Among the present day CT scanners, Spiral CT is one of the latest technologies for the best patient care. This can image entire anatomic regions like the lungs in a quick 20 to 30 seconds time. Instead of acquiring a stack of individual slices, which may be misaligned due to slight patient motion or breathing in between each slice acquisition, spiral CT acquires a volume of data with the patient anatomy all in one position.The CT scanner installed in this hospital is Siemens Somatom Esprit model which gives good resolution in short period of time.
