Instrument Uses
Ultrasonography machine uses ultrasound to produce images from within the body; vide link
X-ray uses X-rays to produce images of structures within the body; vide link
Contrast media for X-rays to provide a high contrast image of the details of the viscera under study; eg. salts of heavy metals, gas like air, radio-opaque dyes, organic iodides, etc
Echocardiography machine sonography of the heart is done here top know its function and state
Computer axial tomography scan (CT Scan)/(CAT Scan) to visualize the interior of the body in slices (traditionally showing horizontal slices); vide link
Magnetic resonance imaging (MRI) alias Nuclear magnetic resonance {NMR) High strength ( .15 to 1.5 Tesla)[4] are used to excite protons that produce the record results (like CT scan). It can show particular tissues more clearly than CT.[5]; vide link
Linear Accelerator used in Radiotherapy for cancer
Functional magnetic resonance imaging (fMRI) vide link
Positron emission tomography (PET Scan) vide link
Radio-isotope scan or Nuclear scintigraphy These radioactive compounds are administered so that specific tissues take them up. The amount and anatomical detail of the uptake produces the scan result.
SPECT Scan vide link
Interventional radiology minimally invasive surgeries under radiological imaging, eg. angioplasty, TIPS.
Brachytherapy apparatus vide link
