Diagnostic imaging is recognized as an important adjunct to clinical examination in the care of patients with many common illnesses. Most such imaging will be by radiography or ultrasound. In pursuit of the World Health Organization's goal of health for all, many of the examinations will be performed at the first referral level, where patients will be seen, referred from primary care or in need of emergency treatment. Many countries do not have sufficient radiologist or sonologists to provide skilled techniques and interpretation, and imaging may be requested, interpreted and often performed by medical officers with little or no specialist training or experience.

This training is to provide guidance on the use of diagnostic imaging by non-specialists. The use of ultrasound is increasing rapidly worldwide; it is particularly important in obstetrics, but also provides useful information about the abdomen and soft tissues. Because there is no ionizing radiation, ultrasound should be the preferred method of imaging whenever it can give useful clinical information.

The training is basic to help with technique, recognition of the normal, and differential diagnosis. It indicates the clinical situations in which ultrasound scanning is likely to provide guidance for the care of the patient, and those in which scanning will not be reliable or helpful. The decision to scan is based on many factors and each individual patient's needs must be taken into account.

The safety of ultrasound has been a subject of considerable discussion and study. After three decades of use and the examination of thousands, probably millions, of people, the question of absolute safety is still being debated. The potential risks, if any, also need to be weighed against the benefits, particularly in obstetrics, where ultrasound provides much information that cannot be obtained in any other way. That's why the ultrasound has evolved as first choice of imaging technique now a days.

Ultrasound is very operator-dependent. Proper training and experience are required in making an accurate diagnosis from ultrasound images. The WHO scientific group concluded that a doctor needs at least one month's full-time training in a busy ultrasound department to achieve a minimum level of expertise. This would amount at least 200 obstetric and abdominal examinations made under supervision.

But in the present day scenario of busy and hectic practice schedule many doctors are not in a position to undergo training such a lengthy training at one stretch. So keeping those busy practitioners in view the training schedule is designed in flexible modules so that each doctor can come and get trained at his own convenience and time. There is no time constrain . He can come at any time and join the course. He can choose either the crash course or regular course. He can attend the CME programs at no additional cost.

The training also provides guidance on the standards by which ultrasound equipment may be judged. There are many varieties of such equipment. The general purpose ultrasound scanner as its name implies should be suitable for all general purpose studies at any level of medical care obstetrics, abdominal and soft tissues;  will only be bettered by much more expensive ultrasound units.
