Half of image quality is the algorithm
Same panel, same exposure — a different processing algorithm puts the image in a different class. The iPet imaging algorithms are written in-house, specifically for canine and feline radiography: from a 2 kg cat to a 60 kg giant-breed dog, one parameter set delivers the image.

Image quality
Canine and feline studies deserve better than human-medicine algorithms
Human radiology deals with patients of similar size in standardised positions. Veterinary radiology does not — the same system images a 2 kg cat today and a 60 kg giant breed tomorrow, and on a single canine lateral thorax the penetration across lung field and spine differs by an order of magnitude. Stretch that with one fixed curve and either the lungs disappear or the bone burns out white. Our algorithms were rewritten from that starting point.
Multi-scale
Caravaggio 3.0 multi-scale enhancement
The image is decomposed into multiple scales and processed per scale: large scales compress thickness differences so thorax and abdomen read on one screen; small scales pull out trabecular bone and lung texture while noise is suppressed per scale — detail comes up without the noise coming with it.
Per-panel
Per-panel tone anchoring
Every detector model has its own response curve; generic parameters are always off. We calibrate per panel model: bone density and thin soft tissue are each anchored to a target grey level, so changing panels needs no re-tuning. The panel identity travels with the image — copy a case to another workstation and the processing result stays identical.
Anti-grid
Anti-scatter grid line suppression
Grid studies often carry a fine line pattern. The algorithm locates the grid peaks in the frequency spectrum and removes them point by point, second harmonics included. If no grid pattern is found, the image is returned untouched, pixel for pixel — better no processing than invented changes to image data.
Windowing demo
Why the same study can show different things
On the right is a real radiology step-wedge phantom — a row of aluminium steps of increasing thickness. Drag to change the display window: the narrower the window, the better tissues of similar density separate; open it too wide and everything turns to grey mush. Windowing is the first step of reading a study — and iPet computes the window width and level automatically for every processed image, so the clinician does not have to drag each one by hand.

Steps resolvable — / 12
Algorithms are not "tuned and done". Every change is re-run offline against the same corpus of real raw acquisitions and compared study by study; a version ships only when not a single image got worse — including the hard criterion that an unchanged pipeline must reproduce the previous version pixel for pixel.
Daily use
Six steps, one application
Registration, positioning, exposure, processing, measurement, and reporting all happen on the same workstation — each step's output feeds the next. Every vendor claims a workflow; ours is simply made to run smoothly.
01
Register
Enter patient and owner details; picking a body region expands its views, each card carrying its positioning diagram and exposure preset. Shoot-first, register-later is also supported.
02
Position
While waiting for exposure, the main display shows the standard positioning diagram — 105 canine and feline views are built in, and the selected view is the one displayed.
03
Expose
kVp / mA / ms / mAs are set automatically by species, body weight, and view. If parameter download fails, exposure is blocked — no image is ever taken on stale parameters.
04
Process
The raw image appears first for positioning check; enhancement runs on a background thread with visible progress, then window width and level are computed and applied automatically.
05
Measure
16 veterinary measurements with step-by-step guidance, results with reference ranges; anatomically impossible values are flagged invalid and never drawn onto the image.
06
Report
Templates and standard phrases, an optional AI draft of the findings; the veterinarian verifies line by line before sign-off, and key actions are written to the audit log.
Interface
Not renderings — the software as it is
The three screenshots below are taken from a running system. The interface is dark by design: reading rooms are dim, and a bright interface both glares and skews greyscale judgement. Functions sit directly on the page, not buried in nested menus.
Screenshots are from a development validation system with pet and owner names blurred; the interface is shown in Simplified Chinese here and ships in 8 languages, English included.
Storage & reading · three products, one chain
After the exposure: where images live, who can see them, and where
An image starts earning its keep after it is taken — and that is where many hospitals get stuck: studies live only on the acquisition PC, clinicians cannot see them in the consult room, referrals travel by USB stick, and owners photograph the screen. We built the whole chain — and all three products are ours, so no third party has to cooperate on the interfaces.
01 / Acquisition
iPet Workstation
The machine in the imaging room. Every study is generated to the DICOM standard, archived locally, and pushed to the in-hospital server automatically.
- Standard DICOM read/write — compatible with any conformant PACS
- C-STORE send / C-FIND query / C-ECHO connectivity test
- All network operations on background threads — the UI never freezes mid-send
- Works offline: studies archive locally and forward when the network returns
02 / In-hospital storage
iPet Imaging Server
Installed on the hospital's own server, receiving studies from every modality in the building. Data never leaves the hospital — any PC in the consult room, ultrasound room, or director's office reads studies in a browser.
- DR / ultrasound / CT / MRI, any brand
- Browser-based reading, zero client install
- Window width/level, zoom and rotate, multi-series compare, tag view
- Veterinary measurement wizard with breed reference values, written into the report
- Rechecks auto-compare prior measurements and plot the trend
- Automatic nightly backup, 14 rotating copies by default
03 / Cloud collaboration
Pengine AI Cloud Platform
For reading across branches and locations. Once studies are in the cloud, practice management, medical records, prescriptions, billing, and imaging run in one connected system.
- Standard DICOMweb interface, studies open directly in the browser
- Worklist / MPPS — modalities pull exam orders directly
- MPR multi-planar reconstruction and 3D volume rendering
- Hanging protocols — favourite layouts open in one click
- Imaging linked with EMR, prescriptions, and billing
- Multi-tenant architecture for chains and groups, managed per branch
The three tiers can be bought separately or singly. Any DICOM-conformant device can push studies — enter server address, port, and AE title. Nothing is locked to our own systems.
Signature tools
What a human-medicine PACS cannot measure, this one can
Cardiac scoring, hip evaluation, osteotomy planning — the metrics canine and feline clinicians actually use, and which human-medicine software simply does not have. All built in; no plug-ins to buy.
Guided
Multi-point measurements with a step wizard
For measurements needing seven or eight landmarks — VHS, PennHIP, TPLO — the wizard shows which point to place next and which anatomical landmark it is. No memorising sequences.
Referenced
Results with species reference ranges
Each value comes with the normal range for the species — VHS canine 8.5–10.5, feline 7.0–8.0 — no digging through the literature to compare.
Guarded
Impossible values are rejected
If mis-placed landmarks produce an anatomically impossible result, the software flags it invalid and explains the correct placement — a misleading number is never drawn onto the image.

General geometry
For true millimetre output, run a one-time distance calibration: draw a line of known length on the image and enter the real dimension. Ratio metrics such as VHS need no pixel spacing — a reference vertebra is calibrated per the standard method.
AI-assisted analysis
Writing the report is where most of the time goes
Veterinarians do not lack reading skill; they lack the time to turn what they see into a structured report. That is where the AI earns its place: it writes a first draft in the standard structure, and editing a draft is far faster than starting from a blank page.
Workstation
One-click report draft
The current study, together with species, region, and clinical notes, goes to the iPet AI reading model, which returns a draft in a two-part "Findings / Impression" structure. The model is explicitly constrained: state uncertainty as uncertainty, never invent measurement values, never prescribe treatment.
Cloud
AI reading + cross-validation
The cloud platform analyses uploaded studies and cross-checks the AI's output against six rule classes — species mismatch, sex conflict, age conflict, disease blacklist, wrong body region, internal consistency. Flagged passages are marked with red or amber warning bars — telling the clinician exactly where the AI may be wrong.
Closed loop
Clinician feedback is collected
Clinicians can rate every AI reading, and the system aggregates the ratings into accuracy statistics. The longer it runs, the clearer it becomes where the AI can be trusted — and where it cannot.

What's new in 2.0
Ten releases in a month — installed hospitals receive them automatically
From 1.0 to 2.0.2, the capabilities below shipped in the last two months and are running in hospitals now. All updates arrive through in-app automatic upgrade, with patient data and settings preserved as they are.
AI QC
Image-quality self-check + auto-tuning loop
Every acquisition passes an AI quality check first: exposure adequate, positioning correct, motion artefact present or not — failures come with the reason. Processing parameters fine-tune themselves against per-region baselines: the more you shoot, the closer they get.
Layering
Tissue layering and pseudo-colour display
Bone and soft tissue emphasised in separate layers, with a one-click pseudo-colour mode for soft-tissue density differences — layers the eye cannot separate in thorax or abdomen, colour separates for you.
Rescue
Underexposure rescue and collimator-frame detection
Severely underexposed studies are auto-windowed for rescue so a retake is often unnecessary; the collimator's lead frame is detected automatically so it no longer pollutes the histogram and bone is not dragged to white.
DICOM
Worklist / Q-R / SCP / MPPS — the full six
Pull filtered worklists from the practice system, query and retrieve priors, receive outside studies, report MPPS and storage commitment; RDSR dose reports sent on demand.
Compare
Prior-study comparison reading
A patient's prior studies open side by side automatically, with zoom and windowing linked. Fracture healing and post-operative rechecks no longer mean flipping between two windows.
Delivery
Owner delivery package
USB or disc exports carry a no-install viewer, or generate a QR-code link — owners and referral hospitals read studies without installing anything.
Safety
Backup & restore · login lockout · de-identification
Daily automatic backup of database, settings, and image increments with one-click restore; password rules and lockout on repeated failures; DICOM exports can strip owner and patient identity for external consults or publication.
Dose · Fault
Dose ledger and fault guidance
Every exposure's radiation dose is logged automatically, exportable as a safety report at any time; on a device error, the software presents the handling steps and can report to an IWA engineer in one click.
Output · i18n
DICOM print, image stitching, 8 languages
Film printing over the DICOM standard; long-bone and spine series stitch into full-length images; the interface ships in 8 languages including English, with remote assistance built in.
The version number is at the bottom right of the software. Hospitals on 1.0.x are prompted to upgrade to 2.0 automatically — the whole path needs no reinstall and no panel re-calibration.
