Design for portability means considering
factors like size, weight, power,
magnetic field strength, cost, image
quality, and safety. Component selection
becomes very important for maintaining
stable and efficient power generation
and signal processing in a
smaller footprint.
Synergy of Technologies. It's becoming
more common to see hybrid
imaging technologies designed for a
more detailed view of the body. For example,
PET/MRI scans integrate PET
scans and MRI scans. MRI contributes
detailed images of internal body structures
and PET highlights functional
abnormalities using tracers. This is
particularly useful for cases of Alzheimer's
disease, epilepsy, and brain tumors.
In the past, this kind of holistic
analysis wasn't possible because MRI
magnets interfered with PET's imaging
detectors.
Ultrasound and OCT are another
complementary pair. When combined,
healthcare professionals can gather
high-resolution images of both superficial
and deep tissues and structures.
ADC
Since ultrasound is useful for capturing
functional images and dynamic
processes and OCT provides structural
imaging with fine details, combining
them offers a detailed structural and
functional assessment in a single scan.
This is particularly useful in specialties
like ophthalmology, cardiology, dermatology,
and oncology.
Advancements in medical imaging
technologies are changing the way
healthcare professionals approach diagnoses
and patients receive care.
These imaging modalities offer increasingly
detailed, accurate, and comprehensive
insights into the human
body. The ongoing trends toward higher
resolution, greater portability, and
hybrid imaging are part of a larger
trend toward precision medicine and
more personalized, efficient, and effective
healthcare.
