The achievement of getting a diagnosis or findings that helps pointing towards a diagnosis is unbridled.\r\n\r\nIn this small chapter we'll bring you step by step on how to prepare you and the patient for your first ever ultrasound scan.\r\n\r\n \r\n\r\nSetting up the patient<\/strong>\r\n\r\nA patient should always be at the most comfortable position possible when undergoing an ultrasound scan. Preferably the patient should be at a semi-recumbent position at 45 degree angle and be approached from the right side as in any physical examination.\r\n\r\n \r\n\r\n \r\n\r\n[caption id=\"attachment_46\" align=\"aligncenter\" width=\"1024\"]\"Patient Preferred patient position during ultrasound scan.

It will give a good stability and also grip on the ultrasound probe, as well as the needed coordination when moving and manipulating a probe.\r\n\r\nStabilisation of the probe during scanning can be achieved by leaning your heel of hand or your 5th finger onto the patient's body. This will allow you to make minute movements in order to attain best window for your scan.\r\n\r\nAdequate amount of gel is needed to assist in moving the transducer along any specific planes and also to optimize the window and quality of image. This is because the gel will become the medium between the transducer and the tissue or surface being scanned, making sure that the ultrasound waves being reflected will not dissipate, which will decrease the quality of image.\r\n
