Welcome to SonoBuddy: Your Pocket Ultrasound Reference
Introducing SonoBuddy — the fast reference tool built specifically for sonographers. Instant access to everything you need mid-scan, right in your pocket.
Whether you're a new grad walking into your first solo scan or an experienced sonographer who wants a faster reference than flipping through a textbook, SonoBuddy was built for you.
What Is SonoBuddy?
SonoBuddy is a Progressive Web App (PWA) designed to give sonographers instant, phone-in-pocket access to the clinical information they need — right in the scan room.
No account required. No subscription wall. No loading spinner. Just open it and go.
What's Inside
Measurement Tables
Normal and abnormal reference values for:
- Vascular — carotid IMT, aorta, IVC, portal vein, renal artery doppler
- Abdominal — liver, spleen, kidneys, gallbladder, pancreas
- OB/GYN — uterus, ovaries, follicles, fetal biometry
- Thyroid — gland dimensions, nodule size thresholds
- Cardiac — basic echo measurements
Every measurement includes a clinical note so you understand why the threshold matters, not just what the number is.
Exam Protocols
Step-by-step scanning guides with probe selection tips, key images to capture for PACS, and a full report checklist. Protocols currently include:
- Carotid duplex
- Lower extremity venous DVT survey
- Abdominal aorta
- Renal artery doppler
- Abdominal complete
- OB first trimester
Clinical Calculators
Built-in calculators that return instant, color-coded results:
- ABI (Ankle-Brachial Index) with PAD severity grading
- Resistive Index with renal interpretation
- Carotid Stenosis grading (SRU 2003 criteria)
- Organ Volume (ellipsoid formula)
- AFI (Amniotic Fluid Index)
- Gestational Age & EDD from LMP or CRL
- Thyroid Volume
Pathology Library
Concise cards for the most common pathologies you'll encounter — ultrasound findings, red flags, differentials, and practical reporting tips.
Why We Built It
New sonography graduates told us the same thing over and over: "I keep a stack of papers in my pocket because I can't find anything fast enough mid-scan."
Existing apps either cost money, require an account, or are built for physicians rather than the person holding the probe. SonoBuddy is purpose-built for sonographers, with a UI designed for one-handed use in a darkened scan room.
What's Next
SonoBuddy is actively being developed. Coming soon:
- More protocols (OB anatomy survey, penile duplex, portal hypertension workup)
- Expanded pathology library with annotated images
- Favorites — pin the measurements and protocols you use every day
- Enhanced offline mode
SonoBuddy is a reference tool, not a diagnostic authority. All clinical decisions should involve the ordering provider and interpreting physician.
