9.4 Urology Measurement Operations
Tips: 1. See the table in "9.3 Urology Measurement Tools" above for measurement tools
and methods.
2. For the definitions of measurement, calculation and study, refer to "1.3
Measurement, Calculation and Study".
3. The order of the measurement items is presettable, see "2.4.2 Application
Measurement Preset" for details.
4. A measurement tool can be activated by clicking the item either in the
measurement menu or touch screen menu; it is described as "Select/Click ...
(certain item) in the measurement menu" in the following procedures.
9.4.1 Measurement Tool Operations
Operations of all Urology measurement tools are the same as Distance measurement of 2D
General Measurements.
The measurement procedures are as follows taking Prostate L measurement as an example:
1. Select [Prostate L] in the measurement menu.
2. Use the Distance of 2D General Measurements to measure Prostate L.
9.4.2 Calculation Tool Operations
Renal Vol
Function: measures Renal L, Renal H and Renal W, calculates Renal Vol.
NOTE: Need to be measured in left and right side respectively.
1. Select [Renal Vol] in the measurement menu.
2. Use the method of Distance measurement of 2D General Measurements to measure Renal L,
Renal H and Renal W. The Renal Vol is calculated automatically.
Prostate Vol
Function: measures Prostate L, Prostate H and Prostate W, calculates Prostate Vol and PPSA. If
[Serum PSA] in [Patient Info] -> [URO] has been input, PSAD (Prostate Special Antigen Density)
will also be calculated.
PPSA (ng/ml) = PPSA Coefficient (ng/ml
2
) × Prostate Vol (ml)
PSAD (ng/ml
2
) = Serum PSA (ng/ml) / Prostate Vol (ml)
Here, PPSA Coefficient and Serum PSA are input in [Patient Info] -> [URO] dialog box. The default
value of PPSA Coefficient is 0.12.
1. Select [Prostate Vol] in the measurement menu.
2. Use the Distance method in 2D General Measurements to measure Prostate L, Prostate H
and Prostate W.
The system calculates Prostate Vol and PPSA.
The PSAD displays in the report if the PSA value is input.
Testis Vol
Function: measures Testis L, Tes ti s H a nd Tes tis W, calculates Testis Vol.
