Vitamin D plays a critical role in maintaining bone health, supporting immune function, and reducing inflammation. With growing awareness of vitamin D deficiency and its health implications, more people are seeking ways to accurately check their vitamin D levels.

 

1. Why Test for Vitamin D?

• Vitamin D deficiency is surprisingly common, especially in individuals who:
• Spend limited time outdoors
• Live in areas with limited sunlight
• Follow vegan diets or have digestive conditions
• Are elderly, obese, or have darker skin
• A deficiency in vitamin D can lead to:
• Osteomalacia or rickets (soft bones)
• Increased risk of fractures
• Weakened immune response
• Muscle weakness and fatigue

Routine testing is essential for at-risk individuals or anyone wanting to optimize their long-term health.

 

2. Common Types of Vitamin D Tests

There are two primary forms of vitamin D that can be measured in the blood:

Test Name	What It Measures	Pros	Cons
25-hydroxyvitamin D [25(OH)VD]	The main circulating form	Gold standard for assessing deficiency	May not reflect real-time biological activity
1,25-dihydroxyvitamin D [1,25(OH)₂D]	The active hormone form	Useful in specific diseases (kidney issues)	Not recommended for general screening

Among these, 25(OH)VD is the preferred and most reliable marker for evaluating vitamin D status.

 

3. Testing Technologies: Which Is Most Accurate?

Vitamin D levels can be tested using various technologies:

Technologies	Principle:	Pros	Cons
Immunoassays (e.g., CLIA – Chemiluminescence Immunoassay)	Detects 25(OH)VD through a highly sensitive reaction between antigens and antibodies.	Fast, automated, cost-effective, widely used in clinical laboratories.	Conventional analyzers often require large spaces and significant investment.
LC-MS/MS (Liquid Chromatography–Mass Spectrometry)		Very accurate, can detect multiple forms of vitamin D.	Expensive, requires specialized equipment and skilled technicians.
Home Test Kits		Convenient, no lab visit needed.	Limited accuracy, inconsistent quality, often based on dried blood spot collection.

1.Improvements at the hardware level

(1) Increase the scanning speed

Frequency domain OCT (FD-OCT) : Compared with time domain OCT (TD-OCT), FD-OCT has A faster scanning speed (up to tens of thousands to hundreds of thousands of A-scans per second), significantly reducing artifacts caused by patients’ minor movements (such as eye tremors and breathing).

Swept-frequency OCT (SS-OCT) : By rapidly tuning the laser light source to achieve high-speed scanning, it further shortens the single imaging time.

(2) Eye-tracking system

Real-time active tracking: In ophthalmic OCT, infrared cameras or pupil tracking technology (such as Zeiss’s Follow-Up Mode) are integrated to dynamically adjust the scanning position to compensate for eye movement.

Adaptive scanning: Adjust the scanning path based on real-time tracking data to avoid image shift caused by sudden movement of the patient.

(3) Probe stability design

Handheld OCT: For non-cooperative patients (such as children and Parkinson’s disease patients), lightweight probes or head fixation devices (such as jaw supports) are used.

Contact OCT: In intravascular OCT (IVOCT), the movement caused by heartbeats or breathing is reduced by touching the vessel wall through a catheter.



2. Correction of software algorithms

(1) Image Registration

Feature point matching: Align B-scan images from multiple scans using stable anatomical structures in the image (such as retinal vascular bifurcations).

Registration based on mutual information: Motion compensation is achieved by maximizing the similarity index between images (such as normalized mutual information).

(2) Motion detection and rejection

Abnormal frame detection: Identify invalid frames caused by intense movement (such as signal loss and distortion) and eliminate them during reconstruction.

Dynamic weighted average: Weights are assigned to images scanned multiple times (frames with smaller motion have higher weights), and the influence of random motion is reduced after fusion.

(3) Deep learning for artifact removal

Generative Adversarial networks (Gans) : Train models to restore clear structures from motion-degraded images (such as Artifact-Net).

Time series prediction model: Utilizing networks such as LSTM to predict eye movement trajectories and correct scanning positions in advance.



3. Optimization of operation processes

(1) Patient preparation

Fixed position: During ophthalmic examinations, use a head support and a forehead support, and remind the patient to avoid speaking or swallowing.

Shorten the time of a single scan: Prioritize small-area high-definition scanning (such as 5× 5mm instead of 12× 12mm) and complete large-area imaging in different regions.

Anesthesia or sedation: In animal experiments or pediatric examinations, surface anesthesia (such as in ophthalmology) or mild sedation may be used when necessary.

(2) Scanning strategy

Repeated scanning: Collect multiple sets of data from the same area and improve the signal-to-noise ratio through software fusion.

Orthogonal scanning: Scan the same area from a vertical direction (such as horizontal + vertical) to cross-verify the influence of motion.

(3) Real-time feedback

Operator monitoring: Observe real-time images during the scanning process. If motion artifacts are detected, immediately pause and re-scan.

Patient cooperation prompt: Guide the patient to remain stable through the gaze light or voice prompt (such as “Please gaze at the green light flashing”).



4. Solutions for special scenarios

Cardiovascular OCT (IVOCT)

Trigger the scan synchronously with the electrocardiogram (ECG), avoiding the cardiac pulsation period (collection during the diastolic period).

Use rapid withdrawal catheters (such as 20 mm/s) to reduce the impact of vascular displacement.

Intraoperative OCT

Combine the navigation system (such as neurosurgical robots) to update the scanning position in real time.

Non-contact probes are adopted to avoid interference from instruments.

The absorption characteristics of hemoglobin: Deoxyhemoglobin in veins has a higher absorption rate for near-infrared light of specific wavelengths (typically 700-900nm) than that in surrounding tissues.

Reflection difference imaging: The device emits near-infrared light onto the skin, and the camera captures the reflection signal. Through algorithms, the veins are contrasted and enhanced with the surrounding tissues to form a clear image.

Multispectral imaging (optional technology)

Some high-end devices combine visible light and near-infrared light and adapt to different skin tones (such as patients with dark skin) through multispectral analysis.

AI image processing

Edge enhancement algorithm: Highlighting vein contours and reducing noise interference.

Depth prediction: Estimate the depth of veins through reflection intensity to assist in locating deep veins.



Ii. Enhanced Features of Desktop Design

Stable projection system

Fixed projector: Avoid the shaking of  handheld devices Vein Finder and precisely project vein images onto the skin surface (such as green/red contours).

Adjustable stand: Freely adjust the height and Angle to fit different parts such as the arm, back of the hand, and foot.

High-precision camera

Equipped with high-resolution sensors, it captures subtle vascular signals in real time and, in combination with the optical zoom function, magnifies local areas.

Environmental adaptability

Automatic calibration: Dynamically optimize imaging parameters based on ambient light and skin color.

Anti-interference design: Reduce the influence of surgical lamps or other light sources on imaging.



Iii. Work Process (Taking Blood Drawing as an Example)

Step 1: Patient localization

The patient placed his arm flat under the device and kept it stable.

Step 2: Quick scan

The device emits near-infrared light, generating a vein distribution map within 1-2 seconds and projecting it in real time.

Step 3: Vascular selection

Medical staff select the best puncture site (such as thick, straight, and unbifurcated veins) through screen or projection markers.

Step 4: Precise puncture

Puncture is completed under the guidance of venous projection, reducing the number of blind explorations.
