Summary
Breast CT offers a promising alternative to mammography for breast cancer imaging. This advanced computed tomography technology is well-suited for breast imaging, reducing artifacts and improving visualization for interventional procedures.
Area of Science:
- Radiology
- Medical Imaging
- Biomedical Engineering
Background:
- Mammography has been a standard for breast cancer screening for over 30 years.
- Advancements in digital detectors have improved mammography, while other imaging modalities like computed tomography (CT) have also evolved.
- Large field-of-view flat panel detectors have facilitated the development of specialized CT applications, including breast CT.
Purpose of the Study:
- To explore the potential of cone beam CT for breast imaging.
- To design a novel breast CT system for image-guided interventional procedures.
- To prepare for multi-institutional clinical trials to assess the role of breast CT in clinical practice.
Main Methods:
- Utilizing cone beam geometry for CT imaging of the breast.
- Leveraging the anatomical characteristics of the breast (lack of bone, natural tapering) to minimize CT artifacts.
- Developing a third-generation prototype breast CT system.
Main Results:
- The breast's anatomy is well-suited for cone beam CT, reducing common artifacts.
- The tapering of the breast minimizes X-ray path lengths, further reducing cone beam artifacts.
- A new prototype system is being designed for interventional procedures.
Conclusions:
- Breast CT shows significant potential as an advanced imaging modality.
- The technology is particularly advantageous due to reduced artifacts compared to other CT applications.
- Future clinical trials will establish the role of breast CT in breast imaging and interventions.

01:29Positron 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...

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...

01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
