Migration of implanted markers for image‐guided lung tumor stereotactic ablative radiotherapy
The purpose of this study was to quantify postimplantation migration of percutaneously implanted cylindrical gold seeds ("seeds") and platinum endovascular embolization coils ("coils") for tumor tracking in pulmonary stereotactic ablative radiotherapy (SABR). We retrospectively analyzed the migration of markers in 32 consecutive patients with computed tomography scans postimplantation and at si...
متن کاملStability of percutaneously implanted markers for lung stereotactic radiotherapy
The purpose of this study was to evaluate the stability of complex markers implanted into lung tumors throughout a course of stereotactic body radiotherapy (SBRT). Fifteen patients referred for lung SBRT were prospectively included. Radio-opaque markers were implanted percutaneously, guided by computed tomography (CT). Deep inspiration breath-hold CT scans (BHCT) were acquired at planning and o...
متن کاملStereotactic ablative body radiotherapy for lung cancer.
Lung stereotactic ablative radiotherapy (SABR) is a method of delivering high 'ablative' doses of radiotherapy to tumours in the lung. It was developed at the Karolinska Institute in the early 1990s using the methods established in cranial radiosurgery with multiple beams prescribed to an isodose and using a custom designed stereotactic body frame for immobilisation. Since then, aligned with th...
متن کاملStereotactic ablative radiotherapy for lung cancer
Stereotactic ablative radiotherapy (SABR), which is also referred to as stereotactic body radiotherapy (SBRT), is defined as “the precise irradiation of an image defined extra-cranial lesion associated with the use of high radiation dose in a small number of fractions”. SABR is a relatively recent advance in the treatment of small peripheral non-small cell lung tumours. The concept of SABR was ...
متن کاملA fast model for prediction of respiratory lung motion for image-guided radiotherapy: A feasibility study
Background: The aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one CT dataset. Materials and Methods: For each of six patients with different thorax sizes, two sets of CT images were obtained in single-breath-hold inhale and exhale stages in the supine position. The CT images were then ...
