Lasers in Cardiothoracic Surgery
Patrick W. Domkowski, G. Chad Hughes, John E. Scarborough, Luis H. Diodato, Monica L. Smith, Kevin P. Landolfo, and James E. Lowe
Transmyocardial laser revascularization (TMR) is emerging as a potential treatment option for path end-stage coronary artery disease who are not candidates for coronary
angioplasty or bypass surgery.
The Origins of 3D Optical Imaging of Cataracts
Barry R. Masters
What do optical biomedical imaging applied to cataract re- search and aerial photogrammetry have in common? The work of
Theodor Scheimpflug, an Austrian optics pioneer of the late nineteenth and early twentieth
centuries, connects these diverse fields. This fascinating story illustrates the fundamental
connection between optical developments for military aerial photogrammetry and today’s world of biomedical imaging. It also demonstrates that in the rapidly evolving field of optics, one can
never predict what will develop from one’s research.
Ultraviolet Rays Tested in Fight Against Tuberculosis
The use of ultraviolet germicidal irradiation for the disinfection of airborne infectious particles to prevent transmission of
diseases is an old technology that has yet to mature due to a lack of real world testing. Enough has been learned through extensive research and long experience, however, to make the technology useful today
while researchers continue to learn.
Greater knowledge, through ongoing re-
search and closely monitored installations,
may determine conclusively whether
UVGI air-mixing systems can make a ben-
eficial difference in TB control. If proof
can be established in difficult settings such
as homeless shelters that TB spread can be
reduced by UVGI, the technology can be
applied broadly. Clinics, prisons, long-
term care facilities, schools, and public
transportation networks are examples of
sites where this cost-effective strategy
could be applied.
