Ichvolume Calculator
Estimate your ichvolume with our free cardiovascular system calculator. See reference ranges, risk factors, and next-step guidance.
Formula
Volume = (A x B x C) / 2
Where A = longest hemorrhage diameter on the CT slice with the largest area of hemorrhage, B = longest diameter perpendicular to A on the same slice, and C = approximate depth calculated by multiplying slice thickness by the number of slices with hemorrhage. All measurements are in centimeters, yielding volume in cubic centimeters (mL).
Worked Examples
Example 1: Moderate Basal Ganglia Hemorrhage
Problem: A 65-year-old patient presents with a left basal ganglia hemorrhage. CT scan measurements show A = 5 cm, B = 4 cm, C = 3 cm. Calculate the hematoma volume.
Solution: Using the ABC/2 formula:\nVolume = (A x B x C) / 2\nVolume = (5 x 4 x 3) / 2\nVolume = 60 / 2\nVolume = 30 mL\n\nThis falls at the threshold between moderate and moderate-large hemorrhage categories.
Result: ICH Volume: 30 mL | Category: Moderate | 30-day Mortality Risk: 20-50%
Example 2: Small Lobar Hemorrhage
Problem: A 72-year-old patient has a right frontal lobar hemorrhage. CT measurements: A = 3 cm, B = 2.5 cm, C = 2 cm. Determine volume and prognosis.
Solution: Using the ABC/2 formula:\nVolume = (A x B x C) / 2\nVolume = (3 x 2.5 x 2) / 2\nVolume = 15 / 2\nVolume = 7.5 mL\n\nThis is classified as a small hemorrhage with generally favorable prognosis.
Result: ICH Volume: 7.5 mL | Category: Small | 30-day Mortality Risk: < 20%
Frequently Asked Questions
How accurate are the results from Ichvolume Calculator?
All calculations use established mathematical formulas and are performed with high-precision arithmetic. Results are accurate to the precision shown. For critical decisions in finance, medicine, or engineering, always verify results with a qualified professional.
How do I get the most accurate result?
Enter values as precisely as possible using the correct units for each field. Check that you have selected the right unit (e.g. kilograms vs pounds, meters vs feet) before calculating. Rounding inputs early can reduce output precision.
How do I interpret the result?
Results are displayed with a label and unit to help you understand the output. Many calculators include a short explanation or classification below the result (for example, a BMI category or risk level). Refer to the worked examples section on this page for real-world context.
Does Ichvolume Calculator work offline?
Once the page is loaded, the calculation logic runs entirely in your browser. If you have already opened the page, most calculators will continue to work even if your internet connection is lost, since no server requests are needed for computation.
Can I share or bookmark my calculation?
You can bookmark the calculator page in your browser. Many calculators also display a shareable result summary you can copy. The page URL stays the same so returning to it will bring you back to the same tool.
Is Ichvolume Calculator free to use?
Yes, completely free with no sign-up required. All calculators on NovaCalculator are free to use without registration, subscription, or payment.
