Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry results.
X-ray: uses X-rays to produce images of structures within the body; video link: Contrast media for X-rays: to provide a high contrast image of the details of the viscera under study; e.g. salts of heavy metals, gas like air, radio-opaque dyes, organic iodides, etc. Echocardiography machine: sonography of the heart is done here to know its ...
The Risser sign is an indirect measure of skeletal maturity, whereby the degree of ossification of the iliac apophysis by x-ray evaluation is used to judge overall skeletal development. Mineralization of the iliac apophyses begins at the anterolateral crest and progresses medially towards the spine.

X-ray of the hips of a 40-year-old female, with dysplasia of her right hip. In the adult hip there are important landmarks to be recognized on plain film radiographs: [ 3 ] The iliopectineal or iliopubic line is formed by the arcuate line of the ilium and the superior border of the superior pubic ramus up to the pubic symphysis.
HSG test to know the blockage of the fallopian tubes. Hysterosalpingography (HSG), also known as uterosalpingography, [1] is a radiologic procedure to investigate the shape of the uterine cavity and the shape and patency of the fallopian tubes. It is a special x-ray procedure using dye to look at the womb and fallopian tubes. [2]
The DQE is generally expressed in terms of Fourier-based spatial frequencies as: [10] = = ()where u is the spatial frequency variable in cycles per millimeter, q is the density of incident x-ray quanta in quanta per square millimeter, G is the system gain relating q to the output signal for a linear and offset-corrected detector, T(u) is the system modulation transfer function, and W(u) is the ...
X-ray Markers, also known as: anatomical side markers, [1] Pb markers, lead markers, x-ray lead markers, or radiographic film identification markers, are used to mark x-ray films, both in hospitals and in industrial workplaces (such as on aeroplane parts and motors). They are used on radiographic images to determine anatomical side of body ...
