While some older microscopes had only one lens, modern microscopes make use of multiple lenses to enlarge an image. There are two sets of lenses in both the compound microscope and the dissecting microscope (also called the stereo microscope). Both of these microscopes have an objective lens, which is closer to the object, and an eyepiece, which is the lens you look through. The eyepiece lens typically magnifies an object to appear ten times its actual size, while the magnification of the objective lens can vary. Compound microscopes can have up to four objective lenses of different magnifications, and the microscope can be adjusted to choose the magnification that best suits the viewer’s needs. The total magnification that a certain combination of lenses provides is determined by multiplying the magnifications of the eyepiece and the objective lens being used. For example, if both the eyepiece and the objective lens magnify an object ten times, the object would appear one hundred times larger.

Innovations in imaging technologies are delivering on the promise of precision health with diagnostics, therapies, and monitoring, enabling clinicians to provide the optimal care for each patient. Digitization and AI solutions are driving connectivity across the healthcare enterprise to:

A microscope is an instrument that is used to magnify small objects. Some microscopes can even be used to observe an object at the cellular level, allowing scientists to see the shape of a cell, its nucleus, mitochondria, and other organelles. While the modern microscope has many parts, the most important pieces are its lenses. It is through the microscope’s lenses that the image of an object can be magnified and observed in detail. A simple light microscope manipulates how light enters the eye using a convex lens, where both sides of the lens are curved outwards. When light reflects off of an object being viewed under the microscope and passes through the lens, it bends towards the eye. This makes the object look bigger than it actually is.

Advanced medical imaging exams with complex scanning protocols and processing requirements are performed on a regular basis, and the volume of medical imaging data has grown exponentially due to the advances in imaging technology.[3] It has become more challenging to optimize the workflow with solutions that accommodate all the necessary requirements for each exam. Radiology departments are looking to increase efficiencies and operate with maximum productivity and detailed resource planning.

Basics ofimaging

Though modern microscopes can be high-tech, microscopes have existed for centuries – this brass optical microscope dates to 1870, and was made in Munich, Germany.

A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is.

Leading organizations are reorienting their customer experience efforts by ramping up remote accessibility and digital deliverables. GE HealthCare continues to invest in improving accessible online training and education, remote system maintenance, and monitoring capabilities.

The dissecting microscope provides a lower magnification than the compound microscope, but produces a three-dimensional image. This makes the dissecting microscope good for viewing objects that are larger than a few cells but too small to see in detail with the human eye. The compound microscope is typically used for observing objects at the cellular level.

A 20x objective with a field number of 18 would actually have a FOV of 0.9 mm. Likewise, a 100x objective with a field number of 18 would have a FOV of 0.18 mm.

Precision imaging assists in diagnosing disease with improved accuracy, better delineating disease subtypes, defining prognoses, and informing treatments for oncological and non-oncological disorders. Precision imaging is descriptive, predictive, and integrative—effectively moving acquired data to clinical insights.[2] Imaging data is a critical component of the clinical information that can enable precision diagnostics and therapeutics, leading to newer techniques such as theranostics.

Over the course of the microscope’s history, technological innovations have made the microscope easier to use and have improved the quality of the images produced. The compound microscope, which consists of at least two lenses, was invented in 1590 by Dutch spectacle-makers Zacharias and Hans Jansen. Some of the earliest microscopes were also made by a Dutchman named Antoine Van Leeuwenhoek. Leeuwenhoek’s microscopes consisted of a small glass ball set inside a metal frame. He became known for using his microscopes to observe freshwater, single-celled microorganisms that he called “animalcules.”

Limited or no access to care is one of the primary factors related to health disparities, which are often caused by socially determined circumstances and can result in poor patient outcomes. The inability to access important components in the care path, such as medical imaging, can have a dramatic effect on health outcomes. Advances in medical imaging have greatly improved the accuracy of disease screenings and aid clinicians in diagnosing diseases earlier. Without these advances, these diseases might not be detected until they reached a stage that’s much more life-threatening.[1] Despite its importance in the care pathway, many patients have insufficient access to medical imaging for a variety of reasons.

Advantages and disadvantages of digital radiography

By leveraging AI and machine learning technologies, innovative solutions can help increase efficiencies across the entire radiology workflow without increasing the administrative and training burden on clinicians.

“We’re helping radiologists and technologists with efficient solutions to transform their workflow,” said Miller. “We’re rethinking the workflow experience to make it more intuitive and increasing efficiencies with AI-based solutions.”

Disadvantages of digital radiography

Digitization and AI in healthcare are part of an era-defining reality. AI tools can seek, collect, store, and standardize medical data and assist with repetitive tasks. They can also support clinicians with fast, accurate, and precise clinical information to inform their evaluations, diagnoses, and treatments. AI’s introduction into the healthcare space was slow by comparison to other industries and the consumer market, but several factors helped speed the digital transformation in healthcare, including COVID-19.

With more precise and integrated care, imaging diagnostics and therapeutics are impacting clinical outcomes across the patient care journey, in areas such as prostate cancer, breast cancer, and more.

The availability and adoption of AI applications to aid in radiology workflow optimization is quickly growing, positively impacting exam set-up, protocoling and patient positioning. AI-based tools are alleviating the time demands on radiology workflows, providing better standardization that allows radiology staff to spend more time on patient care.
