Patient-specific cardiac blood flow insights from standard CT imaging. CorASCT maps blood stagnation automatically — turning routine scans into a new clinical signal for stroke risk.

01 — Why it matters

A silent failure of cardiac blood flow.

Deviated flow in the left atrium drives thrombus formation — the dominant mechanism behind ischemic stroke. Today's risk scores miss the patient. The signal lives in the scan.

02 — The solution

Introducing CorASCT.
More than improved imaging.

Automated blood stagnation mapping from a standard CT — a new quantitative marker for clinicians, designed for cloud-native distribution through existing PACS platforms.

01
Patient-specific

Computes hemodynamics per case — no population averages, no proxies.

02
Standard CT input

Works with the cardiac CTs already acquired across cardiology and neurology workflows.

03
Cloud-native

Delivered as an automatic application, integrated into PACS and AI marketplaces.

03 — How it works

From scan to signal in four steps.

01
Standard CT acquired

A routine cardiac CT enters the imaging workflow — no new hardware, no new protocol.

02
Whole-heart segmentation

Seven cardiac structures identified at mean confidence 0.968 (v4.2.1).

03
Hemodynamic computation

Patient-specific blood flow and residence-time fields are computed (LBM, v3.1.0).

04
Clinical output

Stasis fraction, stagnant volume and PV/MV flow are returned to the radiologist's PACS view.

This is the actual segmentation.

Not a render. The model identifies seven cardiac structures from a routine CT — the same data that feeds the hemodynamic computation in step 03.

Where stasis matters.

The left atrium and left ventricle are the chambers where slow, recirculating blood drives thromboembolic risk. Cordicity quantifies stagnation here.

Right-side anatomy, isolated.

Right atrium and right ventricle are segmented with the same model — enabling full four-chamber flow analysis when needed.

Scene 04 · Outflow tracts
04 / 04

Inflow and outflow, quantified.

Aorta and pulmonary artery boundaries define the flux surfaces. PV inflow and MV outflow are computed directly from these — step 03 takes over from here.

04 — Use cases

Built for clinical impact
and scalable distribution.

Stroke risk
Quantitative stroke risk assessment

Augment CHA₂DS₂-VASc with patient-specific stagnation data — identify the silent high-risk patient.

Cardiology
Atrial fibrillation workup

Stratify AF patients beyond rhythm alone — guide anticoagulation and ablation priority decisions.

Triage
Clinical prioritisation

Route urgent cases to specialist review faster, with objective evidence from the scan.

NOAC
Decision support

Inform anticoagulation strategy with a flow-based marker that complements existing risk scores.

05 — Traction

Momentum across capital, clinic and channel.

Backed by leading Nordic investors, anchored at Linköping University, and progressing toward integrated distribution through the imaging platforms clinicians already use.
