Aim: During minimal access surgery an assistant is controlling the laparoscope and surgeon should be free to manipulate instruments. Although the advantages of laparoscopic surgery are well documented, one disadvantage is that, for optimum performance, an experienced camera driver is required who can provide the necessary views for the operating surgeon. There are many drawbacks in human camera...

Evaluation of thyroid uptake, by administration of small activities of radioactive iodine (I or I), is a well-defined procedure. Nowadays, nuclear medicine departments are using scintillation cameras coupled to pinhole collimators to perform such studies. On the other hand, gamma probes, which are normally used in radioguided surgical procedures, can technically be used for measuring the thyroi...

A scintillation camera and computer assembly is described whereby clinical and research scintigraphic data can be processed by a computer through a videotape transfer system. This assembly can provide a full computer capability to hospital clinics which are not equipped with a computer but still require convenient and rapid data analysis. Tomographic and anatomical marker data can also be acces...

BACKGROUND Ameloblastoma is a locally aggressive odontogenic neoplasm. With local recurrence rates reaching 90%, only completeness of excision can facilitate cure. Surgical clearance has widely been based on pre-operative imaging to guide operative excision margins, however use of intra-operative specimen x-ray or frozen-section has been sought to improve clearance rates, and advanced imaging t...

For radio-guided surgery on tumors using F-18-FDG, detection of annihilation gamma photons emanating from other parts of the body produces background radiation counts and limits its use in clinical situations. To overcome this limitation, we have developed an intra-operative positron probe with background-rejection capability. The positron probe uses a phoswich detector composed of a plastic sc...

Abstract Aims Intra-operative bleeding is very rarely a complication of laparoscopic appendicectomy. Despite this, it often mandatory for any patient undergoing an emergency appendicectomy to have pre-operative ABO blood type sampling. This could be unnecessary expense and may lead patients being delayed theatre. The aim this study was see how many who underwent required transfusion intra-opera...

OBJECTIVE This study compared the 123I thyroid uptake measurements obtained from a gamma camera fitted with a low-energy all-purpose (LEAP) collimator to those obtained from a thyroid uptake probe and gamma camera fitted with a pinhole (PH) collimator. METHODS Thirty-one patients (27 female and 4 male patients) were studied for comparison between a probe and a gamma camera fitted with LEAP co...
