The classical scanning mode where the variation of a focal plane if any is pre-calculated with a focus map and later the motorized XY stage captures optimally focused images by translating across the region of the scanning.
Uses single 40X or 20X objective combined with a secondary overhead camera for capturing preview (thumbnail) of the full slide including the barcode area.
Whole slide imaging is preferred over other modes when exhaustive image capture is needed for deferred access.

An all powerful scanning mode where multiple images covering all focal planes are captured at every field. The end result is essentially a whole slide scan mixed with pre-captured Z-stack at every position.
Similar to WSI mode, Volume scanning uses a single 40X or 20X objective combined with a secondary overhead camera for capturing preview (thumbnail) of the full slide including the barcode area.
Volume scanning is preferred over WSI when exhaustive image capture is needed for slides with overlapping cells such as Fine Needle Aspiration Biopsy slides, Pap smear slides etc.

Sketchy Medical Biochemistry is a specialized visual learning resource designed to help medical students master complex biochemical pathways, enzymes, and metabolic disorders using mnemonic-rich "sketches". By turning abstract molecular processes into memorable scenes, it simplifies topics often considered the most difficult in the first two years of medical school. Core Learning Methodology
Sketchy utilizes the "Method of Loci" (memory palace) technique:
Visual Symbols: Each enzyme, substrate, or clinical symptom is represented by a specific, recurring character or object (e.g., a "broken faucet" might represent a specific enzyme deficiency).
Narrative Flow: A narrator walks through the scene, explaining the biochemistry behind each symbol as it is drawn.
Spatial Anchoring: Symbols are placed in specific locations within the scene, helping students recall information by mentally "re-walking" the environment during exams. Key Content Areas Covered
Sketchy Medical organizes biochemistry into high-yield modules relevant to USMLE Step 1 and medical school curricula:
Metabolism: Detailed visual maps for Glycolysis, the TCA cycle, Gluconeogenesis, and Fatty Acid Oxidation.
Genetic Disorders: Visual breakdowns of Lysosomal Storage Diseases, Glycogen Storage Diseases, and Inborn Errors of Metabolism.
Molecular Biology: Mnemonics for DNA replication, repair mechanisms, and protein synthesis. sketchy medical biochemistry
Vitamin Deficiencies: Character-based representations of the clinical presentations of B-vitamin and fat-soluble vitamin deficiencies. Why Use Sketchy for Biochemistry?
Retention of "Heavy" Topics: Users report significant improvements in retaining information for dense subjects like amino acid metabolism compared to traditional textbooks.
Active Recall Integration: The platform often pairs videos with review cards to reinforce learning through active recall techniques.
Efficiency: It condenses lengthy textbook chapters into 10–20 minute videos, making it easier to review complex pathways multiple times. Recommended Supplemental Resources
While Sketchy is excellent for memorization, medical students often pair it with these authoritative texts for deeper conceptual understanding:
Lippincott Illustrated Reviews: Biochemistry: Best for clear diagrams and clinical correlations.
Vasudevan’s Textbook of Biochemistry: Highly recommended for foundational medical school curricula.
First Aid for the USMLE Step 1: Essential for identifying the highest-yield facts to focus on within Sketchy. How to Study Biochemistry - Sketchy Unique Visual Learning Approach : Sketchy's signature visual
Title: A Game-Changing Resource for Biochemistry Mastery - Sketchy Medical Biochemistry Review
Rating: 4.5/5
As a medical student, I can confidently say that Sketchy Medical Biochemistry has been a revelation in my journey to grasp the complex world of biochemistry. This comprehensive resource has not only helped me understand the intricacies of biochemical processes but also made learning engaging and fun.
Pros:
Cons:
Overall Experience: Sketchy Medical Biochemistry has been an indispensable resource in my biochemistry studies. The combination of visual learning, comprehensive coverage, and interactive features has helped me develop a deep understanding of biochemical concepts and retain them long-term. I highly recommend Sketchy Medical Biochemistry to any medical student or healthcare professional seeking to master biochemistry.
Recommendation: If you're struggling to understand biochemistry or want to reinforce your knowledge, Sketchy Medical Biochemistry is an excellent choice. Be prepared to invest time and effort, but rest assured that the returns will be well worth it.
Sketchy is a memory aid, not a physics textbook. It will not teach you why the free energy change of ATP hydrolysis is -30.5 kJ/mol. It will not teach you how to calculate pH buffers. You still need lecture notes or Board review books (like First Aid) for the conceptual why. Sketchy replaces the what (which enzyme is which), not the how. Enter the "Sketchy" method

Sketchy Medical (formerly Sketchy Micro/Pharm, now inclusive of Sketchy Biochem) is an alternative learning platform that utilizes visual mnemonics and narrative storytelling to teach complex scientific concepts. The Biochemistry curriculum is designed to tackle one of the most memorization-heavy and abstract subjects in medical school. By converting metabolic pathways, enzyme kinetics, and genetic disorders into "sketches" (animated scenes), the platform leverages the "Method of Loci" (Memory Palace technique) to improve long-term retention.
This report details the pedagogical approach, curriculum structure, strengths, limitations, and optimal integration of Sketchy Biochemistry into medical education.
Medical biochemistry education faces a tripartite dilemma: (1) the volume of intermediates, (2) the opacity of enzyme names (e.g., phosphofructokinase-1), and (3) the integration of pathways across cellular compartments. Traditional resources (Lehninger, Lippincott’s Illustrated Reviews) rely on linear diagrams and tables.
In contrast, the "Sketchy" approach uses cohesive visual narratives. A single scene contains recurring motifs: a character, a background action, and a color code representing a metabolic concept. The central question of this paper: Can the chaos of the Krebs cycle be tamed by a cartoon of a citric acid factory run by worker enzymes with distinct hats?
| Pros | Cons | |------|------| | Unforgettable for visual learners | Videos are 15–30 min each—long for biochem | | Integrates clinical correlates | Some symbols are forced/overloaded | | Excellent for Step 1 prep | Expensive ($30–40/month) | | Active recall + quiz features | Not comprehensive for PhD-level biochem | | Portable (mobile app) | Requires repeated review to stick |
Before we praise the solution, we must diagnose the disease. Medical biochemistry is difficult for three specific reasons:
Enter the "Sketchy" method, which solves problem #1 by turning enzymes into characters, and problem #3 by embedding pathology directly into the scenery.
