Description: 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 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
