Find the window. Follow the pleura. Read the pattern.
Arrow keys slide · Q/E rotate · W/S fan · A/D rock
Animated reference windows · marker left = cranial · compare the complete sampled exam
Lung preset · harmonics off · indicator on screen left
Parasagittal plane · marker cranial
Indicator → head · shown on screen left.
Explore: select a zone, drag the probe in its local rib window, and rotate or tilt. Change the case to compare patterns. The same model drives the image and acquisition checks.
Phenotypes: compare six animated windows for each of the five canonical lung POCUS phenotypes and review the differential. Inadequate image quality is a separate outcome. Select a tile to enlarge it.
Hemidiaphragm dysfunction: in Explore, choose the right or left case. The affected organ and dome are elevated, with paradoxical cranial movement during the inspiration cue. Compare the opposite base. Screen left is cranial at the reference orientation. This illustrative pattern does not cover every form of diaphragm dysfunction.
Acquire: move to the requested window and optimize the normal view. Store after watching one full breath. Hints cap the score at two stars. These are draft simulator scores, not clinical competency measures.
Read: interpret ten animated clips. Probe settings and case names are hidden until the answer is submitted. One answer counts per clip.
Controls: arrows slide; Q/E rotate; W/S fan; A/D rock; F freezes; L toggles labels. Keyboard shortcuts supplement every clickable control.
Phone probe: open Phone probe above the body map and enter the code (or scan the QR) on a phone at this site’s probe.html. Lay the phone flat, screen up, top edge toward this screen; its amber right edge is the indicator. Tilting fans, turning rotates, heeling sideways rocks, and dragging a finger on its screen slides. The probe starts flat with the indicator toward the patient’s left; switching windows or tapping Zero re-centres. Both devices need internet; on the same Wi-Fi the link becomes direct. Nothing personal is sent.
Image detail: while the probe moves the image is drawn quickly; once it is still, it is quietly redrawn at 2× and then 4× density. Detail on the bezel sets Auto (the sharpest your machine keeps smooth), High (2×), Max (4×, may slow the animation) or Off. Scores use the standard image and are unaffected.
Scope: six supine adult windows, schematic motion and artifacts. M-mode samples the center B-mode column; it is optional and does not independently diagnose pneumothorax. Central disease and sites outside the six windows may be missed.

Start with the phone lying FLAT, screen up — bottom edge toward you, top edge pointing at this screen. The amber mark on its right edge is the probe indicator. Tilting fans, turning it rotates, heeling it sideways rocks, and dragging a finger on its screen slides. Both devices need an internet connection; nothing personal is sent.
On the phone, scan the code or open this site/probe.html and enter:

Tilt, twist and heel the phone to aim the plane; drag on its screen to slide. Tap Zero on the phone (lying flat, top edge toward this screen) whenever you want to re-centre; switching windows re-centres automatically. The keyboard and on-screen controls still work.
