Automated ultrasound measurements

Your ultrasound machine already calculates far more than ends up in the report. NewVision reads the measurements the device produces — through DICOM Structured Report — and places every one of them into the report with reference values, percentiles and graphs. Nothing is dictated, nothing is retyped, and the measurements clinicians normally skip because typing them is not worth the time are captured too.

Why manual measurement entry is the weak point

In the usual arrangement, the clinician reads values aloud and an assistant types them into a computer. Three things follow from that.

• Values get mistyped. A transposed digit in a biometry value changes a percentile, and nothing in the workflow catches it.
• Most measurements are never recorded. Only the handful considered essential get dictated; the rest exist on the device for a few minutes and then disappear.
• The data cannot be reused. Values typed as free text into a document cannot be plotted against a growth curve or compared with the previous scan.

NewVision transfers all measurements and their reference values with zero transcription error, because the number in the report is the number the machine calculated.

How the transfer works

1. Worklist first. Patient demographics are pushed to the ultrasound device from the worklist, so the study is already bound to the right patient before the first caliper is placed.
2. The clinician scans normally. Measurements are taken on the machine using its own packages — no change in scanning technique, no second keyboard.
3. The device sends a Structured Report. At end of exam the machine transmits images, clips and an SR object containing the measurement set to the NewVision DICOM Server.
4. NewVision parses the SR. Each coded measurement is mapped to a named report field, stored in normalised form rather than as text.
5. Reference data is applied. Values are compared against reference tables and plotted where a curve applies, so the report shows position, not just a number.
6. The report is assembled. Measurement tables, graphs and selected images are laid into the specialty template, ready for review and sign-off.

Because values are stored in normalised standard form rather than inside a document, the same data supports serial comparison across visits and department-level analysis later.

Measurement coverage by specialty

The lists below are the measurement fields the report templates are built around. Values populate automatically when the device transmits them in its Structured Report; anything the device does not send can still be measured, drawn or annotated manually inside NewVision.

Reference tables and graphs

A measurement without context asks the reader to remember normal ranges. Because NewVision stores values in standard form, it can plot them:

• Fetal biometry parameters plotted against reference growth curves, with percentile per parameter.
• Serial plots across visits, so interval growth is visible rather than inferred from two separate printouts.
• Adult measurements compared against normal ranges in the measurement table, flagged when outside range.
• Reference tables configurable, since departments differ on which published references they use.

What happens when the device sends nothing

Situation	How it is handled
Device supports SR but it is switched off	Enabled in the machine’s DICOM configuration — the most common fix, and it costs nothing
Device sends images only	Measurements are made on the transferred images inside NewVision, with drawings and annotations saved to the study
Measurement not in the device’s package	Entered as a manual field in the template; it still becomes normalised, comparable data
Unusual or proprietary coding	Mapped during commissioning against a real SR sample from your machine
