June 2018, Birmingham and OSL welcomed ProSoma users who gathered over an evening buffet followed by a packed day of presentations and demos, discussing what the future will bring and how state-of-the art clinical practices are being implemented across the UK. A wide mix of topics from users and developers were discussed including:

First up was a demonstration of the new ProSoma Core module which can be added to ProSoma vsim to bring fast and accurate Monte Carlo dose and MU calc for simple palliative and static conformal techniques all within a single session on ProSoma adding just a minute or two to the simulation process. Also shown was how it can be used to perform a second check on all complex plans such as IMRT, VMAT, stereotactic plans.

Susan Barley from OSL demonstrated the power of scripting in ProSoma to speed and simplify workflows.

Jim Daniels, Head of Physics from Middlesbrough covered the commissioning of ProSoma Core and how it will be instrumental in modernising their clinical workflows and speeding up unplanned, palliative planning by the fast addition of a dose and MU calc in one vsim session, and how soon they will be rolling out the secondary plan and MU check for more complex techniques such as VMAT.

Amy Shaw, Advanced Practitioner in Lung and Upper GI from Southampton, described how ProSoma’s 4D CT functionality is used in the clinical workflow for 4D CT fusion 4D rapid contouring for treating lung SABR , are-planning of lung cases, and future 4DCT for Upper GI. Amy also made suggestions for future functionality, which was taken on board by the development team.

Nicola Young, Lead Clinical Scientist from Newcastle, detailed a new clinical pathway that has been developed using SPECT/CT and planning CT for the better targeting and treatment of Neuroblastoma. Nicola discussed the technical issues of using SPECT/CT and the practical solutions that had been developed in NCCC, and that this was the first time that SPECT/CT had been successfully utilised for RT planning, and stated that ProSoma was the only system in the centre’s arsenal of software systems, that could be used for fusion and contouring for these cases.

Stephen Hedley, Clinical Scientist from Newcastle, eloquently described their collaborative project on the principles and practicalities of using MR only planning for a range of anatomical sites and treatments. Whilst still work in progress, Stephen described how the gradual introduction of MR treatment machines could lead to the dose calculation from synthetic CT generated from MR image data, thereby potentially eliminating the need for planning and verification CTs.

Rob Chaldecott, Lead Physicist from the Genesis Southampton, brought his experience of how ProSoma is in extensive clinical use across many of the Genesis private centres by virtue of its remote networking capabilities. Using virtual machines and Citrix, Rob described the commissioning and implementation of the system. With just five ProSoma licenses, the Genesis group has enabled 65 doctors plus other employees, to log in remotely and use the full suite of clinical tools from beam placement, to contouring, fusion, 4D CT etc with the remote access system, that also allows OSL engineers to log in remotely and out of hours if needed, for routine maintenance and troubleshooting, without interrupting the clinical service delivery.
