Gross Tumor Volume an overview

Gross Volume

Is typically defined as macroscopic disease seen on the planning CT scan, usually identified using lung windowing on planning CT. In patients with significant surrounding consolidation secondary to obstruction or lung collapse, a PET scan can help identify regions of gross disease. IV contrast is of particular importance when outlining gross nodal disease. Historically, comprehensive elective nodal coverage with 2-D techniques was used to cover all potentially draining nodal stations, producing large volumes with significant morbidity. Practice eventually transitioned to involved nodal coverage, which has been shown to decrease morbidity without increasing rates of nodal failure. In 2023, the projected of the gig economy is expected to reach 455.2 billion U.S. dollars. The gig economy is commonly defined as digital platforms that allow freelancers to connect with potential clients for short-term jobs, contracted work, or asset-sharing.

Replacing complicated formulas and imprecise approaches, DTN Temperature Correction Index gives users confidence in the temperature of the fuel they are buying or selling and import this data directly into their operational and tax audit software. The effect of temperature changes on your fuel doesn’t need to be an unavoidable cost of doing business. While some try to compensate for seasonal variations, it tends to offer only a rough improvement based on an estimate. This compensation is true with contract sales as well – do you use a single temperature correction factor or a monthly adjustment? If a customer were to purchase 1000 gallons of gas to fill their insulated tanks, the gas would start to contract as it cools down to a regulated temperature. Even though 1000 gallons would leave the rack, less than 1000 gallons would be in the tank because it would contract back to its regular volume. In this case, the purchaser would have ended up with fewer gallons of gas than purchased.

Gross Merchandise Value (GMV): Definition, Formula, Pros and Cons, and Example

The target, however, does not come within 3mm of the skin nor does it extend into the pectoralis major, let alone the pectoralis minor, ribs, or lung. Thus, the actual CTV for clinical treatment would be the CTV resulting from the expansion limited by these other structures.

  • Dealers are truly now “drinking through a fire hose” with electronic leads.
  • GMV includes any fees or other deductions which a seller might calculate separately.
  • It is calculated by taking the number of units sold and multiplying by the profit per unit.
  • And that’s a good thing; technology and data are helping businesses to operate more efficiently than ever before.

The layer thickness of CT in the dataset of our study is about 5 times the pixel spacing in x and y directions, which is 3 times of that of the study of Chen , so it is more suitable to use 2.5D architecture (See Fig.4). Figure6 shows the results of automatic segmentation of the GTV of radiotherapy for lung cancer patients using UNet2D, UNet2.5D, Unet3D, ResSEUnet3D, ResSEUnet2.5D, and TransResUnet2.5D networks, respectively. Compared to the other network models, the segmentation results presented in this study are closer to the manual outline results of the radiotherapists. It can also be seen from Fig.6 that the segmentation results of the remaining five automatic segmentation networks showed false-positive discrete regions and under-segmentation.


The opposite happens when they are warm, and they expand, taking up more space. Let’s take a closer look at the impact your gasoline temperatures have on your bottom Gross Volume line – and what you can do to mitigate that impact. There’s nearly no end to how optimization can streamline operations and bolster profits when running any business.

How do you find gross volume?

Calculating gross volume requires totaling all receipts and including all sales and business transactions. The price paid by the purchaser of a product is the gross volume figure. This includes cash and credit transactions, retail and wholesale sales and Internet sales.
