Essential Radiotherapy Techniques — Superficial and Orthovoltage What are superficial and orthovoltage treatments? Superficial SXT and Orthovoltage DXT radiotherapy utilise low energy ionizing radiation to treat cancer and other conditions that occur either on or close to the skin surface.
Quality Assurance information for Radiation Therapy Question 1. What is the energy range for superficial Crookes tube therapy machines? What machines had "hot cathode" tubes and generated medium energy ranges? Orthovoltage or deep therapy machines 3.
What is the energy range for orthovoltage machines? What are the five main components of a typical linear accelerator?
What are the 4 major components of the drive stand? Klystron or magnetron, waveguide, circulator, and water cooling system 6. What is a klystron? What is a magnetron? What is a waveguide? What are major components of the gantry?
What are the components of the treatment head? In a linear accelerator, what components helps create a uniform electron beam?
In a linear accelerator, microwave amplification occurs in the: On a conventional simulator what can be used to reduce unwanted scatter radiation? The conventional simulator design was meant to mimic what other piece of equipment? It was meant to simulate the mechanical, geometric, and optical conditions of a variety of treatment units Gantry, x-ray head and collimator, x-ray tube and generator, imaging device, and couch are all components of what simulator?
Conventional or fluoroscopic-based simulator On a conventional simulator, what defines the edge of the treatment field? Every image taken in conventional simulation should show evidence of what? A typical image intensifier contains what four major components?
A conventional simulator could potentially produce CT images. True if the machine has a CT mode. What are the two major methods of CT data acquisition?
In CT simulation, what does aperture size refer to? The diameter of the hole into which the patient is positioned Each small square on a CT image is called what? Window selection determines what in CT simulation? It determines what anatomy will be seen.
What are the two window selections that can be made? What does window level represent? It represents the center of the window width A pixel is a two-dimensional representation of what? On a conventional simulator, localizing lasers and ODI checks should be performed when and within what tolerance?for superficial x-ray therapy An integral part of the process is a powerful networkable verification & recording system for treatment planning and fully paperless documentation.
With the easy-to-use 3D ceiling mount available in the treatment rooms, a variety of settings are possible. The treatment options are diverse, including plastic surgical excision, Moh’s microsurgery, electrocautery, topical 5-fluorouracil and imiquimod, photodynamic therapy and superficial radiotherapy.
Advances in surgical techniques have meant that the population of patients treated with radiotherapy has changed. energies available to a radiotherapy program. Low-energy X ray beams have application in the treatment of skin lesions and shallow tumors.
The quality assurance . Ongoing Evaluation with a Strong Emphasis on Quality Assurance, Patient Quality of Life and Survivorship; Essential Radiotherapy Techniques – Superficial and Orthovoltage What are superficial and orthovoltage treatments?
Superficial (SXT) and Orthovoltage (DXT) radiotherapy utilise low energy ionizing radiation to treat cancer and other. What is Quality Assurance in radiology?
Quality Assurance (QA) is a plan of action to ensure that a diagnostic x-ray facility will produce consistent, high-quality images with a minimum of exposure to patients and personnel. Evaluation of depth dose characteristics of superficial X-rays machine using different kVp and applicators diameter M.
