Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...

Background:

Accurate breast imaging is crucial for early disease detection.
Existing modalities like diffuse optical tomography (DOT) and photoacoustic tomography (PAT) offer complementary information but require separate systems.
Integrating DOT and PAT can enhance imaging capabilities for breast cancer diagnosis.

Purpose of the Study:

To design, fabricate, and test a novel integrated imaging system fusing DOT and PAT.
To leverage the strengths of both DOT and PAT in a single platform for breast imaging.
To evaluate the potential of this dual-modality system for quantitative functional and cellular imaging of the breast.

Main Methods:

Development of a hybrid imaging platform integrating DOT and PAT instrumentation.
Fabrication of the combined system with optimized optical and acoustic detection.
Initial validation using tissue phantoms to assess imaging performance.

Main Results:

Successful design and fabrication of a novel fused DOT and PAT imaging system.
Demonstration of the platform's capability to acquire dual-modality images.
Initial phantom studies indicate potential for quantitative functional and cellular imaging.

Conclusions:

The integrated DOT and PAT platform represents a promising advancement in breast imaging technology.
This dual-modality approach has the potential to provide comprehensive quantitative imaging for improved breast cancer assessment.
Further validation with biological tissues is warranted to fully realize the clinical potential.
