Laser computed tomography

What are the advantages of CT laser mammography?
Advantages.
It does not use ionizing radiation like in the case of Mammography, SPECT.
It has higher sensitivity and specificity for imaging dense breast tissue.
It does not require contrast agent unlike MRI..
What are the disadvantages of CT laser mammography?
The first is ionizing radiation.
Since mammography uses low-energy x-rays to image the breast, the breast is exposed to ionizing radiation.
Too much repeated exposure can elevate the risk of cancer down the road.
The second drawback is inaccuracy..
What is CT laser?
Computed Tomography Laser Mammography (CTLM) is a relatively new and very promising field of optical imaging.
In combination with conventional mammography and other techniques, it has the power to provide detailed information of breast abnormalities..
During breast CT, you lie face down on a table while a CT scanner rotates around the breast.
The total dose of radiation is the same as in a conventional mammogram.
Research on breast CT for screening is still in the early stages, however. — Last updated on July 27, 2022 at 6:44 AM.

The technology uses laser in the same way computed tomography uses X-Rays, these beams travel through tissue and suffer attenuation. A laser detector measures the intensity drop and the data is collected as the laser detector moves across the breast creating a tomography image.

CTLM is a non-invasive practical system that uses near-infrared laser light propagation through the tissue to assess its optical properties.

It is a painless, non-invasive, breast imaging system that does not require breast compression or exposure to radiation. It has the potential to be combined with other diagnostic tools such as mammography, ultrasound, MRI, and positron emission tomography, and is found to increase the sensitivity of the results.

This medical imaging technique uses laser energy in the near infrared region of the spectrum, to detect angiogenesis in the breast tissue. It is optical HistoryMechanismApplicationComparison with other

Measurement device

A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path.
Since there are many types of lasers — ultraviolet, visible, infrared, continuous wave, pulsed, high-power, low-power — there is an assortment of instrumentation for measuring laser beam profiles.
No single laser beam profiler can handle every power level, pulse duration, repetition rate, wavelength, and beam size.
