CT Systems: An In-Depth Look
Known as computed tomography systems or computed tomography CT, these systems have revolutionized medical imaging with their detailed body views surpassing conventional X-rays. They use a rotating X-ray source and detectors to capture precise cross-sectional images of the body through computed axial tomography. The X-ray source in a CT system emits narrow beams of X-rays that pass through the patient’s body, creating an X-ray image. As these rays pass through, detectors within the CT system capture them.
The process of obtaining a computed axial tomography scan, also known as CT scan, involves the following steps:
-
The patient is positioned on a table that slides into the CT scanner.
-
X-ray beams are emitted from multiple angles around the patient’s body.
-
The captured X-rays are then transmitted to a computer, which reconstructs them into detailed images.
-
These images provided by CT systems offer greater clarity and more detailed information than conventional X-ray images, allowing for an accurate diagnosis of various medical conditions.
-
CT scans are used not only for detecting bone fractures but also for viewing soft tissues and blood vessels.
-
Contrast dye, also known as contrast material, can be used to highlight certain areas, making it easier to observe internal injuries or abnormalities.
As you are aware, CT scanners, also known as CAT scan machines, have been instrumental in examining internal organs, soft tissues, and solid organs [1]. A CT imaging system generates a detailed cross-sectional view that provides more detailed information than traditional chest X-ray or spiral CT. One of the key elements of the CT system is the CT fan beam, which is responsible for emitting the narrow beams of X-rays.
These CT images are instrumental in diagnosing diseases, monitoring therapy, and planning surgeries. For instance, a CT angiogram can give detailed images of blood vessels in the brain, aiding in the diagnosis of vascular diseases. With a CT examination, doctors can visualize the entire structure of the patient’s digestive system, from the esophagus to the rectum, assisting in the diagnosis and treatment of digestive diseases. The detailed images provided by CT scans make it an invaluable tool in modern healthcare.

Enhancements in resolution and speed
-
The integration of artificial intelligence
Each of these advancements brings its own unique benefits, and collectively, they are transforming the way we use CT technology. Let’s go over them in detail.
Reduced Radiation Dose
Radiation exposure, a potential risk posed by any imaging form using ionizing radiation like CT scans, remains a key concern in developing cancer [2]. However, modern CT scanners have made significant strides in minimizing this risk, focusing particularly on reducing the radiation dose.
Automatic exposure control (AEC) systems in modern CT scanners adjust the radiation based on the patient’s size and shape, minimizing unnecessary exposure. This is particularly important when performing pediatric imaging, where the ALARA principle – ‘As Low As Reasonably Achievable’ – is crucial for safety.
Photon-counting CT scanners have been particularly instrumental in this regard. These scanners enhance geometrical dose efficiency, which leads to reduced radiation doses for patients. This technology, introduced by Siemens Healthineers in the form of the NAEOTOM Alpha, has marked a significant advancement in CT technology.
Additionally, real-time dose monitoring in CT scanners enables on-the-fly adjustments to radiation levels, ensuring patient radiation safety throughout. This feature allows the scanner to adapt to the specific needs of the patient without compromising image quality.
The focus on reducing radiation dose is not limited to the technology alone. Optimizing CT facility quality assurance involves using protocols that apply the lowest radiation dose possible while maintaining image quality. This approach ensures that the benefits of CT scans can be achieved with the least possible risk.
Improved Image Reconstruction Techniques
Besides reducing radiation dose, CT scan machine technology has made remarkable progress in enhancing image reconstruction techniques. Image reconstruction is the process by which the data captured by the CT scanner is converted into cross-sectional images. This process is integral to the quality of the CT images and, consequently, the accuracy of the diagnosis [3].
Historically, filtered backprojection (FBP) was the predominant reconstruction method. However, new iterative reconstruction techniques are now replacing it to improve image quality, particularly at reduced radiation doses. One such technique is model-based iterative reconstruction (MBIR). MBIR offers the following benefits:
-
Significantly improves spatial resolution
-
Reduces noise
-
Lower image noise and higher resolution than FBP
-
Accurate diagnosis
-
Better patient outcomes
Artificial intelligence (AI) and deep learning have also found their way into CT image reconstruction. The integration of these technologies shows substantial promise for:
-
Enhanced image quality
-
Potential for additional radiation dose reductions
-
Improved diagnostic accuracy
-
Increased efficiency
-
Potential reduction in healthcare costs.
Physical factors are now more accurately incorporated into image reconstruction, leading to improvements in image quality. In addition, advanced algorithms like ADMIRE reduce artifacts, and noise reduction techniques fine-tune the balance between high-contrast resolution and low-contrast detectability.
Photon-Counting
Of all the innovations in CT technology, the emergence of photon-counting CT arguably stands as the most revolutionary. This technology streamlines the conversion of X-ray photons into electrical signals, a process that was traditionally a two-step conversion involving visible light. This change has brought about significant improvements in image quality and safety.
Traditionally, X-ray photons were first converted into visible light, which was then converted into an electrical signal. However, the introduction of the NAEOTOM Alpha, a photon-counting CT by Siemens Healthineers, has changed the game. This technology directly converts X-ray photons into electrical signals, skipping the visible light conversion step.
As a result of this streamlined process, photon-counting CT offers several advantages:
-
Preserves all of the original X-ray information
-
Provides radiologists with high spatial resolution CT data
-
Improves contrast-to-noise ratio
-
Produces imagery with no electronic noise
-
Results in a lower radiation dose with intrinsic spectral information.
The introduction of photon-counting technology is truly a testament to the continuous evolution and advancement of CT technology. It underscores the relentless pursuit of improved patient safety, superior image quality, and enhanced diagnostic precision in the world of medical imaging.
