摘要：
An apparatus (10) for measuring a labor progress parameter during childbirth, help with ultrasonic deimágenes obtained by ultrasonic pulses, said apparatus (10) comprising: an ultrasonic probe a fixing means for fixing said ultrasound probe (1) in the body of a parturient (2) so that dichasonda (1) has a visual field (7) comprising a body of said parturient (2) and a fetus (3), in particular the endocervical canal (8) or the pubis parturient (2) a control unit (13) for receiving and analyzing signals from said ultrasonic probe (1), as decontrol unit (13) creates or receives as input of said probe to a reference ultrasound image (11) and several subsequent imágenesultrasónicas (12) , taken successively after said reference ultrasound image (11) a user interface (14) to select an area of interest (21) in said reference ultrasound image (11) by an operator, the user interface being (14 ) adapted to select said region of interest (21) essentially centered around said body of the parturient, said region of interest (21) comprising a plurality pixels (23) which control unit (13) comprising: means for automatic tracking in order to follow said region of interest (21), automatic means deseguimiento being said designed to identify areas derived interest (22) in the pictures chosen from lasvarias ultrasound images subsequent (12), said zones derived interest (22) of said deinterés area (21) selected in said reference ultrasound image (11), said tracking means comprising: means for calculating a function of predetermined local pixel for each pixel (23) or group of pixels of interest dichazona (21) in said reference ultrasound image (11) and in each selected from said subsequent ultrasound variasimágenes (12) image means for calculating iteratively, from said reference ultrasound image (11), the position dedicha derived region of interest (22) in each selected image, said means for iterative calculation designed paraefectuar comparisons being between: values of said local p
