This video is one of around 310 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and 1980s, thus constituting a contemporary medical-historical archive of great interest. The lectures mostly take place in a small and intimate studio setting and are often face-to-face. The lecturers use a wide variety of resources to illustrate their points, including film clips, slides, graphs, animated diagrams, charts and tables as well as 3-dimensional models and display boards with movable pieces. Some of the lecturers are telegenic while some are clearly less comfortable about being recorded; all are experts in their field and show great enthusiasm to share both the latest research and the historical context of their specialist areas.

Segment 1 Intertitle: Professor Boag. Xeroradiography. Boag shows a film radiograph and a xeroradiograph of a fibroadenoma. We see a diagram illustrating the process of xeroradiography. A short film is shown which shows the xeroradiographic screening of a femal patient's breasts. Film clip ends. Time start: 00:00:00:00 Time end: 00:05:02:00 Length: 00:05:02:00

Segment 2 Boag shows diagrams of the pattern of residual charge on a xeroradiograph. He compares a mamogram on a film and one on a xeroradiograph. He shows a venogram of a leg and a carotid angiogram taken by a xeroradiograph. Time start: 00:05:02:00 Time end: 00:10:15:00 Length: 00:05:13:00

Segment 3 Intertitle: Dr Colin Jones. Thermography. Jones introduces the subject of thermography. A short film is shown in which a female patient has her breast scanned. End of film clip. He shows a diagnostic thermogram and an infrared photograph of breasts. Time start: 00:10:15:00 Time end: 00:15:52:13 Length: 00:05:37:13

Segment 4 Jones shows a thermogram of a tumerous breast, then an infrared photograph of the same breast. He compares thermograms of normal breasts with those of breasts with tumours. Time start: 00:15:52:13 Time end: 00:21:57:14 Length: 00:06:05:01

Segment 5 Intertitle: Dr Kenneth Taylor. Ultrasound. Taylor describes how ultrasounds work. A short film is shown in which Taylor demonstrates a liver ultrasound. End of film clip. Time start: 00:21:57:14 Time end: 00:27:04:18 Length: 00:05:07:04

Segment 6 Taylor shows a series of chest x-rays and ultrasonograms. He then shows ultrasound scans of a gallbladder in a patient with obstructive jaundice and an ultrasound scan of a patient with gallstones. Time start: 00:27:04:18 Time end: 00:31:53:00 Length: 00:04:48:07

Segment 7 Taylor shows ultrasound scans of the bronchus of a patient with oat cell carcinoma. Further ultrasound scans are shown including one of the abdomen of a child with hepatoblastoma. Time start: 00:31:53:00 Time end: 00:36:12:00 Length: 00:04:19:00

Segment 8 Intertitle: New Radioisotopic Methods. Presented by Dr VR McReady. McReady shows radioisotopic scans and describes how the process works, particularly in differentiating different types of tumour. Time start: 00:36:12:00 Time end: 00:42:44:00 Length: 00:06:32:00
