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]
With rotating envelope tubes, the entire vacuum tube rotates with respect to the anode axis, versus rotating anode tubes, in which the target disk rotates inside a stationary vacuum tube. The target cools by conduction rather than radiation. Heat storage is less important, and waiting times are eliminated. [1]
Electron tomography (ET) is a tomography technique for obtaining detailed 3D structures [1] of sub-cellular, macro-molecular, or materials specimens. Electron tomography is an extension of traditional transmission electron microscopy and uses a transmission electron microscope to collect the data.
Solid-anode microfocus X-ray tubes are in principle very similar to the Coolidge tube, but with the important distinction that care has been taken to be able to focus the electron beam into a very small spot on the anode. Many microfocus X-ray sources operate with focus spots in the range 5-20 μm, but in the extreme cases spots smaller than 1 ...
Graded intensity across the beam, generally a drawback, can be turned to advantage in some techniques by positioning the object or patient relative to the X-ray tube. For example, when imaging a foot , which is thicker at the ankle end than the toes, the toes should be positioned toward the anode and the ankle toward the cathode. [ 6 ]
Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...

The standard abdominal X-ray protocol is usually a single anteroposterior projection in supine position. [3] Special projections include a PA prone, lateral decubitus, upright AP, and lateral cross-table (with the patient supine).
