are available for clinical and research
BI-PLANE - VASCULAR & INTERVENTIONAL SUITE utilizes
high dose fluoroscopy for vascular imaging studies and repair, cardiac
procedures and any procedure where time resolved x-ray imaging is
MAMMOGRAPHY is the special application of x-ray
technology for detection of very small objects and low contrast objects
in breast tissue. Mammography Quality Assurance Testing is one of
several clinical experiences offered to first and second year graduate
Graduate students also receive hands on instruction from the medical physics faculty.
COMPUTED TOMOGRAPHY (CT) uses series of x-ray images to
provide various reconstructed views (including 3D images) of patients
for critical care investigations, surgical planning, interventional
procedures and highly accurate anatomic modeling.
MAGNETIC RESONANCE IMAGING (MRI) uses powerful magnets
and a series of high frequency pulses to obtain various reconstructed
views. This type of imaging does not include the use of ionizing
radiation and may be a viable alternative (as well as generally
providing very high soft tissue contrast) for more vulnerable (radiation
dose intolerant) populations.
NUCLEAR MEDICINE deals with the applications of
incorporated radioactive material, excluding brachytherapy, for
diagnoses and treatment of diseases. Nuclear medicine procedures use
radionuclide-labeled pharmaceuticals and scintillation crystal cameras
to obtain the distribution pattern of the pharmaceuticals and to measure
organ or tissue function, blood flow, or the presence of malignancy.
The localization of the pharmaceuticals is used effectively for
therapeutic radiation treatment as well as for palliative applications.
Several of the recently developed scintillation camearas and computer
systems are available in each of the nuclear medicine sections on campus
and may be used for research purposes. (PET/CT pictured on right and
Cymbia SPEC/CT Gamma Camera shown below.)
RADIATION BIOLOGY is the study of the effects of
ionizing radiation on living things. Instrumentation is available to
perform a variety of cellular and molecular techniques for the study of
DNA damage and repair, changes in gene and protein expression, cell
cycle regulation, and apoptosis. Students will have the opportunity to
conduct radiobiology experiments to elucidate the mechanisms of
radiation-induced cell killing, heat-radiosensitization, and effects of
heat-shock and chemotherapeutic agents on cultured mammalian cells. In
addition, students have access to several core facilities located on the
