Abstract
According to the bladder volume measuring device according to the present invention, it is possible to more accurately measure the amount of urine contained in the bladder by calculating the bladder volume according to the first straight line and the second straight line crossing the inside of the bladder region included in the cross-sectional image including the bladder.
Claims8
A bladder volume measuring device, comprising:
- an ultrasound transducer that transmits an ultrasound transmission signal to a human bladder and receives an ultrasound reception signal reflected from the bladder;
- a processor configured to generate a cross-sectional image including the bladder based on the ultrasound reception signal;
- and
- a processor configured to calculate a bladder volume according to a first straight line and a second straight line crossing an inside of a bladder region included in the cross-sectional image, wherein the processor configured to calculate the bladder volume includes a lookup table that determines the bladder volume according to a product of a first straight line length corresponding to a length of the first straight line and a second straight line length corresponding to a length of the second straight line;
- and
- wherein the lookup table includes a plurality of sub lookup tables determined according to the product of the first straight line length and the second straight line length, and each of the plurality of sub lookup tables has a different slope corresponding to a ratio at which the bladder volume linearly increases as the product of the first straight line length and the second straight line length increases.
