catalyst radiotherapy

While Catalyst was not developed for the purpose of treating dogs the team at Lund University has demonstrated that Catalyst meets the requirements to monitor a dog’s position prior to starting the delivery of a dose of treatment The institution’s research not only demonstrates that the Catalyst system is effective for use in delivering FLASH-RT but that the system is flexible enough to consider a dog’s body …

 · Previously to the Catalyst™ C-RAD AB introduced the Sentinel™ system which has been evaluated in several studies While the Catalyst™ uses optical light to image the entire surface of its target the Sentinel™ uses a laser scanner to sample the surface line-by-line By observing the whole surface via one camera the Catalyst™ is able to calculate the surface in real time whereas the Sentinel™ reconstructs the …

Catalyst: amélioration du positionnement en radiothérapie, Un des problèmes majeurs de la radiothérapie est la fiabilité et la répétitivité du positionnement exact du patient au cours des 20 à 30 séances de radiothérapie avec une précision millimétrique, Les équipes du Centre améliorent la prise en charge des patientes en

How does C-RAD Catalyst HD enable research into FLASH

With both AlignRT® and Catalyst™ the position of the patient was monitored with three cameras The optical system compared the actual patient surface with the reference surface from the planning CT or from a reference surface acquired optically in the treatment room Initial positioning was aligned with tattoos and thereafter fine‐ tuned with SGRT, DIBH guidance was performed with SGRT,

Evaluation of daily patient positioning for radiotherapy

 · Given that the outcome of clinical radiotherapy RT is closely related to the radiolysis products from the interactions between the radiation and intracellular water an appropriate catalyst to promote radiolysis may improve the therapeutic efficacy However catalysis-based radiosensitization strategy remains under investigated, Herein, we propose a catalytic RT concept and synthesize Janus-like Au-Fe

Catalyst HD optical surface scanning and re-projection

Catalyst HD offers a complete Surface Image Guided Radiation Therapy SIGRT solution on SRT for online patient tracking before and during treatment delivery thus ensuring the best possible treatment outcome without non-prescribed doses The Catalyst HD can also be used for VMAT IMRT and 3D CRT delivery,

 · The DIBH technique was used for all left-sided breast patients with age <70 yr or otherwise healthy <75 yr Group A or age ≤80 yr Group C 25 of the patients were positioned with AlignRT ® Group A = Align and 25 patients were positioned with Catalyst™ Group C = Catalyst The mean patient ages were 57 yr range 44–76; Group A and 60 yr range 40–80; Group C, Candor's ConBine fixation device Candor, …

GETTING STARTED WITH SURFACE IMAGING

 · Fichier PDF

When a patient receives radiotherapy, linear accelerators linacs – Image 1 are used to deliver high energy x-ray photons to a targeted area of the body, These photons are absorbed by both cancerous cells and healthy tissue in the body, so it is important that radiotherapy can be given to maximise tumour kill whilst minimising normal tissue damage, this is known as the therapeutic ratio, Once the cancer cells have been targeted …

Structure-oriented catalytic radiosensitization for cancer

Purpose: Surface guided radiotherapy SGRT is reported as a feasible setup technique for whole-breast radiotherapy in deep inspiration breath hold DIBH but position errors of bony structures related to deeper parts of the target are not fully known The aim of this study was to estimate patient setup accuracy and margins obtained with two different SGRT workflows with and without daily kV- and/or MV-based image guidance IGRT

Catalyst offers a complete solution on 3D CRT, IMRT for online patient tracking before and during treatment delivery, thus ensuring the best possible therapeutic and palliative treatment outcome without non-prescribed doses, c4D software is integrated with major radiation therapy equipment suppliers to streamline workflow, including beam and couch control,

Conclusion: Optical surface scanning using Catalyst™ seems potentially useful for daily positioning at least to complement usual imaging modalities in most patients with acceptable accuracy although a significant improvement compared to skin mark based positioning could not be derived from the evaluated data However this effect seemed to be rather caused by the unexpected high accuracy of skin mark based positioning than …
