Scientific accuracy
Developed from verified medical references and aligned with current anatomical and clinical standards. Consistent terminology and visual hierarchy across complete publications.
Clarity for complex concepts
Illustrations remove unnecessary visual noise and focus on essential structures and processes, improving comprehension for students, researchers, and patients.
A structured process
From briefing to final delivery: sketch approval rounds, precise refinement, and publication-ready files, delivered on schedule.
Bridging complex medical science and visual clarity
Each illustration is developed through a structured process combining scientific research, visual strategy, and precise execution.
In medicine and healthcare, precision is essential. Whether you’re publishing scientific research, developing educational materials, preparing clinical documentation, or explaining treatments to patients, the effectiveness of your communication depends on accuracy and clarity.
Medical illustration fills the gap where words, photographs, or generic visuals fall short. Complex anatomical structures, surgical procedures, cellular mechanisms, and pathological processes demand carefully designed visual explanations. As a professional medical illustrator, I translate intricate medical and biological information into clear, accurate visuals that enhance understanding, education, and professional communication.
At Karin Spijker, medical illustration is never decorative. Each illustration is designed to serve as a precise communication tool grounded in scientific accuracy, optimized for visual clarity, and customized for its intended purpose and audience.
“I have worked with Karin Spijker for many years on various visual projects. The greatest common denominator in these projects is a qualitative, professional image delivered on time. Karin is entirely at home in both fields, whether an illustration or high-end image editing on photo material.”
Pauline Speelman, Signorita“Karin Spijker has performed assignments for me several times to my complete satisfaction, such as logos and two 3D animations. Karin can translate the information from a briefing into the desired end product and can think along with you pleasantly. In doing so, she works accurately, follows the set timetable, and honors her appointments. Karin is also a charming person to work with.”
Natasja Kardos, Seahorse Solutions“For my clients, I have asked Karin Spijker more often for customized assignments, especially for more specialized image editing. Karin can conjure up software like Adobe Photoshop and Illustrator. She is very meticulous and also communicates about progress. I highly recommend Karin, her work, and her pleasant cooperation.”

What is medical illustration?
Medical illustration is essential for translating complex medical information into clear, accurate visual communication.
Medical illustration is a specialized discipline at the intersection of medicine, science, and visual communication. Its purpose is knowledge transfer, not aesthetic embellishment.
A well-designed medical illustration:
- isolates essential structures
- removes visual noise
- visualizes processes that cannot be photographed
- presents information in a way that supports learning and decision-making
Unlike photography, which captures everything indiscriminately, medical illustration offers a curated, didactic view of reality. Blood, overlapping tissues, and irrelevant details can be omitted, while key anatomical relationships and mechanisms are highlighted.
This makes medical illustration indispensable in healthcare, research, education, and professional communication.
Medical drawings are essential in healthcare
When and why medical illustration is essential
Medical illustration is used whenever accuracy, clarity, and credibility matter. Typical applications include:
- Scientific publications and journals
Clear figures and visual abstracts that improve readability and impact. - Medical and anatomical education
Teaching materials for universities, medical schools, and training programs. - Clinical and surgical communication
Step-by-step visualization of procedures, techniques, and anatomical relationships. - Patient communication and informed consent
Approachable visuals that help patients understand diagnoses and treatments without unnecessary distress. - Pharmaceutical and biotech communication
Visualizing mechanisms of action, biological pathways, and therapeutic concepts. - Medico-legal and forensic contexts
Objective illustrations that clarify medical findings in legal documentation.
In all these contexts, medical illustration supports accuracy, reduces misinterpretation, and strengthens professional credibility.
Custom medical illustration versus stock images and AI tools
When searching for visual content, many organizations consider stock imagery or AI-generated visuals. Custom medical illustrations ensure accuracy, clarity, and reliability, where generic visuals often fall short.

AI tools do not understand anatomy or biological function; they reproduce visual patterns without scientific reasoning. In medical and scientific contexts, even small inaccuracies can undermine trust or lead to serious misinterpretation. Custom medical illustration provides verified accuracy and accountability.
Where can I find a good medical illustrator?
This is a common question among publishers, healthcare professionals, and research institutions.
A good medical illustrator combines:
- scientific and anatomical knowledge
- visual communication expertise
- experience with medical and academic workflows
The title “medical illustrator” is not protected, so careful selection is essential. Look beyond aesthetics and evaluate whether an illustrator demonstrates scientific understanding, clarity of explanation, and a structured working process.
As a certified and experienced medical illustrator, I work closely with medical professionals, researchers, and publishers. I understand medical terminology, workflows, and publication standards, allowing for efficient collaboration and reliable outcomes.
Examples of medical illustration
Medical illustration can take many forms, depending on the subject and audience. Common examples include:
- Anatomical illustrations
Detailed depictions of organs, muscles, vessels, and systems. - Surgical illustrations
Clear visualization of procedures, instruments, and anatomical relationships. - Cellular and molecular illustrations
Visualizing biological mechanisms and processes invisible to the naked eye. - Educational diagrams
Structured visuals for textbooks, e-learning platforms, and training materials. - Patient-focused illustrations
Clear, non-confrontational visuals supporting understanding and compliance.
Each illustration is tailored to its specific purpose, level of detail, and target audience.
How much does medical illustration cost?
Medical illustration pricing depends on several factors. There is no fixed price list, as each project is custom-made.
Key factors influencing cost include:
1. Complexity and technique
Simple line drawings differ significantly from detailed full-color or 3D illustrations.
2. Time and scope
Research, sketching, revisions, and final production all contribute to the project scope.
3. Usage and licensing
Internal educational use differs from worldwide publication or commercial distribution.
I work transparently and provide a clear quotation in advance, tailored to your project’s scope and intended use. Medical illustration should be viewed as a long-term investment. Accurate visuals can be reused across publications, presentations, and educational materials for years.
