S Series: Performing an Ultrasound Exam

00:01:49,229 "Do you want to continue?" 30 00:01:49,229 --> 00:01:50,562 by selecting OK. 31 00:01:53,400 --> 00:01:55,114 Once the patient is entered, 32 00:01:55,114 --> 00:01:58,798 all saved images are linked to that patient. 33 00:01:58,798 --> 00:02:02,013 Patient information can be edited during the exam 34 00:02:02,013 --> 00:02:04,606 by pressing the Patient key, 35 00:02:04,606 --> 00:02:08,543 however, if the patient name or ID number changes, 36 00:02:08,543 --> 00:02:11,298 a new patient is created. 37 00:02:11,298 --> 00:02:13,003 If you have not already done so, 38 00:02:13,003 --> 00:02:16,257 select the exam type from the secondary controls 39 00:02:16,257 --> 00:02:18,772 on the left of the image display. 40 00:02:18,772 --> 00:02:20,655 The exam choices available 41 00:02:20,655 --> 00:02:24,065 are dependent upon the connected transducer. 42 00:02:24,065 --> 00:02:27,683 Selecting the exam type will optimize the system settings 43 00:02:27,683 --> 00:02:30,899 for the clinical exam you have chosen. 44 00:02:30,899 --> 00:02:35,654 You may change the exam type at any time during this study. 45 00:02:35,654 --> 00:02:38,875 The exam type symbol will change in the top right corner 46 00:02:38,875 --> 00:02:40,966 or the image display to indicate 47 00:02:40,966 --> 00:02:44,164 the exam type has been selected. 48 00:02:44,164 --> 00:02:46,595 Use a coupling gel to remove any air 49 00:02:46,595 --> 00:02:50,839 between the transducer face and the skin surface. 50 00:02:50,839 --> 00:02:53,665 Once you have located the area of interest, 51 00:02:53,665 --> 00:02:57,771 adjust the depth of the image to center the area of interest 52 00:02:57,771 --> 00:03:00,730 in the middle of the image display. 53 00:03:00,730 --> 00:03:04,013 For quick optimization of the gain settings on the system, 54 00:03:04,013 --> 00:03:06,016 press the Auto Gain key. 55 00:03:06,016 --> 00:03:08,093 The system will evaluate the image 56 00:03:08,093 --> 00:03:11,963 and apply the appropriate gain level settings. 57 00:03:11,963 --> 00:03:14,565 If you would prefer to change the gain settings, 58 00:03:14,565 --> 00:03:16,832 turn the Gain knob to the Near, 59 00:03:16,832 --> 00:03:19,621 Far, or default Overall mode. 60 00:03:19,621 --> 00:03:22,447 This will increase or decrease the amount of gain 61 00:03:22,447 --> 00:03:27,281 applied to the Near field, Far field, or the Overall image. 62 00:03:27,281 --> 00:03:30,531 To toggle between gain compensation selections, 63 00:03:30,531 --> 00:03:32,985 press the Gain knob. 64 00:03:32,985 --> 00:03:35,177 Once the desired image is obtained, 65 00:03:35,177 --> 00:03:37,063 you may freeze the image. 66 00:03:37,063 --> 00:03:39,713 At this point, you may save the image, 67 00:03:39,713 --> 00:03:43,380 review individual frames in the cine buffer, 68 00:03:45,199 --> 00:03:46,449 zoom the image, 69 00:03:50,752 --> 00:03:52,502 or take measurements. 70 00:03:55,397 --> 00:03:59,362 The cine buffer can be accessed using the Gain knob. 71 00:03:59,362 --> 00:04:01,633 Turning the Gain knob counterclockwise 72 00:04:01,633 --> 00:04:04,309 reviews images retrospectively, 73 00:04:04,309 --> 00:04:06,484 and moving the Gain knob clockwise 74 00:04:06,484 --> 00:04:09,220 reviews images prospectively. 75 00:04:09,220 --> 00:04:11,546 The frame number will change dynamically 76 00:04:11,546 --> 00:04:14,691 as the Gain knob is manipulated. 77 00:04:14,691 --> 00:04:18,043 Press the Zoom key to activate the touch pad 78 00:04:18,043 --> 00:04:21,685 to pan the image to the area of interest. 79 00:04:21,685 --> 00:04:25,441 A measurement may be performed on a frozen image. 80 00:04:25,441 --> 00:04:29,229 Activate calipers by pressing the Caliper key. 81 00:04:29,229 --> 00:04:31,450 Move the caliper to the point of interest 82 00:04:31,450 --> 00:04:33,367 by using the touch pad. 83 00:04:34,239 --> 00:04:36,321 To measure from the skin surface, 84 00:04:36,321 --> 00:04:39,825 place the caliper at the area of interest. 85 00:04:39,825 --> 00:04:41,647 An active measurement will be displayed 86 00:04:41,647 --> 00:04:45,651 in the bottom left corner of the image display. 87 00:04:45,651 --> 00:04:47,844 To perform a linear measurement, 88 00:04:47,844 --> 00:04:50,206 place the caliper at the point of interest 89 00:04:50,206 --> 00:04:52,727 and press the Set key. 90 00:04:52,727 --> 00:04:55,489 Another caliper will be activated. 91 00:04:55,489 --> 00:04:57,567 Move the caliper to the point of interest 92 00:04:57,567 --> 00:04:59,900 to complete the measurement. 93 00:05:02,221 --> 00:05:03,961 Area measurements may be obtained 94 00:05:03,961 --> 00:05:06,294 by using the Ellipse Method. 95 00:05:15,048 --> 00:05:17,385 If further image optimization is needed 96 00:05:17,385 --> 00:05:19,836 based on the patient's body habitus, 97 00:05:19,836 --> 00:05:23,342 select the 2D Optimization feature on page two 98 00:05:23,342 --> 00:05:26,225 of the secondary controls. 99 00:05:26,225 --> 00:05:28,710 This feature automatically adjusts features 100 00:05:28,710 --> 00:05:32,877 such as focal zones, transducer frequency, and bandwidth. 101 00:05:34,232 --> 00:05:37,578 Res provides the best resolution possible. 102 00:05:37,578 --> 00:05:41,740 Gen provides a balance between resolution and penetration. 103 00:05:41,740 --> 00:05:45,547 Pen provides the best possible penetration. 104 00:05:45,547 --> 00:05:48,655 Color Doppler may be used to quickly identify 105 00:05:48,655 --> 00:05:51,803 where blood flow is located in a structure. 106 00:05:51,803 --> 00:05:54,865 Press the Color key to activate Color Doppler 107 00:05:54,865 --> 00:05:57,328 or Color Power Doppler. 108 00:05:57,328 --> 00:05:59,833 A region of interest or ROI box 109 00:05:59,833 --> 00:06:02,664 will appear in the center of the screen. 110 00:06:02,664 --> 00:06:06,831 Use the touch pad to change the position of the ROI box. 111 00:06:07,962 --> 00:06:10,413 The system settings for color will be displayed 112 00:06:10,413 --> 00:06:13,679 in the top left corner of the screen. 113 00:06:13,679 --> 00:06:17,059 Use the Gain knob to adjust the overall color gain level 114 00:06:17,059 --> 00:06:20,895 for Color Power Doppler or Color Doppler. 115 00:06:20,895 --> 00:06:22,838 When you freeze a color image, 116 00:06:22,838 --> 00:06:24,701 the Gain knob can also be used 117 00:06:24,701 --> 00:06:28,618 to review individual frames in the cine buffer. 118 00:06:29,978 --> 00:06:33,395 Press the 2D key to return to 2D imaging. 119 00:06:34,662 --> 00:06:36,568 When you are ready to store your image, 120 00:06:36,568 --> 00:06:39,229 press the Save key to save the image 121 00:06:39,229 --> 00:06:41,847 to the internal storage. 122 00:06:41,847 --> 00:06:45,797 The capacity of the internal storage is four gigabytes, 123 00:06:45,797 --> 00:06:48,380 or approximately 32,000 images. 124 00:06:49,644 --> 00:06:53,036 To save an image clip, press the Clip key. 125 00:06:53,036 --> 00:06:55,796 Clips are stored prospectively. 126 00:06:55,796 --> 00:06:59,359 The length of the clip can be determined on the Clip menu. 127 00:06:59,359 --> 00:07:03,526 A clip length of two to 60 seconds can be selected. 128 00:07:07,013 --> 00:07:09,794 The clip may be reviewed by selecting List 129 00:07:09,794 --> 00:07:13,877 in the patient exam list, and then pressing Play. 130 00:07:16,553 --> 00:07:20,004 When you have acquired all images and clips for the study, 131 00:07:20,004 --> 00:07:23,451 press the Patient key and choose End Exam 132 00:07:23,451 --> 00:07:26,303 from the onscreen menu to finalize the exam 133 00:07:26,303 --> 00:07:27,803 and end the study. 134 00:07:28,998 --> 00:07:32,068 This concludes this brief review of imaging modes 135 00:07:32,068 --> 00:07:36,525 and system controls to optimize the ultrasound image. 136 00:07:36,525 --> 00:07:39,901 For an extensive review of system features and functions, 137 00:07:39,901 --> 00:07:43,151 please refer to the system user guide.
