The A-mode ultrasonography is especially qualified for measuring tissue thickness. By using high frequencies (8--10 MHz) upper layers can be measured with an accuracy of approximately 0.15 mm. This accuracy in measurement is required in connexion with optimization of dose during therapy of urinary bladder tumors by way of the Neodymium-YAG laser. The newly developed 8 MHz-endo-transducer makes possible intravesical measurement of bladder-wall thickness under cystoscopoic view. This method presents itself as a new opportunity for staging urinary bladder tumors.
