1. MODERN IMAGING MODALITIES
WITH RECENT INNOVATION
GRINTY BABU

2. Modality, a method of
diagnosis. Modality (medical
imaging), a type of equipment
used to acquire structural or
functional images of the body.
What is Modality in medical terms?

3. A variety of imaging
techniques such as X-ray
radiography, ultrasound, CT, nuclear
medicine including positron
emission tomography (PET),
Magnetic resonance imaging (MRI)
are used to diagnose or treat
diseases.
What are the modalities of radiology?

4. These emerging
technologies could enhance
medical imaging by
providing better resolution,
enabling new modalities, or
facilitating portability.

5. 1.Hyperspectral Imaging
By applying an optical semiconductor technology
commonly used in digital color projectors to an
imaging technique employed by the defense
industry, Karel Zuzak, senior biomedical research
engineer, has shed light on an array of potential
optical medical imaging applications. The
resulting hyperspectral imaging system could help
reduce the risk of complications during various
medical procedures and associated liability.

Hyperspectral imaging, like other
spectral imaging, collects and processes
information from across the
electromagnetic spectrum. The goal
of hyperspectral imaging is to obtain the
spectrum for each pixel in the image of a
scene, with the purpose of finding objects,
identifying materials, or detecting
processes.

7. 2. Electromagnetic
Acoustic Imaging
A patented imaging technology offers higher
clarity at a lower price than conventional
imaging modalities, according to its developers
at the University of Oxford. Oxford
electromagnetic acoustic imaging (OxEMA)
employs electromagnetic and acoustic waves
to produce what the researchers claim is
"unparalleled tissue-type characterization in
this price bracket." The technology could allow
for faster and easier diagnosis of various types
of cancer.

8. MM.DD.20XX8
Electromagnetic acoustic imaging (EMAI) is
a new imaging technique that uses long-
wavelength RF electromagnetic (EM) waves
to induce ultrasound emission. Signal
intensity and image contrast have been
found to depend on spatially varying
electrical conductivity of the medium in
addition to conventional acoustic
properties.

9. 3. Superconducting Magnet
System
MRI is crucial for performing a range of medical
diagnostic applications, but the size and cost of the
superconducting magnets and cooling systems used
in MRI equipment make the machines stationary
and expensive. Now, researchers at Japan’s Railway
Technical Research Institute have developed a
superconducting magnet system that can fit in the
palm of a hand. The compact magnet, in turn, could
lead to the development of enhanced mobile
imaging applications.

Type II superconductors such as niobium-
tin and niobium-titanium are used to make
the coil windings for superconducting
magnets. These two materials can be
fabricated into wires and can withstand
high magnetic fields.

11. 4. Wafer-Scale Mega
Microchip
A large microchip developed by scientists at
the University of Lincoln (UK) is designed to
enhance medical imaging applications. Measuring a
whopping 12.8 cm square, the chip could eventually
aid in the diagnosis of cancer, enabling doctors to
see the impact of radiotherapy treatment more
precisely.

Dubbed 'DynAMITe,' the wafer-scale chip
produces images that will clearly show the
effects of radiation on tumors and help
doctors to detect them earlier. And
because it is strong, the chip can survive
many years of exposure to radiation.
