OCT
2D and 3D cross-sectional optical coherence tomography
(OCT for short) can image biological tissue at a resolution of about 2-10μm,
and at depths of 1-3mm. This can have very significant impacts on noninvasive
or minimally invasive clinical diagnosis of surface tissue growth and repair.
Fourier domain optical coherence tomography, based on a phase-resolved method
where phase information was retrieved from the reconstructed complex fringe
signals, can see the fluid flow in tiny vessels. Theoretically, the value of
phase differentiation of one scanned point is proportional to the flow velocity
there. But due to the small phase differentiation and strong background noise,
the imaging quality is limited till now. Now I am working on improving imaging
quality by using signal processing algrithms including hardware design and
optimization and imaging processing.
Nuclear Imaging(PET and SPECT)
Nuclear imaging uses low doses of
radioactive substances linked to compounds used by the body's cells or
compounds that attach to tumor cells. Using special detection equipment, the
radioactive substances can be traced in the body to see where and when they
concentrate. Two major instruments of nuclear imaging used for cancer imaging
are PET and SPECT scanners.
I once did my master project on designing a detector of
a SPECT system using CZT. It was an interesting experience and i am still
interested in developing nuclear imaging system including both software and
hardware..
